There's a JBIG2 encoder here: https://github.com/agl/jbig2enc Since it uses Leptonica for some of its internal operations, adding it to Leptonica might be a little cyclical (or require some restructuring). While Jeff obviously has more experience than I, it seems like it should be a straightforward integration. Non-trivial to be sure, but certainly doable. The PDF output module already supports multiple encodings, including the 1-bit G4, so it *seems* like it should mainly be a matter of filtering/transforming the segments in the JBIG2 stream and creating stream for the global symbols, if needed. Jeff - are there particular troublespots that you foresee if someone were to tackle this? Tom -- You received this message because you are subscribed to the Google Groups "tesseract-ocr" group.
