PS2PK(1) PS2PK(1)
NAME
ps2pk - creates a TeX pkfont from a type1 PostScript font
SYNOPSIS
pk2pk [ options] type1 [pkfont]
options: -v -eenc -Xxres -Eexpansion -Sslant
options: -Ppointsize -Rbaseres -raspectratio
options: -Yyres -aAFMfile -mmodename
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 pk2ps needs a valid type1 fontname (for example
Utopia-Regular, Utopia-Regula.pfb or Utopia-Regula.pfa) and its corre-
sponding AFM-file (Utopia-Regular.afm). The program accepts both the
MSDOS binary type1 format (Utopia-Regula.pfb) and its ASCII equivalent
(Utopia-Regular or Utopia-Regula.pfa). To locate the type1 font and
its AFM-file ps2pk will use the environment T1INPUTS if it is set oth-
erwise its built in default (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 over-
ruled 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 appro-
priate 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 prece-
dence. 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 suplied) 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 base-
name of the type1 font, the pointsize and xres. For exam-
ple `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 character-
istics 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.

This program uses the type1 hinting and rendering software IBM has
donated to the X-consortium.
