This manual documents Dvips, a program to translate a DVI file into PostScript. It corresponds to version 5.66a (February 1997) of the Dvipsk distribution, a slightly modified variant of the original Dvips program with path searching rules consistent with the Web2c TeX implementation, the GNU font utilities, Xdvik, and Dviljk.
The Dvips program has a number of features that set it apart from other PostScript drivers for TeX. This rather long section describes the advantages of using Dvips, and may be skipped if you are just interested in learning how to use the program. See Installation, for details of compilation and installation.
The Dvips driver generates excellent, standard PostScript, that can be included in other documents as figures or printed through a variety of spoolers. The generated PostScript requires very little printer memory, so very complex documents with a lot of fonts can easily be printed even on PostScript printers without much memory, such as the original Apple LaserWriter. The PostScript output is also compact, requiring less disk space to store and making it feasible as a transfer format.
Even those documents that are too complex to print in their entirety on a particular printer can be printed, since Dvips will automatically split such documents into pieces, reclaiming the printer memory between each piece.
The Dvips program supports graphics in a natural way, allowing PostScript graphics to be included and automatically scaled and positioned in a variety of ways.
Printers with any resolution are supported, even if they have different resolutions in the horizontal and vertical directions. High resolution output is supported for typesetters, including an option that compresses the bitmap fonts so that typesetter virtual memory is not exhausted. This option also significantly reduces the size of the PostScript file and decoding in the printer is very fast.
Missing fonts can be automatically generated if Metafont exists on the system, or fonts can be converted from GF to PK format on demand. If a font cannot be generated, a scaled version of the same font at a different size can be used instead, although Dvips will complain loudly about the poor aesthetics of the resulting output.
Users will appreciate features such as collated copies and support for
tpic
, psfig
, emtex
, and METAPOST
; system
administrators will love the support for multiple printers, each with
their own configuration file, and the ability to pipe the output
directly to a program such as lpr
. Support for MS-DOS, OS/2, and
VMS in addition to Unix is provided in the standard distribution, and
porting to other systems is easy.
One of the most important features is the support of virtual fonts, which add an entirely new level of flexibility to TeX. Virtual fonts are used to give Dvips its excellent PostScript font support, handling all the font remapping in a natural, portable, elegant, and extensible way. Dvips even comes with its own Afm2tfm program that creates the necessary virtual fonts and TeX font metric files automatically from the Adobe font metric files.
Source is provided and freely distributable, so adding a site-specific feature is possible. Adding such features is made easier by the highly modular structure of the program.
There is really no reason to use another driver, and the more people use Dvips, the less time will be spent fighting with PostScript and the more time will be available to create beautiful documents. So if you don't use Dvips on your system, get it today.
Tom Rokicki wrote and maintains the original Dvips program.
(A copy of this chapter is in the distribution file dvipsk/INSTALL
.)
Installing Dvips is mostly the same as installing any Kpathsea-using
program. Therefore, for the basic steps involved,
see Installation. (A copy is in the file
kpathsea/INSTALL
.)
For solutions to common installation problems and information on how to
report a bug, see the file kpathsea/BUGS
(see Bugs). For solutions to Dvips-specific problems,
see Debug options. Also see the Dvips home page at
<http://www.radicaleye.com/dvips
>.
Dvips does require some additional installation, detailed in the sections below. Also, to configure color devices, see Color device configuration.
config.ps
installationDvips has its own configuration files: a file config.ps
for
sitewide defaults, and a file config.printer
for each
printer (output device). Since these are site-specific, make
install
does not create them; you must create them yourself.
(These Dvips configuration files are independent of the Kpathsea
onfiguration file texmf.cnf
(see Config files).
Dvips configuration files contents and searching are described fully in
Config files. The simplest way to create a new configuration file
is to copy and modify the file dvipsk/contrib/config.proto
,
seasoning with options to your taste from Config files. Here is
config.proto
for your reading pleasure:
% Prototype Dvips configuration file. % How to print, maybe with lp instead lpr, etc. o |lpr % Default resolution of this device, in dots per inch. D 600 % Metafont mode. (This is completely different from the -M command-line % option, which controls whether MakeTeXPK is invoked.) Get % <ftp://ftp.tug.org/tex/modes.mf
> for a list of mode names. This mode % and the D number above must agree, or MakeTeXPK will get confused. M ljfour % Memory available. Download the three-line PostScript file: % %!

Examples incontrib/papersize.level2
and %contrib/papersize.simple
.
To use PostScript fonts with TeX and Dvips, you need both metric
files (.tfm
and .vf
) and the outlines (.pfa
or
.pfb
). See Font concepts.
To support the basic PostScript font set, the recommended (and simplest)
approach is to retrieve <ftp://ftp.tug.org/tex/psfonts.tar.gz
> and
unpack it in your $(fontdir)
directory
(/usr/local/share/texmf/fonts
by default). This archive contains
metrics, outlines, and bitmaps (for previewing) for the 35 de facto
standard fonts donated by URW and the additional high-quality freely
available PostScript fonts donated by Adobe, Bitstream, and URW,
including geometrically-created variants such as oblique and small caps.
CTAN:/fonts/psfonts
contains support for many additional
fonts for which you must buy outlines (Adobe, Bigelow & Holmes,
Monotype, Softkey, Y&Y). psfonts.tar.gz
is a small extract from
this directory. (For CTAN info, see unixtex.ftp; a copy is in the top-level file INSTALL
.)
If you have additional PostScript fonts, you can make them available to
Dvips by (1) giving them with appropriate filenames; and (2) running
Afm2tfm (see Making a font available) to make TFM and VF metrics for
TeX and Dvips to use. Also add them to psfonts.map
if
necessary (see psfonts.map); it contains everything contained in
psfonts.tar.gz
and most fonts that come with Unix systems.
Following are locations for vendor-supplied fonts. Please mail tex-k@mail.tug.org if you find fonts elsewhere on your system.
The NeXT system supplies more fonts than any others, but there's a lot of overlap.
Finally, if you have an Hewlett-Packard printer, you should be able to
get Type 1 font files for the standard 35 fonts from HP, if the freely
available URW Type 1's do not satisfy for whatever reason. The phone
number for HP Printer Drivers is (in the United States) 303-339-7009.
The driver set to ask for is Adobe Type Manager 2.51, and the disk set
number is MP210en3
. Mentioning anything other than Microsoft
Windows when you ask for the driver set will likely lead to great
confusion on the other end.
Ghostscript is a PostScript interpreter freely available to end-users,
written by Peter Deutsch. It can read the PostScript produced by Dvips
and render it on your monitor, or for another device (e.g., an Epson
printer) that does not support PostScript, or in PDF format. The latest
version is available via <http://www.cs.wisc.edu/~ghost/index.html
>
and <ftp://ftp.cs.wisc.edu/pub/ghost/aladdin/
>.
A somewhat older version of Ghostscript is available under the GNU
General Public License, free to everyone. You can get that from
<ftp://prep.ai.mit.edu/pub/gnu/
>.
The program Ghostview, written by Tim Theisen, provides typical
previewing capabilities (next page/previous page, magnification, etc.).
It requires Ghostscript to run, and files in structured Postscript,
specifically with %%Page
comments (no N
in
config.ps
). You can get Ghostview from the same places as
Ghostscript.
You've gone through all the trouble of installing Dvips, carefully read all the instructions in this manual, and still can't get something to work. The following sections provide some helpful hints if you find yourself in such a situation.
For details on effective bug reporting, common installation problems,
and mktexpk
problems, see Bugs.
The -d
flag to Dvips helps in tracking down certain errors. The
parameter to this flag is an integer that tells what errors are
currently being tracked. To track a certain class of debug messages,
simply provide the appropriate number given below; if you wish to track
multiple classes, sum the numbers of the classes you wish to track. To
track all classes, you can use -1
. Another useful value is
3650
, which tracks everything having to do with file searching
and opening.
Some of these debugging options are actually provided by Kpathsea (see Debugging).
The classes are:
stat
calls
If you are not getting any output at all, even from the simplest
one-character file (for instance, \ \bye
), then something is very
wrong. Practically any file sent to a PostScript laser printer should
generate some output, at the very least a page detailing what error
occurred, if any. Talk to your system administrator about downloading a
PostScript error handler. (Adobe distributes a good one called
ehandler.ps
.)
It is possible, especially if you are using non-Adobe PostScript, that your PostScript interpreter is broken. Even then it should generate an error message. Dvips tries to work around as many bugs as possible in common non-Adobe PostScript interpreters, but doubtless it misses a few. PowerPage Revision 1, Interpreter Version 20001.001, on a Mitsubishi Shinko CHC-S446i color thermal dye sublimation printer is known to be unable to print with any but builtin fonts.
If Dvips gives any strange error messages, or compilation on your machine generated a lot of warnings, perhaps the Dvips program itself is broken. Try using the debug options to determine where the error occurred (see Debug options).
It is possible your spooler is broken and is misinterpreting the
structured comments. Try the -N
flag to turn off structured
comments and see what happens.
If some documents come out inverted or too small, probably your spooler
is not supplying an end of job indicator at the end of each file. (This
commonly happens on small machines that don't have spoolers.) You can
force Dvips to do this with the -F
flag (or F
config file
option), but this generates files with a terminating binary character
(control-D). You can also try using the -s
flag (or s
config file option) to enclose the entire job in a save/restore pair.
See Command-line options, and Config files.
If your printer returns error messages, the error message gives very
good information on what might be going wrong. One of the most common
error messages is bop undefined
. This is caused by old versions
of Transcript and other spoolers that do not properly parse the setup
section of the PostScript. To fix this, turn off structured comments
with the -N
option, but it'd be best to get your spooling
software updated.
Another error message is VM exhausted
. Some printers indicate
this error by locking up, others quietly reset. This is caused by Dvips
thinking that the printer has more memory than it actually does, and
then printing a complicated document. To fix this, try lowering the
m
parameter in the configuration file; use the debug option to
make sure you adjust the correct file.
Other errors may indicate you are trying to include graphics that don't nest properly in other PostScript documents, among other things. Try the PostScript file on a QMS PS-810 or other Adobe PostScript printer if you have one, or Ghostscript (see Ghostscript installation); it might be a problem with the printer itself.
This is usually caused by incorrectly specifying the amount of memory the printer has in the configuration file; see the previous section.
The most common problem with including graphics is an incorrect bounding box (see Bounding box). Complain to whoever wrote the software that generated the file if the bounding box is indeed incorrect.
Another possible problem is that the figure you are trying to include does not nest properly; there are certain rules PostScript applications must follow when generating files to be included. The Dvips program includes work-arounds for such errors in Adobe Illustrator and other programs, but there are certainly applications that haven't been tested.
One possible thing to try is the -K
flag which strips the comments
from an included figure. This might be necessary if the PostScript
spooling software does not read the structured comments correctly. Use
of this flag will break graphics from some applications, though, since
some applications read the PostScript file from the input stream,
looking for a particular comment.
Any application which generates graphics output containing raw binary (not ASCII hex) will probably fail with Dvips.
Dvips reads a DVI file as output by (for example) TeX, and converts it to PostScript, taking care of builtin or downloaded PostScript fonts, font reencoding, color, etc. These features are described in other chapters in this document.
There many ways to control Dvips' behavior: configuration files, environment variables, and command-line options.
To use Dvips at its simplest, simply type
dvips foo
where foo.dvi
is the output of TeX that you want to print. If
Dvips has been installed correctly, the document will probably roll out
of your default printer.
If you use fonts that have not been used on your system before, they may be automatically generated; this process can take a few minutes, so progress reports appear by default. The next time that document is printed, these fonts will have been saved in the proper directories, so printing will go much faster. (If Dvips tries to endlessly generate the same fonts over and over again, it hasn't been installed properly. See Unable to generate fonts.)
Many options are available (see the next section). For a brief summary of available options, just type
dvips --help
Dvips has a plethora of command line options. Reading through this section will give a good idea of the capabilities of the driver.
Here is a handy summary of the options; it is printed out when you run
Dvips with no arguments or with the standard --help
option.

