Keep the outline in source PDF files
I had carefully merged 35 separate scanned chapters of a doc in PDF so as to have an outline (using PDF Lab).. and when I OCR'd it in VelOCRapter (keep the name!) I lost the outline. I know, the quick solution is to OCR them <i>before</i> I merge them, but it would be nice not to have to do them one by one.
Thanks for this feedback, to be honest I hadn’t even considered this, so it’s good to know when there are issues.
We currently extract images from the source PDF, feed it through the OCR, and then reassemble a new PDF blind. This leads to the sort of problems that you are having. It would be quite a major architectural change to support updating an existing file, but I can see advantages, and will look into how it might be achieved.
