Peter,
the parser is like a platypus - it doing not much - just parse CFF font and create some CFF-specific objects. As I already said, this is only half of work - I have to implement Type1 font writer to make that work. Regarding hack, I think that PdfBox already has it. You may get encoding and font metrics from it. What I really don't understand is - what is exactly does not working? If Font is working on "normal" Graphics it should also work on your "hacked" graphics. So what is your problem???

It uses FontFile3 stream. FontFile3 stream contains font either in Compact Font Format ( CFF) or OpenType Format (OTF) which are not supported by java. The font name is "FKAJPF+AdvOT3b30f6db.B" which means that it is subset font of font named "AdvOT3b30f6db.B". I am ignorant about fonts so please correct any errors. I don't know exactly how PdfBox handles CFF/OpenType fonts, probably they just search for surrogate font (by name) or some kind default font (since I never saw such horrible font name in system fonts). I have no idea where the font came from. It's probably created by the publisher or bought from a supplier. I don't know if this is really useful for you. It's very useful! First it explains why I had problems and gives me confidence in the process. I also have no idea why font name/style are not set. It may be nevertheless valid font. BTW The only way to make java understand CFF/OTF fonts is to convert them to Type1 fonts. I doubt that there are any free java program which could do it. Thanks for the information. / (I managed to write parser for CFF fonts, but still have to dig into Type1 font format, however my to do list is really long and Type1 format in not on first place ;-)) What does the parser do? Best Regards I shall probably create a hack of some kind. I can find a san-serif and serif which are "fairly close" and substitute them. How would I get a system COSDictionary I could substitute? I am mainly interested in: * the identity of the characters * the font metrics of the characters. In this way I can guess the words and the spaces between them.
