Greetings,
I am using the laest version of the PC PDF24 toolbox. I see there is a "Flatten" tool but i reality it only flattens comment/text boxes I guess.
I think it will be quite useful under the FLATTEN TOOL to have two options. One for the current behaviour and a second FLATTEN ALL which turns a layered PDF (txt, images, everything) into a PDF made out of a static image. Not able to copy and edit. Also there could be an option for the DPI of the image insie the PDF.
I believe this is a good security feature in certain cases.
