I thonk there's a little more involved in importing a font from the Mac to the GS. According to the Toolbox Refernce 2 each of the GS fonts has a header that looks something like this: offsetToMF - integer: number of words to mac font part family - integer: font family number style - integer: style font was designed with size - integer: font point size version - integer: version number of font fbrExtent - integer: font bounds rectangle extent highhowTLoc - word: high order word of address to offset/width table ............ - bytes: extra fields, if any The last of the named fields is from the Toolbox Reference 3. The next part, as far as I can tell, is the Macintosh font record. Its format is: fontType - word: font type. Ignored on the GS firstChar - WORD: ascii code of the first character defined lastChar - WORD: ascii code of the last character defined widMax - WORD: maximum character width kernMax - WORD: maximum leftward kern nDescent - WORD: negative of descent fRectWidth - WORD: width of font rectangle fRectHeight - WORD: height of font rectangle owTLoc - WORD: low word of pointer to offset/width table ascent - WORD: font ascent descent - WORD: font descent leading - WORD: leading rowWords - WORD: width of font strike in words bitimage - array (1..rowWords,1..fRectHeight) of words called the font strike loctable - array (firstChar..lastChar+2) of integer locationth table owTable - array (firstChar..lastChar+2) of integers offset/width table Hope this info helps. Shouldn't be too hard to throw together a little program to shove a header onto a Mac font. Just be careful that you ascent - WORD: font ascent descent - WORD: font descent leading - WORD: leading rowWords - WORD: width of font strike in words bitimage - array (1..rowWords,1..fRectHeight) of words called the font strike loctable - array (firstChar..lastChar+2) of integer locationth table owTable - array (firstChar..lastChar+2) of integers offset/width table Hope this info helps.

Shouldn't be too hard to throw together a little program to shove a header onto a Mac font. Just be careful that you don't use an existing font number. Also, the version field in the GS font header should be set to the current (IE: system 5.04) QuickDrawII version number, to ensure that QuickDraw recognises the extra field. +----------------------------+--------------------------------------------+ | Corey Murtagh | "Ye who doubt, believe, for the Apple | | electric.monk@kcbbs.gen.nz | II lives on!" - ME | +----------------------------+--------------------------------------------+ don't use an existing font number.
