![]() ![]() Fix: Adding a patch file for configure: How-To-Repeat: Install graphics/djvulibre and run 'firefox about:plugins'. If DjVu document has color images, then they'll be usually placed on background layer in this case user can take advantage of tools like ddjvu (extract only background layer) and imagemagick (auto-crop) to output just images instead whole canvas, but it can't be automated for creating PDF outputĪnother saner, but slower approach is use of regular OCR GUI tools. Browser plugin included in graphics/djvulibre does not working because appropriate X11 libraries are not linked to nsdejavu.so plugin module. Lengthy comments below discuss representing smaller images from DjVu document page as separate objects, which is not easily possible because DjVu document page is itself just a single image with optional text layer, with no "information" about smaller images as separate objects. Which is identical to input DjVu file and has text layer inside: Then this nifty program takes care of everything that's inside this folder (HTML and TIFF files with same base name) and produces output PDF file with some by-products: sample.djvu This is where pdfbeads comes in play, and we simple execute: files in Adobe Systems' PDF (Portable Document Format) format. So that we end with these file in out work folder: sample.djvu Usually you do this because either Firefox doesn't include the feature you want or you. Now we extract DjVu page to TIFF format with:ĭdjvu -format=tiff -page=10 sample.djvu pg10.tif Sed intervention corrects class names in output hOCR (which is just simple HTML file) We can use djvu2hocr command (from ocrodjvu package) to extract hidden text layer from DjVu file (it doesn't do any OCR or similar, it just extracts text layer with geometry), i.e.:ĭjvu2hocr -p 10 sample.djvu | sed 's/ocrx/ocr/g' > pg10.html pdfbeads, that has it's own requirements which can be found by Google. ![]() An incomplete uninstallation of a program may cause problems, which is why thorough removal of programs is recommended.Here is one way, which would require some not so common tools: There could be other causes why users may not be able to uninstall DjVuLibre DjView. Another process is preventing the program from being uninstalled.Due to an error, not all of the files were successfully uninstalled.A file required for the uninstallation to complete could not be run.Many viewers use the same library, making a vulnerability in a single library relevant to large number of viewers. The program’s built-in uninstaller does not start or does not operate properly. While, as others have mentioned, it is designed not to have any executable code, a vulnerability in a DjVu parser can be used to exploit the viewer. ![]() Possible problems that can arise during uninstallation of DjVuLibre DjView If youre not sure which to choose, learn more about installing packages.
