Hi everyone, i need your help...i made a PDF document by scanner a paper document and merged it with the result of an OCR operation. Now i see the correct layout of the document but when i copy and paste from it i see many errors (OCR errors). I want to know if i can modify the text under the image with quickpdf library (for now i retrieve the text content only). thanks

Hi there, Currently it's not possible to edit text in a PDF using Quick PDF. You can extract text and you can add text, but you can't edit text directly in the PDF. For this you can try something like Nitro PDF (www.nitropdf.com) or Acrobat. But editing normal text in a PDF is usually difficult, so editing text which has been OCR'd could be problematic indeed. Goodluck! Cheers, - Rowan.

| yes but perhaps i can read text and image from the source, filter the text in some manner, and write the result on a new file? Isn'it? |

Yes, if you want to extract all text and images and then write that to a new PDF, then this is possible. Sorry, I didn't think that would be an acceptable solution to you. But it would definitely work. Here's some sample Delphi code that has been used to do a similar job before: http://quickpdf.org/forum/extract-text-and-images-and-insert-into-new-pdf_topic1308.html - http://quickpdf.org/forum/extract-text-and-images-and-insert-into-new-pdf_topic1308.html

Only because usually when someone wants to edit text in a PDF re-writing out the entire PDF by extracting the text and images isn't an optimal solution. It's much quicker and more efficient to directly edit the text in the PDF -- but Quick PDF Library doesn't support that direct editing of text. However, in hindsight, re-writing the PDF -- given that it's an OCR'd PDF -- is actually probably the best thing to do.