page reversal, use -r0

usual. (The MS-DOS version will print to the local printer device
PRN
when name is |lpr

printer-specific configuration file.
This is useful for a printer that consistently offsets output pages by a
certain amount. You can use the file testpage.tex
to determine
the correct value for your printer. Be sure to do several runs with the

Dvips looks for many environment variables, to define search paths and
other things. The path variables are read as needed, after all
configuration files are read, so they override values in the
configuration files. (Except for TEXCONFIG
, which defines where
the configuration files themselves are found.)
See Path specifications, for details of interpretation of path and other environment variables common to all Kpathsea-using programs. Only the environment variables specific to Dvips are mentioned here.

This section describes in detail the Dvips-specific config.*
device configuration files (called *.cfg
on MS-DOS), which
override the texmf.cnf
configuration files generic to Kpathsea which Dvips also reads
(see Config files).
For information about installing these files, including a prototype file you can copy, see config.ps installation.
The Dvips program loads many different configuration files, so that parameters can be set globally across the system, on a per-device basis, or individually by each user.
config.ps
; it is searched for
along the path for Dvips configuration files, as described in
Supported file formats.
DVIPSRC
, if defined, is used as the specification of the startup
file. If this variable is undefined, Dvips uses a platform-specific
default name. On Unix Dvips looks for the default startup file under
the name $HOME/.dvipsrc
, which is in the user's home directory.
On MS-DOS and MS-Windows, where users generally don't have their private
directories, the startup file is called dvips.ini
and it is
searched for along the path for Dvips configuration files (as described
in Supported file formats.); users are
expected to set this path as they see fit for their taste.
-Pdevice
option
is encountered, at that point config.device
is loaded.
Thus, the printer configuration file can override anything in the
site-wide or user configuration file, and it can also override options
in the command line up to the point that the -P
option was
encountered. (On MS-DOS, the printer configuration files are called
device.cfg
, since DOS doesn't allow more than 3 characters
after the dot in filenames.)
-P
option was specified, and also the -o
and
-f
command line options were not used, Dvips checks the
environment variable PRINTER
. If it exists, then
config.$PRINTER
($PRINTER.cfg
on MS-DOS) is
loaded (if it exists).
Because the .dvipsrc
file is read before the printer-specific
configuration files, individual users cannot override settings in the
latter. On the other hand, the TEXCONFIG
path usually includes
the current directory, and can in any case be set to anything, so the
users can always define their own printer-specific configuration files
to be found before the system's.
A few command-line options are treated specially, in that they are not overridden by configuration files:
-D
config.$PRINTER
is
read, however, any D
or M
lines from there will take
effect.
-mode
M
line) in configuration files.
-mode
does not affect the resolution.
-o
o
line) in configuration files.
The purpose of these special cases is to (1) minimize the chance of
having a mismatched mode and resolution (which mktexpk
cannot
resolve), and (2) let command-line options override config files where
possible.
Most of the configuration file commands are similar to corresponding command line options, but there are a few exceptions. When they are the same, we omit the description here.
As with command line options, many may be turned off by suffixing the
letter with a zero (0
).
Within a configuration file, empty lines, and lines starting with a space, asterisk, equal sign, percent sign, or pound sign are ignored. There is no provision for continuation lines.

The number printed by this file is the total memory free; it is usually
best to tell Dvips that the printer has slightly less memory, because
many programs download permanent macros that can reduce the memory in
the printer. Some systems or printers can dynamically increase the
memory available to a PostScript interpreter, in which case this file
might return a ridiculously low number; for example, the NeXT computer
and Ghostscript. In these cases, a value of one million works fine.

map files pointed to by local configuration files that append to the
global map file. This can be used for font families.

