MAG(1) General Commands Manual MAG(1)NAME
mag - computes fontsizes and magsteps
SYNOPSIS
mag [-Rdpi] magstep . . .
mag [-r] [-Rdpi] fontsize . . .
DESCRIPTION
delim $$ This tool calculates fontsizes given magsteps. TeXfonts are provided as true sized fonts or as magnifications. The fontsize of a
true sized font equals the resolution of the printer (ex. 300). The fontsize of a font magnified $n$ magsteps equals: 1.2 sup{n} times
300 delim off rounded to its nearest integer value. Fontnames for TeX fonts normally consists of the name (cmr), pointsize (10), type (pk)
and fontsize (360), for example: cmr10.360pk.
EXAMPLES
The result of mag -R240 -2 0 0.5 1 will be:
167 240 263 288
The inverse function is computed with the -r option. The result of mag -r -R240 167 240 263 288 will be the fontsteps:
-2 0 0.5 1
The UNIX shells allow command substitution. One can write:
mag -r -R240 `mag -R240 -2 0 0.5 1`

PS2PK(1) General Commands Manual 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 cor-
responding AFM-file (Utopia-Regular.afm). The program accepts both the MSDOS binary type1 format (Utopia-Regula.pfb) and its ASCII equiva-
lent (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
otherwise 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
overruled by specifying an explicit encoding file via the -e option. The encoding file enc should contain a valid PostScript encoding con-
taining 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 magnifi-
cation 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 giv-
ing 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 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.

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