  • Write multi-page scan to PDF, DjVu or TIFF
  • Write single scans to any format supported by ImageMagick
  • Ocropus & tesseract support
  • Place OCR output at boundary boxes supplied by Ocropus
  • Incorporate PDF metadata in filename

Changes in the latest Gscan2pdf 1.8.4 include:

  • Cope with Tesseract 3.0.5 writing Page 1 instead of Page 0
  • Assume pixels/inch if the image doesn’t know better.
  • Fix paragraph formatting in save as text output.
  • In preparation for future removal of libsane-perl frontend, change default frontend libsane-perl -> libimage-sane-perl, and similarly switch selected frontend on upgrade from older version. Assuming no major problems occur, support for libsane-perl will be removed in the next release.
  • Fixed bug writing postscript file.
