Transparent PNG DrawImage

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   If I call AddImageFromFile, with options = 0/normal, and then later call DrawImage, if the image loaded is a PNG with an alpha layer (for transparency), will QPDF merge the image using the alpha layer? This isn't quite the effect I'm getting, so I wanted to be sure that this was supported functionality. Is there something I need to do to "enable" this (I've tried a few different options in AddImageFromFile, with no visible effect)?