Most TeX documents at a particular site are designed to use the standard paper size (letter size in the United States, A4 in Europe). The Dvips program can be customized either sitewide or for a particular printer.
But many documents are designed for other paper sizes. For instance, you may want to design a document that has the long edge of the paper horizontal. This can be useful when typesetting booklets, brochures, complex tables, or many other documents. This type of paper orientation is called landscape orientation (the default orientation is portrait). Alternatively, a document might be designed for ledger or A3 paper.
Since the intended paper size is a document design decision, not a
printing decision, such information should be given in the TeX file
and not on the Dvips command line. For this reason, Dvips supports a
papersize
special. It is hoped that this special will become
standard over time for TeX previewers and other printer drivers.
papersize
specialThe format of the papersize
special is
\special{papersize=width,height}
width is the horizontal size of the page, and height is the vertical size. The dimensions supported are the same as for TeX; namely, in (inches), cm (centimeters), mm (millimeters), pt (points), sp (scaled points), bp (big points, the same as the default PostScript unit), pc (picas), dd (didot points), and cc (ciceros).
For a US letter size landscape document, the papersize
would be:
\special{papersize=11in,8.5in}
An alternate specification of landscape
:
\special{landscape}
This is supported for backward compatibility, but it is hoped that
reventually the papersize
comment will dominate.
Of course, such a \special
only informs Dvips of the desired
paper size; you must also adjust \hsize
and \vsize
in your
TeX document typeset to those dimensions.
The papersize
special must occur somewhere on the first page of
the document.
The @
command in a configuration file sets the paper size
defaults and options. The first @
command defines the default
paper size. It has three possible parameters:
@ [name [hsize vsize]]
If @
is specified on a line by itself, with no parameters, it
instructs Dvips to discard all previous paper size information (possibly
from another configuration file).
If three parameters are given, with the first parameter being a name and
the second and third being a dimension (as in 8.5in
or
3.2cc
, just like in the papersize
special), then the
option is interpreted as starting a new paper size description, where
name is the name and hsize and vsize define the
horizontal and vertical size of the sheet of paper, respectively. For
example:
@ letterSize 8.5in 11in
If both hsize and vsize are zero (you must still specify
units!) then any page size will match. If the @
character is
immediately followed by a +
sign, then the remainder of the line
(after skipping any leading blanks) is treated as PostScript code to
send to the printer, presumably to select that particular paper size:
@ letter 8.5in 11in @+ %%BeginPaperSize: Letter @+ letter @+ %%EndPaperSize
After all that, if the first character of the line is an exclamation point, then the line is put in the initial comments section of the final output file; else, it is put in the setup section of the output file. For example:
@ legal 8.5in 14in @+ ! %%DocumentPaperSizes: Legal @+ %%BeginPaperSize: Legal @+ legal @+ %%EndPaperSize
When Dvips has a paper format name given on the command line, it looks
for a match by the name; when it has a papersize
special,
it looks for a match by dimensions. The first match found (in the order
the paper size information is found in the configuration file) is used.
If nothing matches, a warning is printed and the first paper size is
used. The dimensions must match within a quarter of an inch. Landscape
mode for all paper sizes is automatically supported.
If your printer has a command to set a special paper size, then give
dimensions of 0in 0in
; the PostScript code that sets the paper
size can refer to the dimensions the user requested as hsize
and
vsize
; these will be macros defined in the PostScript that return
the requested size in default PostScript units. Virtually all of the
PostScript commands you use here are device-dependent and degrade the
portability of the file; that is why the default first paper size entry
should not send any PostScript commands down (although a structured
comment or two would be okay). Also, some printers want
BeginPaperSize
comments and paper size setting commands; others
(such as the NeXT) want PaperSize
comments and they will handle
setting the paper size. There is no solution I could find that works
for both (except maybe specifying both).
The Perl 5 script contrib/mkdvipspapers
in the distribution
directory may help in determining appropriate paper size definitions.
If your printers are configured to use A4 paper by default, the
configuration file (probably the global config.ps
in this case)
should include this as the first @
command:
@ A4size 210mm 297mm @+ %%PaperSize: A4
so that A4size
is used as the default, and not A4
itself;
thus, no PostScript a4
command is added to the output file,
unless the user explicitly says to use paper size a4
. That is,
by default, no paper size PostScript command should be put in the
output, but Dvips will still know that the paper size is A4 because
A4size
is the first (and therefore default) size in the
configuration file.
Executing the letter
or a4
or other PostScript operators
cause the document to be nonconforming and can cause it not to print on
certain printers, so the default paper size should not execute such an
operator if at all possible.
Some printers, such as the Hewlett-Packard HP4si, have multiple paper
trays. You can set up Dvips to take advantage of this using the
bop-hook
PostScript variable (see PostScript hooks).
For example, suppose you have an alternate tray stocked with letterhead
paper; the usual tray has the usual paper. You have a document where
you want the first page printed on letterhead, and the remaining pages
on the usual paper. You can create a header file, say
firstletterhead.PS
, with the following (PostScript) code
(bop-hook
is passed the current physical page number, which
starts at zero):
/bop-hook { dup 0 eq { alternatetray } { normaltray } ifelse } def
where alternatetray and normaltray are the appropriate
commands to select the paper trays. On the 4SI, alternatetray is
statusdict begin 1 setpapertray end
and normaltray is
statusdict begin 0 setpapertray end
.
Then, include the file with either
-h
command-line option (see Option details); or
h
config file option (see Configuration file commands); or
\special{header=file}
in your TeX document
(see Including headers from TeX).
Dvips supports inclusion of PostScript figure files (e.g., Encapsulated PostScript), downloading other header files (e.g., fonts), including literal PostScript code, and hypertext.
Scaling and including PostScript graphics is a breeze--if the PostScript file is correctly formed. Even if it is not, however, the file can usually be accommodated with just a little more work.
The most important feature of a good PostScript file from the standpoint of including it in another document is an accurate bounding box comment. Every well-formed PostScript file has a comment describing where on the page the graphic is located, and how big that graphic is.
This information is given as the lower left and upper right corners of the box just enclosing the graphic, and is thus referred to as the bounding box. These coordinates are given in the default PostScript units (there are precisely 72 PostScript units to the inch, like TeX big points) with respect to the lower left corner of the sheet of paper.
To see if a PostScript file has a bounding box comment, just look at the first few lines of the file. PostScript files are standard ASCII, so you can use any text editor to do this. If within the first few dozen lines there is a line like
%%BoundingBox: 25 50 400 300
(with any reasonable numbers), chances are very good that the file is Encapsulated PostScript and will work easily with Dvips. If the file contains instead a line like
%%BoundingBox: (atend)
the file is still probably Encapsulated PostScript, but the bounding box is given at the end of the file. Dvips needs it at the beginning. You can move it with that same text editor, or a simple script. (The bounding box is given in this way when the program that generated the PostScript couldn't know the size in advance, or was too lazy to compute it.)
If the document lacks a %%BoundingBox:
altogether, you can
determine one in a couple of ways. One is to use the bbfig
program distributed with Dvips in the contrib
directory. This can
usually find the correct bounding box automatically; it works best with
Ghostscript.
If the comment looks like this:
%%BoundingBox: 0 0 612 792
the graphic claims to take up an entire sheet of paper. This is usually a symptom of a bug in the program that generated it.
The other is to do it yourself: print the file. Now, take a ruler, and make the following measurements (in PostScript units, so measure in inches and multiply by 72): From the left edge of the paper to the leftmost mark on the paper is llx, the first number. From the bottom edge of the paper to the bottommost mark on the paper is lly, the second number. From the left edge of the paper to the rightmost mark on the paper is urx, the third number. The fourth and final number, ury, is the distance from the bottom of the page to the uppermost mark on the paper.
Once you have the numbers, add a comment of the following form as the
second line of the document. (The first line should already be a line
starting with the two characters %!
; if it is not, the file
probably isn't PostScript.)
%%BoundingBox: llx lly urx ury
Or, if you don't want to modify the file, you can simply write these numbers down in a convenient place and give them in your TeX document when you import the graphic, as described in the next section.
If the document does not have such a bounding box, or if the bounding box is given at the end of the document, or the bounding box is wrong, please complain to the authors of the software package that generated the file.
Once the figure file has a bounding box comment (see the previous
section,) you are ready it the graphic into a TeX document. Many
packages for using EPS files exist. One distributed with Dvips is the
files epsf.tex
(for plain TeX) and epsf.sty
(for
LaTeX). For plain TeX, add a line like this near the top of your
input file:
\input epsf
If you are using LaTeX 2e, use the graphics
or graphicx
package.
If you are using LaTeX 2.09, add the epsf
style option, as in:
\documentstyle[12pt,epsf]{article}
In any case, the above only needs to be done once, no matter how many figures you plan to include.
Now, at the point you want to include a file, enter a line such as:
\epsffile{foo.eps}
If you are using LaTeX, you may need to add \leavevmode
immediately before the \epsffile
command to get certain
environments to work correctly. If your file does not have a bounding
box comment, you can supply the numbers as determined in the previous
section, in the same order they would have been in a normal bounding box
comment:
\epsffile[100 100 500 500]{foo.ps}
Now, save your changes and run TeX and Dvips; the output should have your graphic positioned at precisely the point you indicated, occupying the proper amount of space.
The \epsffile
macro typesets the figure as a TeX \vbox
at the point of the page that the command is executed. By default, the
graphic will have its `natural' width (namely, the width of its bounding
box). The TeX box will have depth zero and its natural height. By
default, the graphic will be scaled by any DVI magnification in effect,
just as is everything else in your document. See the next section for
more information on scaling.
If you want TeX to report the size of the figure as a message on your terminal when it processes each figure, give the command:
\epsfverbosetrue
Usually, you will want to scale an EPSF figure to some size appropriate for your document, since its natural size is determined by the creator of the EPS file.
The best way to do this is to assign the desired size to the TeX
\epsfxsize
or \epsfysize
variables, whichever is more
convenient for you. That is, put
\epsfxsize=dimen
right before the call to \epsffile
. Then the width of the TeX
box will be dimen and its height will be scaled proportionately.
Similarly, you can set the vertical size with
\epsfysize=dimen
in which case the height will be set and the width scaled proportionally.
If you set both, both will be honored, but the aspect ratio of the included graphic may necessarily be distorted, i.e., its contents stretched in one direction or the other.
You can resize graphics in a more general way by redefining the
\epsfsize
macro. \epsffile
calls this with two
parameters: the natural horizontal and vertical sizes of the PostScript
graphic. \epsfsize
must expand to the desired horizontal size,
that is, the width of the \vbox
. Schematically:
\def\epsfsize#1#2{body}
Some useful definitions of body:
\epsfxsize
\epsfxsize
to the same value it had before the macro
was called.
#1
0pt
#1
.
0.5#1
\hsize
\hsize
. (In LaTeX, use \textwidth
instead of \hsize
.)
\ifnum#1>\hsize\hsize\else#1\fi
\hsize
, scale to
\hsize
, otherwise use the natural width.
For compatibility with other PostScript drivers, it is possible to turn off the default scaling of included figures by the DVI magnification with the following TeX command:
\special{! /magscale false def}
Use of this command is not recommended because it will make the
\epsffile
graphics the "wrong" size if global magnification is
being used, and it will cause any PostScript graphics to appear
improperly scaled and out of position if a DVI to DVI program is used to
scale or otherwise modify the document.
DVI magnification is not applied to any output from code you write in
bop-hook
or its ilk (see PostScript hooks),
By default, clipping is disabled for included EPSF images. This is because clipping to the bounding box dimensions often cuts off a small portion of the figure, due to slightly inaccurate bounding box arguments. The problem might be subtle; lines around the boundary of the image might be half their intended width, or the tops or bottoms of some text annotations might be sliced off. If you want to turn clipping on, just use the command
\epsfclipon
and to turn clipping back off, use
\epsfclipoff
psfile
specialThe basic special for file inclusion is as follows:
\special{psfile=filename.ps [key=value] ... }
This downloads the PostScript file filename.ps
such that
the current point will be the origin of the PostScript coordinate
system. The optional key=value assignments allow you to
specify transformations on the PostScript.
The possible keys are:
hoffset
voffset
hsize
vsize
hscale
vscale
angle
clip
The dimension parameters are all given in PostScript units.
The hscale
and vscale
are given in non-dimensioned percentage
units, and the rotation value is specified in degrees.
Thus
\special{psfile=foo.ps hoffset=72 hscale=90 vscale=90}
will shift the graphics produced by file foo.ps
right by one inch
and will draw it at 0.9 times normal size. Offsets are given relative
to the point of the special command, and are unaffected by scaling or
rotation. Rotation is counterclockwise about the origin. The order of
operations is to rotate the figure, scale it, then offset it.
For compatibility with older PostScript drivers, it is possible to change
the units that hscale
and vscale
are given in. This can be
done by redefining @scaleunit
in SDict
by a TeX command such as
\special{! /@scaleunit 1 def}
The @scaleunit
variable, which is by default 100, is what
hscale
and vscale
are divided by to yield an absolute
scale factor.
PostScript is an excellent page description language--but it does tend
to be rather verbose. Compressing PostScript graphics files can reduce
them by factor of five or more. For this reason, if the name of an
included PostScript file ends with .Z
or .gz
, Dvips
automatically runs gzip -d
. For example:
\epsffile[72 72 540 720]{foo.ps.gz}
Since the results of such a command are not accessible to TeX, if you
use this facility with the epsf
macros, you need to supply the
bounding box parameter yourself, as shown.
More generally, if the filename parameter to one of the graphics
inclusion techniques starts with a left quote (`
), the parameter
is instead interpreted as a command to execute that will send the actual
file to standard output. For example:
\special{psfile="`gnuplot foo"}
to include the file foo
. Of course, the command to be executed
can be anything, including using a file conversion utility such as
tek2ps
or whatever is appropriate. This feature can be disabled
with the -R
command-line option or R
configuration option.
You can use any font available to TeX and Dvips within a graphics
file by putting a %*Font:
line in the leading commentary of the
file. Schematically, this looks like:
%*Font: tfmname scaledbp designbp hex-start:hex-bitstring
Here is the meaning of each of these elements:
cmr10
. You can give the same
tfmname on more than one %*Font
line; this is useful when
the number of characters from the font used needs a longer
hex-bitstring (see item below) than conveniently fits on one line.
cmr10
,
it should be 9.96265
.
4b
or 4B
for
K
.
K
, you would use 4b:8
for hex-start and
hex-bitstring. If it used KLMNP
, you would use
4b:f4
.
MetaPost's output figures contain lines like this for bitmap fonts used in a MetaPost label (see MetaPost).
Header files are bits of PostScript included in the output file; generally they provide support for special features, rather than producing any printed output themselves. You can explicitly request downloading header files if necessary for some figure, or to achieve some special effect.
Dvips includes some headers on its own initiative, to implement features
such as PostScript font reencoding, bitmap font downloading, handling of
\special
's, and so on. These standard headers are the
.pro
files (for "prologue") in the installation directory
$(psheaderdir)
; they are created from the .lpro
("long
prologue") files in the distribution by stripping
comments, squeezing blank lines, etc., for maximum efficiency. If you
want to peruse one of the standard header files, read the .lpro
version.
The PostScript dictionary stack will be at the userdict
level
when header files are included.
In order to get a particular graphic file to work, a certain font or
header file might need to be sent first. The Dvips program provides
support for this with the header
\special
. For instance,
to ensure that foo.ps
gets downloaded:
\special{header=foo.ps}
As another example, if you have some PostScript code that uses a PostScript font not built into your printer, you must download it to the printer. If the font isn't used elsewhere in the document, Dvips can't know you've used it, so you must include it in the same way, as in:
\special{header=putr.pfa}
to include the font definition file for Adobe Utopia Roman.
You can include headers when you run Dvips, as well as from your
document (see the previous section). To do this, run Dvips with the
option -P header
; this will read the file
config.header
, which in turn can specify a header file to
be downloaded with the h
option. See Configuration file commands. These files are called header.cfg
on MS-DOS.
You can arrange for the same file to serve as a -P
config file
and the downloadable header file, by starting the lines of PostScript
code with a space, leaving only the h
line and any comments
starting in the first column. As an example, see
contrib/volker/config.*
(contrib/volker/*.cfg
on MS-DOS).
(These files also perform useful functions: controlling duplex/simplex
mode on duplex printers, and setting various screen frequencies;
contrib/volker/README
explains further.)
Dvips tries to avoid overflowing the printer's memory by splitting the
output files into "sections" (see the -i
option in Option details). Therefore, for all header files, Dvips debits the printer VM
budget by some value. If the header file has, in its leading
commentary a line of the form
%%VMusage: min max
then max is used. If there is no %%VMusage
line, then
the size (in bytes) of the header file is used as an approximation.
Illustrations (figure files) are also checked for %%VMusage
line.
You can include literal PostScript code in your document in several ways.
"
special: Literal PostScriptFor simple graphics, or just for experimentation, literal PostScript
code can be included. Simply use a \special
beginning with a
double quote character "
; there is no matching closing "
.
For instance, the following (simple) graphic:
[ picture of a grey triangle ]
was created by typing:
\vbox to 100bp{\vss % a bp is the same as a PostScript unit \special{" newpath 0 0 moveto 100 100 lineto 394 0 lineto closepath gsave 0.8 setgray fill grestore stroke}}
You are responsible for leaving space for such literal graphics, as with
the \vbox
above.
ps
specialGenerally, Dvips encloses specials in a PostScript save/restore pair,
guaranteeing that the special will have no effect on the rest of the
document. The ps
special, however, allows you to insert literal
PostScript instructions without this protective shield; you should
understand what you're doing (and you shouldn't change the PostScript
graphics state unless you are willing to take the consequences). This
command can take many forms because it has had a torturous history; any
of the following will work:
\special{ps:text} \special{ps::text} \special{ps::[begin]text} \special{ps::[end]text}
(with longer forms taking precedence over shorter forms, when they are
present). ps::
and ps::[end]
do no positioning, so they
can be used to continue PostScript literals started with ps:
or
ps::[begin]
.
In addition, the variant
\special{ps: plotfile filename}
inserts the contents of filename verbatim into the output (except
for omitting lines that begin with %). An example of the proper use of
literal specials can be found in the file rotate.tex
, which makes
it easy to typeset text turned in multiples of 90 degrees.
!
\special
You can download literal PostScript header code in your TeX document,
for use with (for example) literal graphics code that you include later.
The text of a \special
beginning with an !
is copied into
the output file. A dictionary SDict
will be current when this
code is executed; Dvips arranges for SDict
to be first on the
dictionary stack when any PostScript graphic is included, whether
literally (the "
special) or through macros (e.g.,
epsf.tex
).
For example:
\special{! /reset { 0 0 moveto} def}
Besides including literal PostScript at a particular place in your document (as described in the previous section), you can also arrange to execute arbitrary PostScript code at particular times while the PostScript is printing.
If any of the PostScript names bop-hook
, eop-hook
,
start-hook
, or end-hook
are defined in userdict
,
they will be executed at the beginning of a page, end of a page, start
of the document, and end of a document, respectively.
When these macros are executed, the default PostScript coordinate system
and origin is in effect. Such macros can be defined in headers added by
the -h
option or the header=
special, and might be useful
for writing, for instance, `DRAFT' across the entire page, or, with the
aid of a shell script, dating the document. These macros are executed
outside of the save/restore context of the individual pages, so it is
possible for them to accumulate information, but if a document must be
divided into sections because of memory constraints, such added
information will be lost across section breaks.
The single argument to bop-hook
is the physical page number; the
first page gets zero, the second one, etc. bop-hook
must leave
this number on the stack. None of the other hooks are passed arguments.
As an example of what can be done, the following special will write a light grey `DRAFT' across each page in the document:
\special{!userdict begin /bop-hook{gsave 200 30 translate 65 rotate /Times-Roman findfont 216 scalefont setfont 0 0 moveto 0.7 setgray (DRAFT) show grestore}def end}
Using bop-hook
or eop-hook
to preserve information across
pages breaks compliance with the Adobe document structuring conventions,
so if you use any such tricks, you may also want to use the -N
option to turn off structured comments (such as %%Page
).
Otherwise, programs that read your file will assume its pages are
independent.
To finish off this section, the following examples of literal PostScript are presented without explanation:
\def\rotninety{\special{ps:currentpoint currentpoint translate 90 rotate neg exch neg exch translate}}\font\huge=cmbx10 at 14.4truept \setbox0=\hbox to0pt{\huge A\hss}\vskip16truept\centerline{\copy0 \special{ps:gsave}\rotninety\copy0\rotninety\copy0\rotninety \box0\special{ps:grestore}}\vskip16truept
[ There are 4 A
characters, each rotated 90 degrees about a
common center point ]
\vbox to 2truein{\special{ps:gsave 0.3 setgray}\hrule height 2in width\hsize\vskip-2in\special{ps:grestore}\font\big=cminch\big \vss\special{ps:gsave 1 setgray}\vbox to 0pt{\vskip2pt \line{\hss\hskip4pt NEAT\hss}\vss}\special{ps:0 setgray}% \hbox{\raise2pt\line{\hss NEAT\hss}\special{ps:grestore}}\vss}
[ There is a big gray box with the word NEAT
inside in big letters ]
Some caveats are in order, however. Make sure that each gsave
is
matched with a grestore
on the same page. Do not use save
and restore
; they can interact with the PostScript generated by
Dvips if care is not taken. Try to understand what the above macros are
doing before writing your own. The \rotninety
macro especially
has a useful trick that appears again and again.
Dvips has support for producing hypertext PostScript documents. If you
specify the -z
option, the html:
specials described below
will be converted into pdfmark
PostScript operators to specify
links. Without -z
, html:
specials are ignored.
The resulting PostScript can then be processed by a distiller program to make a PDF file. (It can still be handled by ordinary PostScript interpreters as well.) Various versions of both PC and Unix distillers are supported; Ghostscript includes limited distiller support (see Ghostscript installation).
Macros you can use in your TeX document to insert the specials in the
first place are available from CTAN:/support/hypertex
. For
CTAN info, see unixtex.ftp.
This hypertext support (and original form of the documentation) was
written by Mark Doyle and Tanmoy Bhattacharya as the dvihps
program. You can retrieve their software and additional documentation
via the CTAN reference above. You may also be interested in the Java
previewer IDVI, available at <http://www.win.tue.nl/~dickie/idvi

