Well, it depends on what is desired. If you create a monochrome image then obviously a binary type is preferred to minimize memory usage. We might also want to distinguish grayscale and full color bitmaps (24bit RGB). So we need a way to configure what kind of image is generated and how it is serialized. <snip/> > > One more thing: Why did you include the codecs in the patch?

Download Batik from CVS as you do for FOP and set up the project in Eclipse and reference it in your FOP project (second tab "Projects" in "Java Build Path") instead of adding batik.jar to the project. <snip/> Jeremias Maerki
