I'm trying to write a txt2lrf tool which could convert txt/pdb file of any encoding to lrf.

The txt/pdb file would be rendered using freetype on the local pc and convert to lrf embedded pic object. The render is ready, but I'm having some problems dealing with the lrf format itself.

I've checked http://www.sven.de/librie/Librie/BBeB but the info there is quite unorganized. Does anybody have any other sources on a more thorough document about the format? Or any source code I could refer to? Thanks.

Hmmm.... seems libprs500 could work for me.... guess I should have a more thorough searhing before the post...

Yes, libprs500 sources is the best "reference" there is. And it already has txt2lrf, though not pre-rendered.