the process of making PDF files from TeX files in more detail.
Mail archives for the original project are at

If you intend to go all the way to PDF, you will probably want to use PostScript fonts exclusively, since the Adobe PDF readers are extremely slow when dealing with bitmap fonts. Commercial versions of the Computer Modern fonts are available from Blue Sky; public domain versions are available from CTAN sites (for CTAN info, see unixtex.ftp) in:
fonts/postscript/bakoma fonts/postscript/paradissaYou may need to modify these fonts; see <
http://xxx.lanl.gov/faq/bakoma.html
>.
Also, the Adobe distillers prior to 2.1 drop trailing space characters
(character code 32) from strings. Unfortunately, the PostScript fonts
use this character code for characters other than space (notably the
Greek letter psi in the Symbol
font), and so these characters are
dropped. This bug is fixed in version 2.1.
If you can't upgrade, One workaround is to change all the trailing
blanks in strings to a character code that isn't in the font. This works
because the default behavior is to substitute a blank for a missing
character, i.e., the distiller is fooled into substituting the right
character. For instance, with the Blue Sky fonts, you can globally
replace )
with \200)
(with sed
, for example) and
get the desired result. With the public domain fonts, you will probably
have to use a character code in the range 128 to 191 since these fonts
duplicate the first 32 characters starting at 192 to avoid MS-DOS
problems.
Current support for the World Wide Web in the TeX system does not involve modifying TeX itself. We need only define some specials; Arthur Smith (apsmith@aps.org), Tanmoy Bhattacharya, and Paul Ginsparg originally proposed and implemented the following:
html:<a href="xurl"> html:<a name="name"> html:</a> html:<img src="xurl"> html:<base href="xurl">
Like all TeX \special
's, these produce no visible output, and
are uninterpreted by TeX itself. They are instructions to DVI
processors only.
Here, xurl is a standard WWW uniform resource locator (URL),
possibly extended with a #type.string
construct,
where type is page
, section
, equation
,
reference
(for bibliographic references), figure
,
table
, etc. For example,
\special{html:<a href="http://www.maths.tcd.ie/~tim/ch1.dvi#equation.1.1">}is a link to equation (1.1) in an example document by Tim Murphy.
See <http://www.w3.org/hypertext/WWW/Addressing/Addressing.html
>
for a precise description of base URL's. (That itself is a URL, in case
you were wondering.)

