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   corresponding   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 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   containing
     PostScript  names like /hyphen.  Here is an incomplete exam-
     ple (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  encod-
                 ing  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 exam-
                 ple, 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 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  over-
                 ruled  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 recom-
     mendations 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.


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