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
        } |-
