Is there a way to merge different layers of the PDF into one single layer? I have a CAD-file where I need to hide a company logo. So I put a rectangle above it, then I print everything to a PDF. When I open it again the company logo is visible for a millisecond because it draws the background first and when it´s ready the rectangle is drawn. Is there a way to merge everything into ONE SINGLE background image inside the PDF?
Isn't it better to use the Blacken PDF tool here? There the modified page is rendered to an image and the image is replaced with the original page contents. This way, no one can read/see the content below.
