t1disasm(1)


NAME

   t1disasm - disassemble PostScript Type 1 font

SYNOPSIS

   t1disasm [input [output]]

DESCRIPTION

   t1disasm  disassembles  Adobe  Type  1  font  programs  in  either  PFA
   (hexadecimal) or PFB (binary) formats into human-readable form. If  the
   file  output  is  not specified output goes to the standard output.  If
   the file input is not specified input comes from the standard input.

   t1disasm performs eexec and charstring decryption as specified  in  the
   ``black book'', Adobe Type 1 Font Format.  Additionally, the charstring
   binary tokens are expanded into human-readable  text  form,  using  the
   names  given  in  the  black book and later documents describing Type 2
   opcodes.

EXAMPLES

   % t1disasm Utopia-Regular.pfb Utopia-Regular.raw
   % t1disasm Utopia-Regular.pfa Utopia-Regular.raw

   In Subrs entries in Utopia-Regular.raw will look like
          dup 5 {
                  8 111 vstem
                  -12 128 hstem
                  707 -20 hstem
                  return
                  } |
   and the CharStrings entries like
          /exclam {
                  58 242 hsbw
                  6 callsubr
                  5 4 callsubr
                  63 707 rmoveto
                  -54 0 -5 -22 4 -45 rrcurveto
                  40 -431 rlineto
                  29 hlineto
                  42 431 rlineto
                  4 45 -5 22 -55 0 rrcurveto
                  closepath
                  6 4 callsubr
                  -719 vmoveto
                  243 callsubr
                  endchar
                  } |-
