Unfortunately the fonts were substituted (I haven't originals), but editing the substitution list is possible. I changed the text color from transparent to black, deleted the JPG and I had 20 pages with readable and editable texts. It shouldn't have OCR, so the text is included. I tried Affinity Publisher (for first 10 spreads only). Adobe Reader either reads and recognizes the text images or OCR result is included in PDF as "OCR-layer". You probably have noticed that the text is selectable in the PDF. I guess people with programming skills could write something better. A not so clever idea is to place them to an otherwise empty layout and print a PDF. You need a way to combine the edited JPGs back to a PDF. This is a sample screenshot from Paint.NET: Unfortunately you do not use Photoshop where the script can be a recorded action which needs no programming skills.įast manual adjustment is possible in Paint.NET which remembers the last edit and offers the same settings automatically- simply open say ten spreads and apply the same levels adjustment to all. It produced into one folder the spreads as separate JPGs and numerous 1x1 px PNGs which seemed to have no actual function, so they can be deleted.Īny scriptable photo editor would shift the levels in the same way in all files. You can extract image files from the PDF with some PDF exploding program. I haven't modern Acrobat Pro, so this cannot be considered full answer. The resulting PDF file was about 8.6 MB (using 300 dpi for the output from ScanTailor). Here's a sample of the output with 2 pages per page: Re-processing a PDF like the one you shared just takes a couple of minutes (it took me longer to write this response, actually), and the results are like the following: (They also use R, since it's what I'm most comfortable with, but you can easily convert it to bash.) The only step that requires manual review is the ScanTailor step, but ScanTailor itself is pretty fast. I use Ubuntu, and I've created scripts for steps 1, 3, and 4.
