Request, that Chocolatey installation will be possible.
How to tesseract multiple files in the same folder from command prompt?.How to run Tesseract with multiple languages one time?.Windows installation request, that Chocolatey installation will be possible.See my bugreport for details: bug(pdftoppm): -: Error writing TIFF header. Converting to TIF doesn't worked for me convert your PDF to JPG.You will need to download fonts from Internet or use fallback fonts.
If your PC haven't required fonts, pdftoppm show it.Pay attention to -r and -jpegopt, that set quality of outputed images. pdftoppm of XpdfReader is another utility with fewer options please, do not confuse Poppler and XpdfReader versions.Install Poppler for Windows (I add request, that Chocolatey installation will possible) - pdftoppm is Poppler part.I don't know, how question author was going to use the CLI programs and I don't saw his examples maybe in his cases it would be nice use another commands.įor details about this script, please, read section below “Commands description”.For simplyfying I don't added additional options or commands for better quality and compression, but it would be nice do add it.Sejda-console merge -f *.pdf -o KiraSuperheroFinal.pdf Use this script for it: pdftoppm -jpeg KiraSuperhero.pdf KiraSuperheroįor %i in (*.jpg) do tesseract %i KiraOutput/%i -l rus+eng pdf You can convert your PDF to images → Tesseract will add OCR for your images and will convert images to PDF. You can use some PDFXEdit commands, but for OCR actions GUI required.ĭownload this program (Chocolatey installation supported) → download pack for your language(s) if needed → add OCR to your PDF settings in my case: Unfortunately, you can't add OCR layer, use command-line interface. I hope, that all bugs, that described in my answer, will be fixed.įor example, I selected KiraSuperhero.pdf - bilingual (Russian and English) PDF file without OCR it contain first 14 pages of real book (I don't added in example full book, because testing operations for it may take a long time). In the future data of this answer may be obsolete. This answer is relevant for 19 August, 2019. See “Problems” section, to find out what disadvantages of these alternatives do I consider significant. In section “Suggestion” I suggest alternatives. Possibly, for August, 2019 there are no programs suitable for all requirements.
