I have received many requests for software that allows including Macintosh
and other PostScript illustrations in TeX output. So here it comes, in
3 parts.
dvi2ps.c A translator from TeX dvi output to PostScript. This version
fixes trivial bugs (use of tolower under Berkeley) and trivial
changes in the processing of \special inclusions. I've included
it in its entirety because of popular demand.
findfile.c
findfile.h
commands.h all used by above.
Makefile cheapo version
dvi2ps.1 n/troff version of the man page, courtesy bur@iro.udem.cdn
tex.ps The header file used by dvi2ps. This version modified to
be more portable and to behave itself properly wrt PostScript
illustrations. Overrides some definitions from the LaserPrep
file below.
LaserPrep.uu uuencoded version of LaserPrep.ps The header file needed for
Macintosh illustrations, with all the patches that made it here.
I have broken so many mailers and it has been damaged by so many
other mailers that I had to choose that route.
Bugs you don't report won't get fixed.
In the queue: including troff preprocessor (pic, grap, S, ideal, ...) output
in TeX documents, and posting the software we have here for doing inclusions
in troff documents.

.SH DESCRIPTION
This program converts a DVI file to PostScript, and writes the result
to standard output. The result requires a small amount of PostScript
source to precede it to the printer, before it can be successfully printed.
(By default, that PostScript code is prepended to the output.)
.SH OPTIONS
.IP "\fB\-a \fIpxldir"
specify different area for PXL files.
Directory
.I pxldir
is searched
for all PXL files, instead of the default directory.
.IP \fB\-c
create an output file in the spool directory.
This is fairly Apollo-specific, and may be disabled at other
sites. When given, the output is directed to a file with
a unique name, created in a spool directory.
.IP \fB\-d
select debugging output (you probably don't want to).
.IP "\fB\-f \fIn"
specify a starting page number
(this is a TeX page number \- \\count0).
.IP \fB\-h
do not copy the standard header file.
This option prevents the standard PostScript header file being
prepended to the output.
.IP "\fB\-i \fIfile"
copy the named file to the output.
The contents of the file named will be copied to the output
after the standard header file has been copied.
.TP
\fB\-m0\fP | \fB\-mh\fP | \fB\-m1\fP | \fB\-m2\fP | \fB\-m3\fP | \fB\-m4\fP
specify a magstep to use to print the document. This overrides
whatever might be in the DVI file.
.IP "\fB\-m \fIn"
specify a magnification to use to print the document. This should
probably be one of the magic numbers 1000, 1095, 1200, 1440, 1728,
or 2074, but no checking is done. Note: if your site does not have the
complete set of 300 dpi fonts, this option might be disabled.
.IP "\fB\-n \fIn"
specify the number of copies to print.
.IP "\fB\-o \fIstr"
specify a printing option.
Valid options are
.BR letter ,
.BR note ,
.BR legal ,
.BR landscape ,
.BR envelope ,
and
.BR manualfeed .
This argument may be repeated several times.
.B envelope
is a variant of
.B landscape
that selects manual feed and does proper positioning for regular envelopes.
.IP \fB\-p
do not preload font information.
Occasionally there may be insufficent memory to hold the
information about all of the fonts in the system. Portions
of the document may be converted by including the
.B \-p
option on the command line. This will prevent the preloading of
all fonts into the system and instead use demand loading of
the font tables.
.IP \fB\-q
be quiet.
Don't chatter about pages converted, etc.
.IP \fB\-r
stack pages in reverse order.
Normally, the DVI pages are processed in reverse order, with the
result that they are stacked in the correct order in the output
tray. This option reverses that.
.IP \fB\-s
turn on printing of statistics.
Some versions of
.I dvi2ps
will optionally print statistics about
font usage and some other information that is generally only
interesting to developers. On these systems,
.B \-s
turns on
the statistics printing.
.IP "\fB\-t \fIn"
specify an ending page number.
.IP \fB\-w
Don't print out warnings.
.SH NOTES
This is a `bare bones' DVI-to-PostScript program. Minimal error
checking is done.
Not all fonts are available in the resolution needed to display on the
laser printer; when a missing font is encountered,
.I dvi2ps
will continue
to process your DVI file, and will log a warning message. Gaps will
appear in the document where the missing characters should have been.
It can take up to 60 seconds for the first page to be output. After a
head of steam has been built up, it can roll along at 5-10 seconds
per page.
.SH PostScript ILLUSTRATIONS
This program supports use of the \fB\\special\fP command in TeX to include
special PostScript code for graphics, etc. Specifying
\fB\\special{psfile=foo.ps}\fP in the TeX source will result in the contents
of file
.I foo.ps
(assumed to contain PostScript code) being copied
into the output at that point. For most included graphics, the
user's (0,0) point will be set to the point of the \fB\\special\fP command
with
.I x
and
.I y
coordinates increasing up and to the right and in units
of PostScript points (72/inch) \(em thus you must explicitly leave space
above the \fB\\special\fP command for most graphics. For graphics produced by
Apple Macintoshes (i.e., MacDraw, MacPaint, etc.), the top left corner of
the drawing will be at the point of the \fB\\special\fP command; in this case
you must leave the required space below the \fB\\special\fP.
The \fB\\special\fP string can contain any number of the following
.I keyword=value
pairs, separated by blanks:
.ta 10n
.TP 24n
\fIKeyword Value Type
(dimensions in points: 72 pt = 1 in)
.TP
psfile string
\- PostScript file to include
.PD 0
.TP
hsize dimension
\- maximum horizontal size (for clipping)
.TP
vsize dimension
\- maximum vertical size (for clipping). Use negative values to specify a
clipping region below the current position.
.TP
hoffset dimension
\- amount to shift right
.TP
voffset dimension
\- amount to shift up
.TP
hscale number
\- scale factor in x-dimension
.TP
vscale number
\- scale factor in y-dimension
.TP
rotation number
\- counter-clockwise rotation angle
.PD
.DT
.PP
Thus:
.ce
\fB\\special{psfile=foo.ps hoffset=72 hscale=0.9 vscale=0.9}\fP
will shift the graphics produced by file
.I foo.ps
right by
1", and will draw it at 0.9 normal size.
.B hsize
and
.B vsize
are given relative to the (0,0) point of the
drawing and are unaffected by offsets and scales.
Offsets are given relative to the point of the \fB\\special\fP command,
and are unaffected by scales.
If Macintosh drawings are to be included, the proper LaserPrep file
must be downloaded to the printer, either permanently or as another
header file in addition to the standard
.I tex.ps
header file.

