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.
-
--pfa, -a
- Output in PFA (ASCII) format.
-
--pfb, -b
- Output in PFB (binary) format. This is the default.
-
--block-length=num, -l num
- PFB only: Set the maximum output block length to
num. The default length is as large as memory allows.
-
--line-length=num, -l num
- PFA only: Set the maximum length of encrypted lines in the
output to num. (These are the lines consisting wholly of
hexadecimal digits.) The default is 64.

The Type 2 Charstring Format, also available from Adobe as a PDF file,
describes the newer Type 2 operators, which are also used in some
multiple-master Type 1 fonts like Adobe Jenson and Kepler.
