Package: gscan2pdf Version: 2.11.0-1 When opening pdf files with multiple images per page or no images, gscan2pdf loads the pages as multiple mangle fragments or gives an error that the file cannot be opened because it contains more than one image per page. This occurs with both a drag & drop to the left panel and also the open file from the menu.
This is generally understandable because as a scanning software, there should only be one image per page. However, pdf scans from other software do not always follow this, nor do most other pdf files. Although I really prefer using gscan2pdf, I am often stuck using other software to make them compatible with gscan2pdf. Okular > Print to File > Force rasterization GIMP > import > export as pdf Since both of these alternatives are open source, hopefully this functionality could be eventually included in gscan2pdf. To reproduce: 1) Download a pdf file from Wikipedia https://en.wikipedia.org/api/rest_v1/page/pdf/Main_Page 2) Open with (or drag & drop to) gscan2pdf 3) File opens as a bunch of mangled fragments. The it gives this error: Open File Error "Warning: gscan2pdf expects one image per page, but this was not satisfied. It is probable that the PDF has not been correctly imported. If you wish to add scans to an existing PDF, use the prepend/append to PDF options in the Save dialogue." 4) Open the file pdf file with GIMP, export as pdf, check "Layers as pages...", uncheck "Convert bitmaps to vector...". 5) Open new file with gscan2pdf, works perfectly 6) Open the original file pdf file with Okular, print to file, Force rasterization 7) Open new file with gscan2pdf, works perfectly Version info: apt search gscan2pdf gscan2pdf/stable,now 2.11.0-1 all [installed] apt search gimp gimp/stable,now 2.10.22-4 amd64 [installed] apt search okular okular/stable,now 4:20.12.3-2 amd64 [installed] uname -vr 5.10.0-9-amd64 #1 SMP Debian 5.10.70-1 (2021-09-30)
