NAME
       t1asm - assemble PostScript 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 speci-
       fied 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 unimpor-
       tant 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 consisting wholly of hexadecimal digits.) The default is 64.

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

       Adobe Type 1 Font Format is available  free  from  Adobe  as  a	PDF  file.   http://part-

       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 Jen-
       son and Kepler.	http://partners.adobe.com/asn/developer/PDFS/TN/5177.Type2.pdf