Typically unnecessary, as the name of the DVI file being read is used by
default.
The img
and base

the NeXTSTEP DVI viewer.
Dvips supports the use of PostScript fonts in TeX documents. To use a PostScript font conveniently, you need to prepare a corresponding virtual font; the program Afm2tfm, supplied with Dvips, helps with that.
All the necessary support for the standard 35 PostScript fonts
(AvantGarde-Book
through ZapfDingbats
), plus other freely
or commonly available PostScript fonts is available along with Dvips.
To use these fonts, you need do nothing beyond what is mentioned in the
installation procedure (see Installation). This chapter is
therefore relevant only if you are installing new PostScript fonts not
supplied with Dvips. (Or if you're curious.)
The information needed to typeset using a particular font is contained in two files: a metric file that contains shape-independent information and a glyph file that contains the actual shapes of the font's characters. A virtual font is an optional additional file that can specify special ways to construct the characters. TeX itself (or LaTeX) look only at the metric file, but DVI drivers such as Dvips look at all three of these files.
An encoding file defines the correspondence between the code numbers of the characters in a font and their descriptive names. Two encoding files used together can describe a reencoding that rearranges, i.e., renumbers, the characters of a font.
A metric file describes properties of the font that are independent of what the characters actually look like. Aside from general information about the font itself, a metric file has two kinds of information: information about individual characters, organized by character code, and information about sequences of characters.
The per-character information specifies the width, height, depth, and italic correction of each character in the font. Any might be zero.
In addition to information on individual characters, the metric file
specifies kerning, i.e., adding or removing space between
particular character pairs. It further specifies ligature
information: when a sequence of input characters should be typeset as a
single (presumably different) "ligature" character. For example, it's
traditional for the input fi
to be typeset as `fi', not as
`fi' (with the dot of the `i' colliding with `f'). (In English,
the only common ligatures are fi, fl, ff, ffi, and ffl.)
Different typesetting systems use different metric file formats:
.afm
)
file. These files are plain text, so you can inspect them easily. You
can get AFM files for Adobe's fonts from
<ftp://ftp.adobe.com/pub/adobe/Fonts/AFMs
>.
.tfm
) files. When you say
\font = font
in your TeX document, TeX reads a file
named font.tfm
. (Well, except for the texfonts.map
feature; see Fontmap). TeX can then
calculate the space occupied by characters from the font when
typesetting. In addition, the DVI drivers you use to print or view the
DVI file produced by TeX may need to look at the TFM file.
TFM files are binary (and hence are typically much smaller than AFM
files). You can use the tftopl
program (see tftopl invocation) that comes with TeX to transform a TFM
file into a human-readable "property list" (.pl
) file. You can
also edit a PL file and transform it back to a TeX-readable TFM with
the companion program pltotf
(see pltotf invocation). Editing metrics by hand is not something you're likely to want
to do often, but the capability is there.
.pfm
) files. These are binary files. They are irrelevant in the
TeX world, and not freely available, so we will not discuss them
further.
The Afm2tfm program distributed with Dvips converts an AFM file to a TFM file and performs other useful transformations as well. See Invoking afm2tfm.
Although a metric file (see the previous section) contains information about the spatial and other properties of the character at position 75, say, it contains nothing about what the character at position 75 actually looks like. The glyphs--the actual shapes of the letterforms in a font--are defined by other files, which we call glyph files. TeX itself only reads the TFM file for a font; it does not need to know character shapes.
A glyph file is a file that defines the shapes of the characters in a font. The shapes can be defined either by outlines or by bitmaps.
PostScript fonts are defined as outline fonts: Each character in the font is defined by giving the mathematical curves (lines, arcs, and splines) that define its contours. Different sizes of a character are generated by linearly scaling a single shape. For example, a 10-point `A' is simply half the size of a 20-point `A'. Nowadays, outline fonts usually also contain hints--additional information to improve the appearance of the font at small sizes or low resolutions.
Although various kinds of PostScript outline fonts exist, by far the
most common, and the only one we will consider, is called Type 1.
The glyph files for Postscript Type 1 fonts typically have names ending
in .pfa
("printer font ASCII") or .pfb
("printer font
binary").
In contrast, glyph files for Computer Modern and the other standard
TeX fonts are bitmap fonts, generated from Metafont
(.mf
) descriptions. The Metafont program distributed with TeX
generates bitmaps from these descriptions.
The glyph files for TeX bitmap fonts are usually stored in
packed font (PK) files. The names of these files end in
.nnnpk
, where nnn is the resolution of the font in
dots per inch. For example, cmr10.600pk
contains the bitmaps for
the cmr10
font at a resolution of 600dpi. (On DOS
filesystems, it's more likely dpi600\cmr10.pk
.)
Metafont actually outputs generic font (GF) files, e.g.,
cmr10.600gf
, but the GF files are usually converted immediately
to PK format (using the gftopk
utility that comes with TeX)
since PK files are smaller and contain the same information. (The GF
format is a historical artifact.)
A virtual font is constructed by extracting characters from one or
more existing fonts and rearranging them, or synthesizing new characters
in various ways. The explanation in this manual is intended to suffice
for understanding enough about virtual fonts to use them with Dvips. It
isn't a reference manual on virtual fonts. For more information: The
primary document on virtual fonts is Donald E. Knuth, TUGboat
11(1), Apr. 1990, pp. 13-23, "Virtual Fonts: More Fun for Grand
Wizards" (CTAN:/info/virtual-fonts.knuth
; for CTAN info,
see unixtex.ftp). (Don't be intimidated by
the subtitle.)
A virtual font (.vf
) file specifies, for each character in the
virtual font, a recipe for typesetting that character. A VF file, like
a TFM file, is in a compressed binary format. The vftovp
and
vptovf
programs convert a VF file to a human-readable VPL
(virtual property list) format and back again. See vftovp invocation, and vptovf invocation.
In the case of a PostScript font f being used in a straightforward way, the recipe says: character i in the VF font is character j in font f. The font f is called a base font. For example, the VF file could remap the characters of the PostScript font to the positions where TeX expects to find them. See Encodings.
Since TeX reads only TFM files, not VF's, each VF must have a
corresponding TFM for use with TeX. This corresponding TFM is
created when you run vptovf
.
You can expand virtual fonts into their base fonts with DVIcopy (see dvicopy invocation). This is useful if you are using a DVI translator that doesn't understand vf's itself.
Every font, whatever its type, has an encoding, that specifies the correspondence between "logical" characters and character codes. For example, the ASCII encoding specifies that the character numbered 65 (decimal) is an uppercase `A'. The encoding does not specify what the character at that position looks like; there are lots of ways to draw an `A', and a glyph file (see Glyph files) tells how. Nor does it specify how much space that character occupies; that information is in a metric file (see Metric files).
TeX implicitly assumes a particular encoding for the fonts you use
with it. For example, the plain TeX macro \'
, which typesets
an acute accent over the following letter, assumes the acute accent is
at position 19 (decimal). This happens to be true of standard TeX
fonts such as Computer Modern, as you might expect, but it is not true
of normal PostScript fonts.
It's possible but painful to change all the macros that assume particular character positions. A better solution is to create a new font with the information for the acute accent at position 19, where TeX expects it to be. See Making a font available.
PostScript represents encodings as a sequence of 256 character names
called an encoding vector. An encoding file (.enc
)
gives such a vector, together with ligature and kerning information
(with which we are not concerned at the moment). These encoding files
are used by the Afm2tfm program. Encoding files are also downloaded to
the PostScript interpreter in your printer if you use one of them in
place of the default encoding vector for a particular PostScript font.
Examples of encodings: the dvips.enc
encoding file that comes
with Dvips in the reencode
directory is a good (but not perfect)
approximation to the TeX encoding for TeX's Computer Modern text
fonts. This is the encoding of the fonts that originated with Dvips,
such as ptmr.tfm
. The distribution includes many other encoding
files; for example, 8r.enc
, which is the base font for the
current PostScript font distribution, and three corresponding to the
TeX mathematics fonts: texmext.enc
for math extensions,
texmital.enc
for math italics, and texmsym.enc
for math
symbols.
The output of Dvips is a program in the PostScript language that instructs your (presumably PostScript-capable) printer how to typeset your document by transforming it into toner on paper. Your printer, in turn, contains a PostScript interpreter that carries out the instructions in this typesetting program.
The program must include the definition of any PostScript fonts that you
use in your document. Fonts built into your printer (probably the
standard 35: Times-Roman
, ZapfDingbats
, ...) are
defined within the interpreter itself. Other fonts must be downloaded
as pfa or pfb files (see Glyph files) from your host (the computer
on which you're running Dvips).
You may be wondering exactly how a PostScript interpreter figures out what character to typeset, with this mass of metrics, glyphs, encodings, and other information. (If you're not wondering, skip this section ...)
The basic PostScript operator for imaging characters is
show
. Suppose you've asked TeX to typeset an `S'. This will
eventually wind up in the Dvips output as the equivalent of this
PostScript operation:
(S) show
Here is how PostScript typesets the `S':
PostScript has a notion of "the current font"--whatever font is currently being typeset in.
Encoding
,
which defines the encoding vector (see Encodings) for that font.
This vector of 256 names maps each possible input character to a name.
/S
.
/S
as a key in a dictionary named
CharStrings
, another mandatory entry in a font dictionary.
S
in CharStrings
is the equivalent of a
series of standard PostScript commands like curveto
,
lineto
, fill
, and so on. These commands are executed to
draw the character. There can also be hint information that helps
adapt the character to low-resolution rasters. (See Glyph files.)
The commands are actually represented in a more compact way than
standard PostScript source; see the Type 1 book for details.
This method for typesetting characters is used in both Level 1 and Level 2 PostScript. See the PostScript reference manuals for more information.
To make a PostScript font available in a TeX document, you need to install the font on your system and then define it within the document. Once you have installed the font, of course, it is available for any document thereafter and you don't need to reinstall it. You must have an AFM file for any font you install. Unless the font is built into your printer, you must also have a PFA or PFB file.
In the following examples, we use the font Times-Roman
to
illustrate the process. But you should use the prebuilt fonts for Times
and the other standard fonts, rather than rebuilding them. The prebuilt
fonts are made using a more complicated process than that described
here, to make them work as well as possible with TeX. So following
the steps in this manual will not generate files identical to the
distributed ones. See PostScript font installation, for pointers to
the prebuilt fonts.
Installation of a PostScript font proceeds in three steps. See Font concepts, for descriptions of the various files involved.
afm2tfm
to create a TFM file for the original font,
and the VPL form of the virtual font:
afm2tfm Times-Roman -v ptmr rptmr
vptovf
to generate a VF and TFM file for the virtual font
from the VPL file:
vptovf ptmr.vpl ptmr.vf ptmr.tfm
psfonts.map
(See psfonts.map):
rptmr Times-Roman <ptmr8a.pfa
cp ptmr.vf fontdir/vf/... cp *ptmr.tfm fontdir/tfm/... cp ptmr.afm fontdir/afm/... cp ptmr.pf? fontdir/type1/...
