## 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**
