I discovered this is an error in DataURIResolver.
In DataURIResolver the StreamSource created does not the systemid is
never set, thus causing a null value for originalURI which triggers a
NullPointerException.
ImageFactory {
loadImage {
mageReaderFactory.make(source.getSystemId(), in, ua)
}
}
A simple fix in DataURIResolver and rebuilding fop (from the latest
sourc distribution) aalleviates the issue:
source.setSystemId(href);
return source;
I will report this as a bug. Testing this also revealed and error for
PNG files where the transparency layer render black but that is another
issue and coverting to a jpeg fixed that issue.