The simplest invocation of Afm2tfm to make virtual fonts goes something like this:
afm2tfm Times-Roman -v ptmr rptmr
This reads the file Times-Roman.afm
, and produces two files as
output, namely the virtual property list'file ptmr.vpl
, and the
"raw" font metric file rptmr.tfm
. To use the font in TeX,
you first run
vptovf ptmr.vpl ptmr.vf ptmr.tfm
You should then install the virtual font file ptmr.vf
where Dvips
will see it and install ptmr.tfm
and rptmr.tfm
where
TeX and Dvips will see them.
Using these raw fonts is not recommended; there are no raw fonts in the
prebuilt PostScript fonts distributed along with Dvips. But
nevertheless, that's how Afm2tfm presently operates, so that's what we
document here. The r
prefix convention is likewise historical
accident.
You can also make more complex virtual fonts by editing ptmr.vpl
before running vptovf
; such editing might add the uppercase Greek
characters in the standard TeX positions, for instance. (This has
already been done for the prebuilt fonts.)
Once the files have been installed, you're all set. You can now do things like this in TeX:
\font\myfont = ptmr at 12pt \myfont Hello, I am being typeset in 12-point Times-Roman.
Thus, we have two fonts, one actual (rptmr
, which is analogous to
the font in the printer) and one virtual (ptmr
, which has been
remapped to the standard TeX encoding (almost)), and has typesetting
know-how added. You could also say
\font\raw = rptmr at 10pt
and typeset directly with that, but then you would have no ligatures or
kerning, and you would have to use Adobe character positions for special
letters like
the ligature `AE'.
The virtual font ptmr
not only has ligatures and kerning, and
most of the standard accent conventions of TeX, it also has a few
additional features not present in the Computer Modern fonts. For
example, it includes all the Adobe characters (such as the Polish ogonek
and the French guillemots). The only things you lose from ordinary
TeX text fonts are the dotless `j' (which can be hacked into the VPL
file with literal PostScript specials if you have the patience) and
uppercase Greek letters (which just don't exist unless you buy them
separately). See Reencoding with Afm2tfm.
As a final step you need to record information about both the virtual
font and the original font (if you ever might want to use it) in the
psfonts.map
file (see psfonts.map). For our example, you'd
insert the following into psfonts.map
:
rptmr Times-Roman <ptmr8a.pfa
Of course, Times-Roman
is already built in to most every
printer, so there's no need to download any Type 1 file for it. But if
you are actually following these instructions for new fonts, most likely
they are not built in to the printer.
These PostScript fonts can be scaled to any size. Go wild! Using
PostScript fonts, however, does use up a great deal of the printer's
memory and it does take time. You may find downloading bitmap fonts
(possibly compressed, with the Z
option) to be faster than using
the built-in PostScript fonts.
The Afm2tfm program converts an AFM file for a PostScript font to a TFM file and a VPL file for a corresponding virtual font (or, in its simplest form, to a TFM file for the PostScript font itself). The results of the conversion are affected by the command-line options and especially by the reencodings you can specify with those options. You can also obtain special effects such as an oblique font.
An alternative to Afm2tfm for creating virtual fonts is Alan Jeffrey's
fontinst
program, available from
CTAN:fonts/utilities/fontinst
(for CTAN info,
see unixtex.ftp).
Afm2tfm allows you to specify a different encoding for a PostScript font
(for a general introduction to encodings, see Encodings). The
-t
options changes the TeX encoding, -p
changes the
PostScript encoding, and -T
changes both simultaneously, as
detailed in the sections below.
-t
: Changing TeX encodingsTo build a virtual font with Afm2tfm, you specify the -v
or
-V
option. You can then specify an encoding for that virtual font
with -t tex-enc
. (-t
is ignored if neither
-v
nor -V
is present.) Any ligature and kerning
information you specify in tex-enc will be used in the VPL, in
addition to the ligature and kerning information from the AFM file.
If the AFM file has no entry for a character specified in tex-enc, that character will be omitted from the output VPL.
The -t
option is likely to be needed when you have a PostScript
font corresponding to a TeX font other than a normal text font such
as Computer Modern. For instance, if you have a PostScript font that
contains math symbols, you'd probably want to use the encoding in the
texmsym.enc
file supplied with Dvips. (For a start; to actually
get usable math fonts, you have to define much more than just an
encoding.)
-p
: Changing PostScript encodingsBy default, Afm2tfm uses the encoding it finds in the AFM file. You can
specify a different PostScript encoding with -p ps-enc
.
This makes the raw TFM file (the one output by Afm2tfm) have the
encoding specified in the encoding file ps-enc. Any ligature or
kern information specified in ps-enc is ignored by Afm2tfm, since
ligkern info is always omitted from the raw TFM.
If you use this option, you must also arrange to download ps-enc
as part of any document that uses this font. You do this by adding a
line like the following one to psfonts.map
(see psfonts.map):
zpopr Optima "MyEncoding ReEncodeFont" <myenc.enc
Using -p
is the only way to access characters in a PostScript
font that are neither encoded in the AFM file nor constructed from other
characters. For instance, Adobe's Times-Roman
font contains the
extra characters trademark
and registered
(among others);
these can only be accessed through such a PostScript reencoding.
In fact, the `8r' base encoding used for the current PostScript font
distribution (available at <ftp://ftp.tug.org/tex/psfonts.tar.gz
>)
does do this reencoding, for precisely this reason.
-T
: Changing both TeX and PostScript encodingsThe option -T enc-file
is equivalent to -p
enc-file -t enc-file
. If you make regular use of a private
non-standard reencoding -T
is usually a better idea than the
individual options, to avoid unexpected inconsistencies in mapping
otherwise. An example of when you might use this option is a dingbats
font: when you have a TeX encoding that is designed to be used with a
particular PostScript font.
The Afm2tfm program creates the TFM and VF files for the virtual font corresponding to a PostScript font by reencoding the PostScript font. Afm2tfm generates these files from two encodings: one for TeX and one for PostScript. The TeX encoding is used to map character numbers to character names while the PostScript encoding is used to map each character name to a possibly different number. In combination, you can get access to any character of a PostScript font at any position for TeX typesetting.
In the default case, when you specify none of the -t
, -p
,
or -T
options, Afm2tfm uses a default TeX encoding (which
mostly corresponds to the Computer Modern text fonts) and the PostScript
encoding found in the AFM file being read. The reencoding is also
sometimes called a remapping.
For example, the default encodings reencode the acute accent in two
steps: first the default TeX encoding maps the number 19 to the
character name acute
; then the default PostScript encoding, as
found in the AFM file for an ordinary PostScript font, maps the
character name acute
to the number 194. (The PostScript encoding
works in reverse, by looking in the encoding vector for the name and
then yielding the corresponding number.) The combined mapping of 19 to
194 shows up explicitly in the VF file and also implicitly in the fact
that the properties of PostScript character 194 appear in position 19 of
the TFM file for the virtual font.
The default encoding of the distributed fonts (e.g., ptmr.tfm
)
mostly follows plain TeX conventions for accents. The exceptions:
the Hungarian umlaut (which is at position 0x7D
in cmr10
,
but position 0xCD
in ptmr
); the dot accent (at positions
0x5F
and 0xC7
, respectively); and the Scandinavian A ring
\AA
, whose definition needs different tweaking. In order to use
these accents with PostScript fonts or in math mode when
\textfont0
is a PostScript font, you will need to use the
following definitions. These definitions will not work with the
Computer Modern fonts for the relevant accents. They are already part
of the distributed psfonts.sty
for use with LaTeX.
\def\H#1{{\accent"CD #1}} \def\.#1{{\accent"C7 #1}} \def\dot{\mathaccent"70C7 } \newdimen\aadimen \def\AA{\leavevmode\setbox0\hbox{h}\aadimen\ht0 \advance\aadimen-1ex\setbox0\hbox{A}\rlap{\raise.67\aadimen \hbox to \wd0{\hss\char'27\hss}}A}
As a kind of summary, here are the CODINGSCHEME
s that result from
the various possible choices for reencoding.
(CODINGSCHEME TeX text + AdobeStandardEncoding)
-p dc.enc
(CODINGSCHEME TeX text + DCEncoding)
-t dc.enc
(CODINGSCHEME DCEncoding + AdobeStandardEncoding)
-T dc.enc
(CODINGSCHEME DCEncoding + DCEncoding)
The CODINGSCHEME
line appears in the VPL file but is
ignored by Dvips.
Afm2tfm's encoding files have the same format as an encoding vector in a PostScript font. Here is a skeletal example:
% Comments are ignored, unless the first word after the percent sign % isLIGKERN
; see below. /MyEncoding [ % exactly 256 entries follow, each with a leading/
/Alpha /Beta /Gamma /Delta ... /A /B ... /Z ... /.notdef /xfooaccent /yfooaccent /zfooaccent ] def
These encoding files are downloaded as part of changing the encoding at the PostScript level (see the previous section).
Comments, which start with a percent sign and continue until the end
of the line, are ignored unless they start with LIGKERN
(see below).
The first non-comment word of the file must start with a forward slash
/
(i.e., a PostScript literal name) and defines the name of the
encoding. The next word must be an left bracket [
. Following
that must be precisely 256 character names; use /.notdef
for any
that you want to leave undefined. Then there must be a matching right
bracket ]
. A final def
token is optional. All names are
case-sensitive.
Any ligature or kern information is given as a comment. If the first
word after the %
is LIGKERN
, then the entire rest of the
line is parsed for ligature and kern information. This ligature and
kern information is given in groups of words: each group is terminated
by a space and a semicolon and (unless the semicolon is at the end of a
line) another space.
In these LIGKERN
statements, three types of information may be
specified. These three types are ligature pairs, kerns to ignore, and
the character value of this font's boundary character.
Throughout a LIGKERN
statement, the boundary character is
specified as ||
. To set the font's boundary character value for
TeX:
% LIGKERN || = 39 ;
To indicate a kern to remove, give the names of the two characters
(without the leading slash) separated by {}
, as in one
{} one ;
. This is intended to be reminiscent of the way you might
use {}
in a TeX file to turn off ligatures or kerns at a
particular location. Either or both of the character names can be given
as *
, which is a wild card matching any character; thus, all
kerns can be removed with * {} * ;
.
To specify a ligature, specify the names of the pair of characters,
followed by the ligature operation (as in Metafont), followed by the
replacing character name. Either (but not both) of the first two
characters can be ||
to indicate a word boundary.
The most common operation is =:
meaning that both characters are
removed and replaced by the third character, but by adding the |
character on either side of the =:
, you can retain either or both
of the two leading characters. In addition, by suffixing the ligature
operation with one or two >
signs, you can make the ligature
scanning operation skip that many resulting characters before
proceeding. This works just like in Metafont. For example, the `fi'
ligature is specified with f i =: fi ;
. A more convoluted
ligature is one one |=:|>> exclam ;
which separates a pair of
adjacent 1
's with an exclamation point, and then skips over two
of the resulting characters before continuing searching for ligatures
and kerns. You cannot give more >'s than |'s in an ligature
operation, so there are a total of eight possibilities:
=: |=: |=:> =:| =:|> |=:| |=:|> |=:|>>
The default set of ligatures and kerns built in to Afm2tfm is:
% LIGKERN question quoteleft =: questiondown ; % LIGKERN exclam quoteleft =: exclamdown ; % LIGKERN hyphen hyphen =: endash ; endash hyphen =: emdash ; % LIGKERN quoteleft quoteleft =: quotedblleft ; % LIGKERN quoteright quoteright =: quotedblright ; % LIGKERN space {} * ; * {} space ; 0 {} * ; * {} 0 ; % LIGKERN 1 {} * ; * {} 1 ; 2 {} * ; * {} 2 ; 3 {} * ; * {} 3 ; % LIGKERN 4 {} * ; * {} 4 ; 5 {} * ; * {} 5 ; 6 {} * ; * {} 6 ; % LIGKERN 7 {} * ; * {} 7 ; 8 {} * ; * {} 8 ; 9 {} * ; * {} 9 ;
Besides the reencodings described in the previous section, Afm2tfm can do other manipulations. (Again, it's best to use the prebuilt fonts rather than attempting to remake them.)

