T1ASM(1)T1ASM(1)NAMEt1asm - assemble type-1 font
SYNOPSISt1asm [-a|-b] [-l length] [input [output]]
DESCRIPTIONt1asm assembles Adobe Type 1 font programs into either PFA
(hexadecimal) or PFB (binary) formats from a human-read
able 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, inte
gers, 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
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 consist
ing wholly of hexadecimal digits.) The default is 64.
EXAMPLES
% t1asm Utopia-Regular.raw > Utopia-Regular.pfb
% t1asm-a Utopia-Regular.raw > Utopia-Regular.pfa

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. http://part
