The t1utils tools allow you to convert between PFA (ASCII) and PFB (binary) formats; disassemble PFA or PFB files into human-readable form; and reassemble the human-readable files into PFA or PFB format files. You can also extract font resources from a Macintosh font file (ATM/Laserwriter), or create a Macintosh Type 1 font file from a PFA or PFB font.

There are currently six programs:

t1ascii Converts PFB files to PFA format.

t1binary Converts PFA files to PFB format.

t1disasm Disassembles a Type 1 font (PFA or PFB format) into a raw, human-readable text form for subsequent hand editing, tweaking, hint fixing, etcetera...

t1asm Assembles a Type 1 font into PFA or PFB format from the human-readable form produced by t1disasm.

t1unmac Extracts POST resources from a Macintosh Type 1 font file (ATM/Laserwriter) into PFA or PFB format for use outside the Macintosh environment. The Macintosh file should be stored in MacBinary, AppleSingle, AppleDouble, or BinHex format, or as a raw resource fork. Note that t1unmac does not have to run on a Macintosh, but makes Macintosh Type 1 fonts available for use on Unix machines and PCs.

t1mac Creates a Macintosh Type 1 file from a PFA- or PFB-format Type 1 font. Writes the Macintosh file in MacBinary, AppleSingle, AppleDouble, or BinHex format, or as a raw resource fork. WARNING: This tool will not suffice to allow you to use the new font on a Macintosh, as Macintoshes cannot read raw Type 1 fonts. You will need to create a font suitcase containing bitmap fonts. If you do not already have such a suitcase for the font, T1utils will not help you create one.
