Hi,I would like to be able to open a PDF, remove any printing limitation, and re-save. Other than that limitation, nothing should change. I am using PDFFileSecurity to change change the priviledge, and save it to stream, which is then written to file. However, there seems to be a loss in fidelity with the original file. I've attached a zip file containing two PDFs (one original, one saved), and an image depicting the issue. It should be easy to see...in the original, there is some bolded text at the top, while it is no longer bolded in the saved file. Does this you are parsing the whole file and recreating the file, as opposed to just modifying the property? Do you know of similar fidelity issues?
