This sounds like we might have to rethink how we treat the URI when caching the image. If it's a relative URI, we'd have to prepend the base URI and only use the absolute URI in the image cache. I don't think we do that now. That could actually solve your problem. > Anyway, I wonder > how you can generate the SVG on the fly and pass the SVGDOMSource to FOP, as > the image cache is ignoring the URIResolver anyway (as I learned now). The thing is: We assume that a resource can be identified uniquely by its URI. After all there's the word "identifier" in "URI". If the same URI comes back, we assume it's the same image. The URIResolver is only used when we have to load the image (which is done once). The image loader framework then puts the loaded image (subclass of org.apache.xmlgraphics.image.loader.Image) into the cache under this URI, further identified by the ImageFlavor (as multiple representations of the same image can be stored in the image cache). So if you re-request the same URI again, the cache returns the image directly. No detour through the URIResolver. So, to pass in an SVG DOM, your URIResolver will create a DOMSource instead of a StreamSource. PreloaderSVG can make use of a DOMSource, so it doesn't have to be serialized to a stream first, in case you build your SVG as a DOM somewhere. -- Configure bugmail: https://issues.apache.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug.
