Yes. > Has anyone done it? I dont' know. > The FOP-related question is: Even if this is possible from an XSL-FO > standpoint, is it possible using FOP 0.20.5? Yes. Create a FOP extension as described here: http://xml.apache.org/fop/dev/extensions.html As an example for a FOP extension you can have a look at my pet project, Krysalis Barcode (in the process of being renamed to Barcode4J), at http://barcode4j.krysalis.org. The relevant sources are here: http://cvs.sourceforge.net/viewcvs.py/barcode4j/barcode4j/src/fop-0.20.5/java/org/krysalis/barcode4j/fop0205/ I think this extension should give you some idea on how to create an extension that can load a bitmap embedded in a fo:instream-foreign-object. Not everything's there, you might need to modify the FOP sources a bit, but it's definately a possibility. > Deadlines are looming. Answers would be greatly appreciated. Thanks in > advance. Ok, you've got a deadline, so I would suggest you take the easier route to create a servlet that reads the bitmap from your database. In this case you only embed a URL in a fo:external-graphic to references the image you want to appear. I hope this helps. If you decide to create that extension for the in-stream bitmaps it would be cool if you could share it as I remember that this is a topic that has come up before. Good luck.
