We can't paste a .png image from one PDF document to another one correctly at all. We have these seals that we want to paste in the same place on several pages of a PDF, and usually when we do this the pasted image has a different size, is in a different location on the page, and worst the transparent background of the image gets turn to black basically. This used to work fine in Adobe Acrobat Pro X. How can this work in Adobe Acrobat Pro DC?