.SH BUGS
There is likely a limit to the size of documents that can be printed (at
least, on the Apple LaserWriter). If you get VMerrors reported when
printing, use the
.B \-f
and
.B \-t
options, to select a range of pages.
The exact limit is unknown, but is probably well in excess of 50 pages
for `normal' documents, decreasing with number of different fonts used,
size of fonts, etc.
.SH AUTHORS
Mark Senn wrote the early versions of this program for the
BBN BitGraph. Stephan Bechtolsheim, Bob Brown, Richard
Furuta, James Schaad and Robert Wells improved it. Norm
Hutchinson ported the program to the Sun. Neal Holtz ported
it to the Apollo, and then to produce PostScript.
Scott Jones added intelligent font substitution.
Jean-Francois Lamy fixed the interface for PostScript illustrations.

#define VERSION "2.11"
/* $Header: dvi2ps.c,v 1.3 86/11/27 13:55:03 lamy Exp $
*
* AUTHOR(s)
* Mark Senn wrote the early versions of this program for the
* BBN BitGraph. Stephan Bechtolsheim, Bob Brown, Richard
* Furuta, James Schaad and Robert Wells improved it. Norm
* Hutchinson ported the program to the Sun. Neal Holtz ported
* it to the Apollo, and from there to producing PostScript
* output. Scott Jones added intelligent font substitution.
* Jean-Francois Lamy fixed the PostScript interface for illustrations.
*
*/
/* Basic method:
* Using the local font cacheing machinery that was in the previewer,
* we can easily manage to send the bitmap for each chracter only once.
* Two passes are made over each page in the DVI file. The first pass
* simply outputs the bitmaps for all characters on that page that haven't
* been sent before. The second pass outputs all the character setting
* and positioning commands. This allows us to bracket the setting portion
* with PostScript save's and restore's, thus reclaiming considerable
* virtual memory after each page.
*
* All coordinates are output in the PostScript system (TeX origin),
* and in integer units of rasters (300/inch) -- except for character
* widths, which are sent as floating point numbers.
*
* About 2 pages of PostScript support code must be sent to the LaserWriter
* before this stuff goes. It is automatically included unless the
* -h option is given.
*/
/* Change log:
*
* Early 1985, (nmh) -- ported sun version to Apollo.
* A little later (nmh) -- changed to continue on in the event of missing
* font files.
* 30-Mar-85 (nmh) -- added -a option to specify a different PXL area
* 30-Mar-85 (nmh) -- changed default PXL area to /pxl118
* 31-Mar-85 (nmh) -- fixed bug in OpenFontFile() regarding more than MAXOPEN
* PXL files -- changed to mark files as closed in font_entry.
* 7-Apr-85 (nmh) -- made command line argument decoding case insensitive.
* cleaned up handling of DVI file name argument.
* 30-May-85 (nmh) -- new version; hacked to output PostScript commands
* 6-Jun-85 (nmh) -- added relative positioning (20% smaller PostScript output)
* add -m option to specify mag
* 11-Jun-85 (nmh) -- fixed bug regarding char spacings in very long "words"
* 12-Jun-85 (nmh) -- v1.02 - process DVI pages in reverse order
* 13-Jun-85 (nmh) -- fixed bug re PXL files getting opened too often when no PreLoad
* 14-Jun-85 (nmh) -- font dict created in PostScript only when 1st char of font downloaded
* add -m0 -mh -m1 etc. to specify magsteps
* 16-Aug-85 (nmh) -- added -c option t0 create output file in spool area (Apollo specific)
* added -h option to copy header file to output
* added -o option to pass options through to PostScript
* 20-Aug-85 (nmh) -- v1.03
* 24-Aug-85 (nmh) -- add -q option (for quiet operation).
* changed -o option to check PostScript option
* changed to output coordinates in TeX system (but
* scaled to raster units) -- (0,0) at 1" in and down from
* top left (better for use with different size paper).
* -- v2.00
* 25-Aug-85 (nmh) -- added dictionary enclosure to Tex.ps, and output
* suitable prolog here.
* 26-Aug-85 (nmh) -- changes to tex.ps to support Macintosh documents.
* 14-Sep-85 (nmh) -- added keyword=value decoding to \special;
* 15-Sep-85 (nmh) -- added -i file option.
* 23-Sep-85 (saj) -- added font substitution for case when font is
* unavailable at requested mag. (a frequent occurrence
* with some macro packages like LaTeX)
* 24-Jun-86 (jfl) -- Support Mac illustrations produced by LaserWriter
* driver 3.0 Changed tex.ps
* Added rotation for \special inclusions
* Embedded ^D are ignored in included PostScript files
