## 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-read‐
       able 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**
