I've used the Extract Images Command Line Tool to get the images. Erik

What I did is to look at the rendering and it looks like in Adobe Reader. I also looked at the images with PDFDebugger, that one shows the images with the mask applied. The second image is at Root/Pages/Kids/[0]/Resources/XObject/Im002 and it shows colored text. The image is DCT encoded. The mask is black and white text that is jbig2 encoded. http://imgur.com/a/2ofjD What do you get? Is the jbig2 decoder in your class path? For PDFDebugger, you need to do this: java -Dsun.java2d.cmm=sun.java2d.cmm.kcms.KcmsServiceProvider -cp "pdfbox-app-XXXX.jar;lib/*" org.apache.pdfbox.tools.PDFBox PDFReader filename the subdir "lib" has the additional jars.
