And cpdf can in some cases do that well, however I had no sucess with using:-Ĭpdf -blacktext -color black -opacity 1.0 in.pdf -o out.pdf When you strip the image then nothing showsĪt this juncture you have a few choices, but generally you need to blacken what's left. Several things to note, the colorless text is often not aligned with the real letter positions since character word blocks or lines need to be averaged out, so there is a tendency for lower in most cases even to the point (pun :-) in worst lower cases (pun :-) it looks just as high as under lines (yet another:-) width is often set to 1 point, no stroke, no fill. The answer is very very dependent on how the OCR was done, here is an exceptionally perfect result sample from AWS-textract (reality is im(g)perfect as it depends on each image)
