GScan2PDF, graphical to produce PDFs or DjVus from scanned documents, released version 2.8.1 a day ago.
The previous program launching issue should be fixed in the release, though it didn’t happen in my machine. Gscan2pdf 2.8.1 release highlights:
- Pass resolution to tesseract to avoid messages like “Warning! Invalid resolution 0 dpi. Using 70 instead”
- Cope better if data model becomes corrupted
- Add restart option to ‘device not found’ mini-wizard & if tmp directory changed.
- When saving a session file, note that pages have been saved to avoid ‘Some pages have not been saved. Do you really want to quit?’ message.
- Improvements to the Crashed sessions dialog to make it more intuitive.
- Update position of OCR text when cropping
- Create PS level 3 instead of 1.
- Fix check for unpaper version. (Scan fails if unpaper is not installed but selected in post processing)
- Fix check for tesseract version. Remove support for tesseract < 3.04.00.
- Update translations.
