Question: How to change PDF text colours and remove background, with PDFBOX or other
Hi, I want to make an apllication using pdfbox that changes all the text colour to black and removes backgrounds so pdfs can be printed saving ink.
Unfortunatelly I haven´t found any good place to read how to use pdfbox, I've found the api but that doesn't seem to be very descriptive and the examples only helped me to find out how to browse all the pages of a pdf and with any luck save changes.
Can anybody help me out?
I'd like to know how to change colour for all the text and how to remove backgrounds (I think they are called background paths) and maybe background images.
