T1ASM(1)

NAME
t1asm - assemble type-1 font

SYNOPSIS
t1asm [ -a ] [ -b ] [ -l length ] [ input [ output ] ]

DESCRIPTION
t1asm assembles Adobe Type 1 font programs into either PFA (hexadecimal) or PFB (binary) formats from a 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. t1asm tokenizes the charstring data and performs eexec and charstring encryption as specified in the ``black book,'' Adobe Type 1 Font Format. The input must have a line of the form
    /-|{string currentfile exch readstring pop}executeonly def
which defines the command, in this case `-|', that is to start charstring data. It is an error not to define such a command. Another common name for this command is `RD'. After the start of the Subrs array in the input, all open braces `{' not in a comment begin a charstring. Such a charstring is terminated by the next non-comment close brace `}'. Within such a charstring, only comments, integers, and valid charstring commands are allowed. Valid charstring command names can be found in Adobe Type 1 Font Format and other documents describing the newer Type 2 opcodes. The format within a charstring is unimportant as long as integers and commands are separated by at least a one whitespace (space, tab, newline) character. Note that within charstrings, comments are discarded because they cannot be encoded.

OPTIONS

--pfa, -a
    Output in PFA (ASCII) format.

--pfb, -b
    Output in PFB (binary) format. This is the default.

--block-length=num, -l num
    Set the maximum length of sections in PFB output to length. The default value is large, 2**17 - 6, yielding a section size, including section header, of 128 Kbytes. This default value is also the maximum allowable length.

EXAMPLES

% t1asm Utopia-Regular.raw Utopia-Regular.pfb
% t1asm -a Utopia-Regular.raw Utopia-Regular.pfa