afm2tfm Times-Roman -s .167 -v ptmro rptmro
This creates ptmro.vpl
and rptmro.tfm
. To use this font,
put the line
rptmro Times-Roman ".167 SlantFont"
into psfonts.map
. Then rptmro
(our name for the obliqued
Times) will act as if it were a resident font, although it is actually
constructed from Times-Roman via the PostScript routine SlantFont
(which will slant everything 1/6 to the right, in this case).
Similarly, you can get an expanded font with
afm2tfm Times-Roman -e 1.2 -v ptmrre rptmrre
and by recording the pseudo-resident font
rptmrre Times-Roman "1.2 ExtendFont"
in psfonts.map
.
You can also create a small caps font with a command such as
afm2tfm Times-Roman -V ptmrc rptmrc
This will generate a set of pseudo-small caps mapped into the usual lowercase positions and scaled down to 0.8 of the normal cap dimensions. You can also specify the scaling as something other than the default 0.8:
afm2tfm Times-Roman -c 0.7 -V ptmrc rptmrc
It is unfortunately not possible to increase the width of the small caps independently of the rest of the font. If you want a really professional looking set of small caps, you need to acquire a small caps font.
To change the PaintType
in a font from filled (0) to outlined
(2), you can add "/PaintType 2 store"
to psfonts.map
, as
in the following:
rphvrl Helvetica "/PaintType 2 store"
Afm2tfm writes to standard output the line you need to add to
psfonts.map
to use that font, assuming the font is resident in
the printer; if the font is not resident, you must add the
<filename
command to download the font. Each identical
line only needs to be specified once in the psfonts.map
file,
even though many different fonts (small caps variants, or ones with
different output encodings) may be based on it.
Synopsis:
afm2tfm [option]... afmfile[.afm] [tfmfile[.tfm]]
Afm2tfm reads afmfile and writes a corresponding (but raw) TFM
file. If tfmfile is not supplied, the base name of the AFM file is
extended with .tfm
to get the output filename.
The simplest example:
afm2tfm Times-Roman rptmr
The TFM file thus created is raw because it omits ligature and
kern information, and does no character remapping; it simply contains
the character information in the AFM file in TFM form, which is the form
that TeX understands. The characters have the same code in the TFM
file as in the AFM file. For text fonts, this means printable ASCII
characters will work ok, but little else, because standard PostScript
fonts have a different encoding scheme than the one that plain TeX
expects (see Encodings). Although both schemes agree for the
printable ASCII characters, other characters such as ligatures and
accents vary. Thus, in practice, it's almost always desirable to create
a virtual font as well with the -v
or -V
option.
See Making a font available.
The command line options to Afm2tfm:
-c ratio
-V
; overrides the default ratio of 0.8 for the
scaling of small caps.
-e ratio
-O
vpl
file as octal numbers, not
names; this is useful for symbol or other special-purpose fonts where
character names such as A
have no meaning.

