JPEG to OCR'd PDF conversion using tesseract v4 through cmd. Includes OCR'ing the JPEG's and combining multi-page PDF to one.
It is just a simple implementation of using tesseract with python (uses os.system for making it work through command line). It works well on windows, however, I couldn't find a way for PDF to PDF conversion using command line as we need to read PDF using command line. On the other hand, reading a JPEG is still possible with libgif 5.1.4 : libjpeg 8d (libjpeg-turbo 1.5.3) : libpng 1.6.34 : libtiff 4.0.9 : zlib 1.2.11 : libwebp 0.6.1 : libopenjp2 2.2.0 libraries present in windows.
I'm currently trying to make ocrmypdf on windows as it shows error in leptonica.py about the dll. It's not impossible to do, if anyone finds a way, you can make changes in the repository in a new branch.
Make sure to install libraries in the same manner
- libjpeg : libpng : libtiff : zlib : libwebp : libopenjp2
- leptonica (v1.78) (you can use any version but you would need to change the location of liblept.so location in the code)
- Tesseract (any version)
- Tesseract Language Data (big tessdata)
- ocrmypdf library
- You need to provide the converted JPEG's of PDF's to the code
- Naming convention for JPEG: PDFname_count (if you want to change, make changes in the ReGex too)
- All the JPEG's must be present in single folder
- OCR folder will be created in root folder
- PDF's will be created page-wise
- Page-wise PDF's will be merged into one parent PDF automatically
- Parent PDF's will be placed in OCR folder.
You can use this repository in anyway you need. Kindly make any changes in a different branch.
