NAME
ps2pk - creates a TeX pkfont from a type1 PostScript font
SYNOPSIS
ps2pk [ -v ] [ -eenc ] [ -Xxres ] [ -Eexpansion ] [ -Sslant ] [ -Ppointsize ] [ -Rbaseres ] [
-raspectratio ] [ -Yyres ] [ -aAFMfile ] [ -mmodename ] type1 [pkfont]
DESCRIPTION
This program renders a given type1 PostScript font at a given pointsize (default 10.0 points) and
resolution (default 300dpi) into a TeX pkfont.
To generate the pkfont ps2pk needs a valid type1 font file (for example Utopia-Regular, Utopia-Regula.pfb
or Utopia-Regula.pfa) and its corresponding AFM-file (Utopia-Regular.afm) with the font metrics. The
program accepts both the binary type1 format (Utopia-Regula.pfb) and its ASCII equivalent (Utopia-Regular
or Utopia-Regula.pfa). To locate the files, ps2pk uses the kpathsea library (see the info page on
kpathsea). Additionally, pfb and pfa files are searched for in the directory specified in the environment
variable T1INPUTS, and afm files are searched in AFMFONTS, if they are set (the -v flag will report which
filenames are looked for).
The program will make a pkfont in which the character codes are derived from their AFM (Adobe Font
Metrics) defined values. This can be overruled by specifying an explicit encoding file via the -e
option. The encoding file enc should contain a valid PostScript encoding containing PostScript names
like /hyphen. Here is an incomplete example (see afm2tfm for complete syntax):
% This is the EC encoding.
/ECEncoding [ % now 256 chars follow
% 0x00
/grave /acute /circumflex /tilde /dieresis /hungarumlaut
/ring /caron /breve /macron /dotaccent /cedilla
/ogonek /quotesinglbase /guilsinglleft /guilsinglright
(Rest of lines omitted.)
% 0xF0
/eth /ntilde /ograve /oacute /ocircumflex /otilde
/odieresis /oe /oslash /ugrave /uacute /ucircumflex
/udieresis /yacute /thorn /germandbls ] def
Options and arguments:
-aAFMfile Overrules the name that is used to locate the AFM file.
-eenc Name of a file containing an encoding scheme (default - the encoding named in the AFM-file is
used). The actual PostScript name of the encoding scheme is written as a "special" at the
end of the pkfont.
-Eextension The extension factor (real value, default 1.0).
-mmodename A modename such as would be used by METAFONT (default "Unknown mode").
-Ppointsize The desired pointsize (real value, default 10.0 points).
-Rbaseres The desired base resolution (integer value, default 300 dpi). If this differs from the value
of xres, the appropriate magnification will be shown in the "specials" at the end of the
pkfont. If possible, this will be expressed as a magstep, otherwise as a real number. For
example, a pkfont with an xres of 329, using the default base resolution of 300, will include
the "special" text "mag=magstep(0.5)" at the end of the font.
-raspectratio
The desired aspect ratio (expression, integerY/integerX, default 300/300). This will be
shown in the "specials" at the end of the pkfont. Setting the aspect ratio creates a value
for yres but an explicit yres value will take precedence. Argument must be in "" if spaces
are left around `/'.
-Sslant The slant (real value, default 0.0).
-Xxres The resolution in the X direction (integer value, default 300 dpi).
-Yyres The resolution in the Y direction (integer value, default the value of xres). If yres differs
from xres, a "special" text giving the aspect ratio will be written at the end of the pkfont.
-v Verbose flag. (Tells what the program is doing.)
type1 The name of the PostScript type1 font. The name of the AFM-file will be constructed from
this name by removing the extension (if supplied) and adding ".afm". The PostScript
"FontName" is extracted from the AFM-file and written into a "special" at the end of the
pkfont.
[pkfont] The name of the resulting pkfont can be overruled with this name. The default name of pkfont
is derived from the basename of the type1 font, the pointsize and xres. For example `ps2pk
-P17.28 Utopia-Regular' will result in `Utopia-Regular17.300pk'. An explicit value for the
name of the pkfont is necessary when the type1 font name already shows the point size,
otherwise the pointsize value is catenated on to the pkfont basename which is usually not
what is wanted.
The following PK "specials" provide an internal check on the characteristics of the pkfont, in accordance
with the recommendations of the TeX Working Group on the TeX Directory Standard (TWG-TDS):
"fontid=FontName", "codingscheme=Encoding", "fontfacebyte", "mag", "mode=(ps2pk)modename", "pixels-per-
inch", and "aspect-ratio" if it is other than unity.
