                I've linked up a the whole lot of jira's that fall under transparency group support there are problably a few more but this is a good start especially given the folder of other samples we have in QA. The menu's on page that don't correctly are actually quite complex and will take some time to implement a solutions that will correct the rendering.

                Unfortunately we have to move this out to 5.1 with intent of implementing transparency group support.

                The xObject smask value is now respected and the show on the play button is now properly show. The only problem that remains is to figure out why the background isn't being painted for this button. To enable the smaking set the system property org.icepdf.core.disableXObjectSMask=false.

                A lot of work has gone into improving our support for transparency groups particularly around various blending modes. As result this PDF is now correctly rendering using a multiply blend mode.

                Further work is needed to generate the embossed effect but a new JIRA will be created for this as we have a few samples now.
