Dear Wiki user, You have subscribed to a wiki page or wiki category on "Xmlgraphics-fop Wiki" for change notification.
The following page has been changed by JeremiasMaerki: http://wiki.apache.org/xmlgraphics-fop/ImageSupport The comment on the change is: Added a few words on the current status ------------------------------------------------------------------------------ This page documents aspects around images in Apache FOP. Older design documentation can be found here: http://xmlgraphics.apache.org/fop/design/images.html + + = Current status = + + Some of the content below is slightly out-dated. The "current problems" are mostly "past problems" now, after the [http://xmlgraphics.apache.org/commons/image-loader.html image loader framework in XML Graphics Commons] has been introduced. Performance and memory consumption has been improved as expected. Still, the image handling in the various renderers is still done in different ways. As an example: Barcode4J currently makes calls against the Graphics2DAdapter interface, the ImageAdapter interface, the PSRenderer class and can still use the fallback via SVG. The coupling is too high. The PDFRenderer also still has a slightly different approach at image handling than, say, the PSRenderer. Now, with the intermediate format, all the code that is directly dependent on the Renderer interface becomes a problem for code reuse. = Current problems = @@ -165, +169 @@ = Random thoughts = - It might be good to separate the image dimension object for the layout process from the actual decoded image, thus providing separate caches for both. + It might be good to separate the image dimension object for the layout process from the actual decoded image, thus providing separate caches for both.
