Hello, I would need to remove (often low quality) invisible text placed on images by tools which use OCR to make searchable PDF.
We use pdfbox ourselves to make searchable PDF... and we use setRenderingMode(RenderingMode.NEITHER); when we place the text to make it invisible.We also use pdfbox's text stripper to remove text from PDF. What I am not sure if there is a way for the text stripper to identify the characters that have been placed as invisible and only remove those in some cases. Thanks for your help, Luca