font obtained by scaling uppercase letters by 0.8 to typeset
lowercase. This font handles accented letters and retains proper
kerning.
psfonts.map
: PostScript font catalogThe psfonts.map
file associates a PostScript font with related
files and constructs. Each line has the format:
filename PostScript-name options
For example, the line
rpstrn StoneInformal <StoneInformal.pfb
causes Dvips to download StoneInformal.pfb
if your document (just
as if it were a header file, see Header files) uses the font
StoneInformal
.
If the j
config file or command-line option is enabled,
StoneInformal.pfb
will be partially downloaded--only those
characters your document actually uses will be extracted and downloaded,
and the remainder discarded. See Option details.
Filenames of fonts that are partially downloaded are surrounded by curly
braces ({...}
) in the progress report Dvips writes to
standard output. Wholly-downloaded fonts appear inside angle brackets
(<...>
), like other downloaded files.
Adobe Multiple Master fonts, such as Minion, cannot be partially
downloaded. To partially download in general, but avoid partial
downloading for individual fonts, use <<
instead <
:
pmnr8r Minion <<Minion.pfb
You can generate transformed fonts with a line like this:
rpstrc StoneInformal <StoneInformal.pfb ".8 ExtendFont"
See Special font effects, for a complete list of font effects.
You can change the encoding of the Type 1 font at the PostScript
level with a ReEncodeFont
instruction, plus the name of the
encoding file. This allows you access to characters that may be present
in the Type 1 font file, but not encoded by default--most of the
preaccented characters, for example. An example:
pstrn8r StoneInformal "TeXBase1Encoding ReEncodeFont" <8r.enc <pstrn8a.pfb
The 8r
encoding mentioned here has been designed to serve as a
base for all downloadable fonts; it allows access to all the characters
commonly present in a Type 1 font. For more details, see the
8r.enc
source file that comes with (and is installed with) Dvips.
You may notice that the same syntax is used for downloading encoding
vectors and Type 1 font files. To make your intentions clear, you can
also use <[
to explicitly indicate you are downloading an
encoding vector, as in:
pstrn8r StoneInformal "TeXBase1Encoding ReEncodeFont" <[8r.enc <pstrn8a.pfb
If the filename of your encoding vector does not end in .enc
, and
you are using partial font downloading, you must use the <[
syntax, or Dvips will not download the font properly.
Similarly, the name of the Type 1 font file itself must have extension
.pfa
or .pfb
for partial downloading to work properly.
When using PFB files, Dvips is smart enough to unpack the binary PFB format into printable ASCII so there is no need to perform this conversion yourself. In addition, Dvips scans the font to determine its memory usage, just as it does for other header files (see Header files).
Here is a brief summary of how psfonts.map
is read:
<<
, it is taken as a font file to be
wholly downloaded. Use this to avoid partial downloading, as described
above.
<[
, it is taken as an encoding file
to be downloaded. Use this if the name of the encoding file does end in
.enc
, also as described above.
<
character, it is
treated as a header file that needs to be downloaded. If the name ends
in .pfa
or .pfb
, it is taken as Type 1 font file that will
be partially downloaded if the j
option is in effect. There can
be more than one such header for a given font. If a <
is a word
by itself, the next word is taken as the name of the header file.
"
character, it is taken as PostScript
code used in generating that font, and is inserted into the output
verbatim at the appropriate point. (And the double quotes beginning and
ending the word are removed.)
Dvips supports one-pass multi-color printing of TeX documents on any
color PostScript device. Initially added by Jim Hafner, IBM Research,
hafner@almaden.ibm.com, the color support has gone through many
changes by Tomas Rokicki. Besides the source code support itself, there
are additional TeX macro files: colordvi.tex
and
blackdvi.tex
, and corresponding .sty
versions for use with
LaTeX.
In this section we describe the use of color from the document preparer's point of view and then add some instructions on installation for the TeX administrator.
All the color macro commands are defined in colordvi.tex
(or
colordvi.sty
). To access these macros simply add to the top of
your plain TeX file the command:
\input colordvi
For (the obsolete) LaTeX 2.09, add the colordvi
style option as in:
\documentstyle[12pt,colordvi]{article}
For LaTeX 2e, these examples are not applicable. Instead, please see
the documentation for the graphics package, available from
CTAN:doc/latex/graphics/
. See also
CTAN:doc/epslatex.ps
.
These macros provide two basic kinds of color macros: ones for local
color changes (a few words, a single symbol) and one for global color
changes (the whole document). All the color names use a mixed case
scheme to avoid conflicts with other macros. There are 68 predefined
colors, with names taken primarily from the Crayola crayon box of 64
colors, and one pair of macros for the user to set his own color pattern
(see User-definable colors). You can browse the file
colordvi.tex
for a list of the predefined colors. The comments
in this file also show a rough correspondence between the crayon names
and Pantones.
A local color command has the form
\ColorName{this is the color ColorName}
where ColorName is the name of a predefined color, e.g.,
Blue
. As shown, these macros take one argument, the text to
print in the specified color. This can be used for nested color changes
since it restores the original color state when it completes. For
example:
This text is normal but here we are \Red{switching to red, \Blue{nesting blue}, recovering the red} and back to original.
The color nesting level has no hard limit, but it is not advisable to nest too deeply lest you and the reader lose track of the color history.
The global color command has the form
\textColorName
These macros take no arguments and changes the default color from that point on to ColorName. This of course can be overridden globally by another such command or locally by local color commands. For example, expanding on the example above, we might have
\textGreen This text is green but here we are \Red{switching to red, \Blue{nesting blue}, recovering the red} and back to original green. \textCyan The text from here on will be cyan until \Yellow{locally changed to yellow}. Now we are back to cyan.
The color commands will even work in math mode and across math mode
boundaries. This means that if you have a color before going into math
mode, the mathematics will be set in that color as well. In alignment
environments like \halign
, tabular
or eqnarray
,
local color commands cannot extend beyond the alignment characters.
Because local color commands respect only some environment and delimiter changes besides their own, care must be taken in setting their scope. It is best not to have them stretch too far.
At the present time there are no macros for color environments in LaTeX which might have a larger range. This is primarily to keep the TeX and LaTeX use compatible.
There are two ways for the user to specify colors not already defined.
For local changes, there is the command \Color
which takes two
arguments. The first argument is four numbers between zero and one and
specifies the intensity of cyan, magenta, yellow and black (CMYK) in
that order. The second argument is the text that should appear in the
given color. For example, suppose you want the words "this color is
pretty" to appear in a color which is 50% cyan, 85% magenta, 40% yellow
and 20% black. You would use the command
\Color{.5 .85 .4 .2}{this color is pretty}
For global color changes, there is a command \textColor
which
takes one argument, the CMYK quadruple of relative color intensities.
For example, if you want the default color to be as above, then the
command
\textColor{.5 .85 .4 .2} The text from now on will be this pretty color
will do the trick.
Making a global color change in the midst of nested local colors is highly discouraged. Consequently, Dvips will give you warning message and do its best to recover by discarding the current color history.
Color macros are defined via \special
keywords. As such, they
are put in the .dvi
file only as explicit message strings to the
driver. The (unpleasant) result is that certain unprotected regions of
the text can have unwanted color side effects. For example, if a color
region is split by TeX across a page boundary, then the footers of
the current page (e.g., the page number) and the headers of the next
page can inherit that color. To avoid this effect globally, users
should make sure that these special regions of the text are defined with
their own local color commands. For example, to protect the
header and footer in plain TeX, use
\headline{\Black{My Header}} \footline{\Black{\hss\tenrm\folio\hss}}
This warning also applies to figures and other insertions, so be careful!
Of course, in LaTeX, this is much more difficult to do because of the complexity of the macros that control these regions. This is unfortunate but inevitable, because TeX and LaTeX were not written with color in mind.
Even when writing your own macros, much care must be taken. The macros
that `colorize' a portion of the text work prefix the text work by
outputting one \special
command to turn the color on before the
text, and outputting another \special
command afterwards to
restore the original color. It is often useful to ensure that TeX is
in horizontal mode before the first special command is issued; this can
be done by prefixing the color command with \leavevmode
.
If you have a TeX or LaTeX document written with color macros and
you want to print it in black and white there are two options. On all
(good) PostScript devices, printing a color file will print in
corresponding gray levels. This is useful to get a rough idea of the
colors without using expensive color printing devices. The second
option is to replace the call to input colordvi.tex
with
blackdvi.tex
(and similarly for the .sty
files). So in
the above example, replacing the word colordvi
with
blackdvi
suffices. blackdvi.tex
defines the color macros
as no-ops, and so will produce normal black/white printing. By this
simple mechanism, the user can switch to all black/white printing
without having to ferret out the color commands. Also, some device
drivers, particularly non-PostScript ones like screen previewers, will
simply ignore the color commands and so print in black/white.
Hopefully, in the future screen previewers for color displays will be
compatible with some form of color support.
To configure Dvips for a particular color device you need to fine tune
the color parameters to match your device's color rendition. To do this,
you will need a Pantone chart for your device. The header file
color.lpro
shows a (rough) correspondence between the Crayola
crayon names and the Pantone numbers and also defines default CMYK
values for each of the colors. Note that these colors must be defined
in CMYK terms and not RGB, as Dvips outputs PostScript color commands in
CMYK. This header file also defines (if they are not known to the
interpreter) the PostScript commands setcmykcolor
and
currentcmykcolor
in terms of a RGB equivalent so if your device
only understands RGB, there should be no problem.
The parameters set in this file were determined by comparing the Pantone
chart of a Tektronix Phaser printer with the actual Crayola Crayons.
Because these were defined for a particular device, the actual color
rendition on your device may be very different. There are two ways to
adjust this. One is to use the PAntone chart for your device to rewrite
color.lpro
prior to compilation and installation. A better
alternative, which supports multiple devices, is to add a header file
option in the configuration file (see Configuration file commands)
for each device that defines, in userdict
, the color parameters
for those colors that need redefining.
For example, if you need to change the parameters defining
Goldenrod
(approximately Pantone 109 on the Phaser) for your
device mycolordev
, do the following. In the Pantone chart for
your device, find the CMYK values for Pantone 109. Let's say they are
{\ 0 0.10 0.75 0.03 }
. Then create a header file named
mycolordev.pro
with the commands
userdict begin /Goldenrod { 0 0.10 0.75 0.03 setcmykcolor} bind def
Finally, in config.mycolordev
add the line
h mycolordev.pro
This will then define Goldenrod
in your device's CMYK values in
userdict
which is checked before defining it in TeXdict
by
color.pro
. (On MS-DOS, you will have to call this file
mycolordev.cfg
.)
This mechanism, together with additions to colordvi.tex
and
blackdvi.tex
(and the .sty
files), can also be used to
predefine other colors for your users.
To support color, Dvips recognizes a certain set of specials. These
specials start with the keyword color
or the keyword
background
, followed by a color specification.
What is a color specification? One of three things. First, it might be
a PostScript procedure as defined in a PostScript header file. The
color.pro
file defines 64 of these, including Maroon
.
This PostScript procedure must set the current color to be some value;
in this case, Maroon
is defined as 0 0.87 0.68 0.32
setcmykcolor
.
The second possibility is the name of a color model (initially, one of
rgb
, hsb
, cmyk
, or gray
) followed by the
appropriate number of parameters. When Dvips encounters such a macro,
it sends out the parameters first, followed by the string created by
prefixing TeXcolor
to the color model. Thus, the color
specification rgb 0.3 0.4 0.5
would generate the PostScript code
0.3 0.4 0.5 TeXrgbcolor
. Note that the case of zero arguments is
disallowed, as that is handled by the single keyword case
(Maroon
) above, where no changes to the name are made before it
is sent to the PostScript file.
The third and final type of color specification is a double quote
followed by any sequence of PostScript. The double quote is stripped
from the output. For instance, the color specification
"AggiePattern setpattern
will set the `color' to the Aggie logo
pattern (assuming such exists.)
We will describe background
first, since it is the simplest. The
background
keyword must be followed by a color specification.
That color specification is used as a fill color for the background.
The last background
special on a page is the one that gets
issued, and it gets issued at the very beginning of the page, before any
text or specials are sent. (This is possible because the prescan phase
of Dvips notices all of the color specials so that the appropriate
information can be written out during the second phase.)
The color
special itself has three forms.
The first is just color
followed by a color specification. In
this case, the current global color is set to that color; the color stack
must be empty when such a command is executed.
The second form is color push
followed by a color specification.
This saves the current color on the color stack and sets the color to be
that given by the color specification. This is the most common way to
set a color.
The final version of the color
special is just color pop
,
with no color specification; this says to pop the color last pushed on
the color stack from the color stack and set the current color to be
that color.
Dvips correctly handles these color specials across pages, even when the pages are repeated or reversed.
These color specials can be used for things such as patterns or screens
as well as simple colors. However, note that in the PostScript, only
one color specification can be active at a time. For instance, at the
beginning of a page, only the bottommost entry on the color stack is
sent; also, when a color is popped, all that is done is that the color
specification from the previous stack entry is sent. No gsave
or
grestore
is used. This means that you cannot easily mix usage of
the color
specials for screens and colors, just one or the other.
This may be addressed in the future by adding support for different
categories of color-like state.
