.TH PS2PK 1 "30 August 2022"
.SH NAME
ps2pk \- creates a TeX pkfont from a type1 PostScript font
.SH SYNOPSIS
ps2pk
[ -v ]

[ -E\fIexpansion\fP ]
[ -S\fIslant\fP ]

[ -m\fImodename\fP ]
type1 [pkfont]
.SH 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.
.PP
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).
.PP
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 \fIenc\fP
should contain a valid PostScript encoding containing PostScript names
like /hyphen. Here is an incomplete example (see afm2tfm for complete
syntax):
.RS
.nf
% 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
.fi
.RE
.PP
Options and arguments:
.IP -a\fIAFMfile\fP 12
Overrules the name that is used to locate the AFM file.
.IP -e\fIenc\fP 12
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.
.IP -E\fIextension\fP 12
The extension factor (real value, default 1.0).
.IP -m\fImodename\fP 12
A modename such as would be used by METAFONT (default "Unknown mode").
.IP -P\fIpointsize\fP 12
The desired pointsize (real value, default 10.0 points).
.IP -R\fIbaseres\fP 12
The desired base resolution (integer value, default 300 dpi).
If this differs from the value of \fIxres\fP, 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 \fIxres\fP
of 329, using the default base resolution of 300,
will include the "special" text "mag=magstep(0.5)" at the
end of the font.
.IP -r\fIaspectratio\fP 12
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
\fIyres\fP but an explicit \fIyres\fP value will take precedence.
Argument must be in "" if spaces are left around `/'.
.IP -S\fIslant\fP 12
The slant (real value, default 0.0).
.IP -X\fIxres\fP 12
The resolution in the X direction (integer value, default 300 dpi).
.IP -Y\fIyres\fP 12
The resolution in the Y direction (integer value, default the value
of \fIxres\fP). If \fIyres\fP differs from \fIxres\fP, a "special"
text giving the aspect ratio will be written at the end of the
pkfont.
.IP -v 12
Verbose flag. (Tells what the program is doing.)
.IP type1 12
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.
.IP [pkfont] 12
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 \fIxres\fP. 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 \fIpointsize\fP value is catenated on to the pkfont basename
which is usually not what is wanted.
.PP
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):
.br
"fontid=\fIFontName\fP", "codingscheme=\fIEncoding\fP", "fontfacebyte", "mag",
"mode=(ps2pk)\fImodename\fP", "pixels-per-inch", and "aspect-ratio" if it
is other than unity.
.SH ACKNOWLEDGEMENT
This program uses the Type1 hinting and rendering software IBM
has donated to the X Consortium.
