Gscan2pdf reached 1.8.5 release with enhancements


Gscan2pdf, a simple graphical tool to produce PDFs or DjVus from scanned documents, reached the new 1.8.5 release a day ago with some new features.

Five clicks are required to scan several pages and then save all or a selection as a PDF or DjVu file, including metadata if required.

gscan2pdf can control regular or sheet-fed (ADF) scanners with SANE via libimage-sane-perl, scanimage or scanadf, and can scan multiple pages at once. It presents a thumbnail view of scanned pages, and permits simple operations such as cropping, rotating and deleting pages.

OCR can be used to recognise text in the scans, and the output embedded in the PDF or DjVu.

PDF conversion is done by PDF::API2. The resulting document may be saved as a PDF, DjVu, multipage TIFF file, or single page image file.

Changes in gscan2pdf 1.8.5 include:

  • Add support for Poppler (pdftops) as postscript backend.
  • Remove support for libsane-perl
  • Reapply current scan settings for those scanners that reset them when forcing a reload
  • Eliminate unnecessary strings from gscan2pdf.pot to prevent unnecessary work and confusion on the part of the translators.
  • Add A3 to default paper sizes
  • Translation updates.
