[Podofo-users] Example of text removal or image extraction

[Jacob P. <Jac...@fo...>]

Hi

I have a multipage PDF containing text and images.

I need to either;


  1.  Remove all text from PDF so only images remain.
  2.  Create a new PDF where I copy over images from source.

Basically the result should be the same – a PDF with only the images of the original.

Next I need to extract all the pages of PDF to a multipage TIFF where I specify the DPI. If text removal is possible (1), I can probably skip a step and go straight from in mem PDF without text directly to TIFF output?

I will run OCR on TIFF file and this will give me some text that I need to add to original PDF using transparent ink.

I have googled around but need a few pointers regarding PoDoFo – not the OCR bit 😊

Thanks
