Hi, Thanks for replying so quickly. I'm not an expert on this, but I know that pdflatex now support including JBIG2 files in PDFs. There is a writeup at http://www.circuitwizard.de/pdftex/jbig2/jbig2.html According to that page "Adobe Systems have defined a new filter /JBIG2Decode in their newest PDF format, version 1.4, which allows decoding of image data after the JBIG2 standard. It seems that this feature is first supported by Adobe Acroread version 5.0." It seems to be documented in: http://www.adobe.com/devnet/pdf/pdfs/PDF14Deltas.pdf Best wishes and many thanks, Chris. _______________________________________________ Magick-developers mailing list Magick-developers@imagemagick.org http://studio.imagemagick.org/mailman/listinfo/magick-developers
