I seen in jbig2enc.cc
http://github.com/agl/jbig2enc/blob/c70 ... big2enc.cc

was included patch (before it was included in main trunk, I patched myself taking fix dpi patch), giving ability to jbig2enc to code rightly DPI, so it it a problem of program /way to produce pdfs by resulting jbig2 files
it is a matter worth of investigating
meanwhile, knowing physical size of book scanned, you can apply this workaround
with Impose tool inside multivalent

Code: Select all
java -cp /path...to/multivalent.jar tool.pdf.Impose -dim 1x1 -paper widthxheightin file.pdf
Code: Select all
java -cp /path...to/multivalent.jar tool.pdf.Impose -dim 1x1 -paper 8.5x11in file.pdf
in my experience, OCR ability is not influenced by this little problem, since even DPI is not settled, what it is important for good OCR is a CLEAR, BIG (in size) image
