It should work the same as if you draw the image into a TBitmap: if it's drawn with transparency, the litePDF should pass it to the PDF with transparency as well. I'm pretty sure that your code snippet does not honor the transparency, because there are TPicture/TBitmap properties for it (set the transparent color & a bool that the color should be used for the transparency; something like that). I'm also not sure whether the PNG transparency had been preserved on the image load. I guess the TPicture lost the PNG data as soon as it loaded the file, but I'm not sure about that. Otherwise you are right, if everything fails, you can use the PoDoFo functions to achieve it. By the way, the PoDoFo list has nothing to do with the litePDF project.
