Embedded images with data-url

[Pascal Jungblut <pa...@med.uni-muenchen.de>]

Hello Guys,

I'm currently embedding FOP 0.95 into my application (using a Java bridge). 
For testing, I took the example Java-snippet from the documentation on 
apache.org which processes the FO like it should.
But there is an issue with images: when I use the FOP-commandline-tool 
base64-encoded images (data-url) are included (gif/png) in the outfile. When 
I use my simple Java class, there is no image in the resulting PDF. Instead, 
the the parts of the PDF are simply white.

May I have to add one more processing-step?

Regards,
Pascal

Hmm, no such problem on my side.

Data URLs (RFC 2397) are decoded by FOP's
org.apache.fop.util.DataURIResolver which is called by
org.apache.fop.apps.FOURIResolver. If I had to guess, I'd say that you
either get an error message somewhere in the log because the data URL
was somehow wrong or you're using a custom URIResolver which doesn't
behave correctly. But for the latter case there's actually code in
FOUserAgent, that should bypass the custom resolver in the case of data
URLs.

Try setting a breakpoint in FOUserAgent.resolve() to find out what's
going wrong.
