I'm using FOP 0.95, and have happily been running with a custom URIResolver
class to load and embed SVG images into my PDF output.
Earlier today I changed the build process so that all the jar files that were
required by FOP to be in the classpath were un-jar'd and included in my main
.jar file. Since then, I've not been able to load a single image. Here is my
resolver class:
private class ImgURIResolver implements URIResolver {
private static final String uriprefix = "img:";
private URIResolver defaultResolver;
protected ImgURIResolver() {}
public ImgURIResolver(URIResolver defaultResolver) {
this.defaultResolver = defaultResolver;
}
public Source resolve(String href, String base) throws
TransformerException {
if (href.startsWith(PREFIX)){
String name = href.substring(uriprefix.length());
try {
for( int i = 0; i < PDFRenderer.images.size(); i++ ) {
Image img = PDFRenderer.images.get(i);
if( img.filename.equals(name) ) {
return new StreamSource(new
ByteArrayInputStream(img.filedata));
}
}
} catch (Exception e) {
throw new TransformerException(e.getMessage());
}
}
return defaultResolver.resolve(href, base);
}
}
The images are loaded into memory in another class, and I can confirm that the
img.filedata is there.
The errors I see are as follows:
242405 [pool-1-thread-2] ERROR org.apache.fop.fo.FONode - Image not available:
No ImagePreloader found for img:myimage.svg
242408 [pool-1-thread-2] ERROR org.apache.fop.render - Image not found:
img:myimage.svg
Inline SVGs work as expected.
I'm at a loss as to what has changed... I've not removed any files, or changed
anything other than the build.xml file to unjar dependencies & bundle
everything into one file.
Any ideas on how I can investigate/resolve this?
