Tilman Hausherr commented on PDFBOX-1435:
-----------------------------------------
I get the effect "text is obscured by the Images,and Images is showed in
reversed color" if I extract the embedded images first, with code like in
processResources() in ExtractImages.java. The effect is related to PNG images
only (PDPixelMap), and goes away if the PNG image isn't cached, by not
assigning the variable "image" at the end of PDPixelMap.getRGBImage(). Thus
there must be a difference in the image depending whether it is built before or
within RenderUtil.convertToImage(). I haven't researched what the difference is.
