targetrenderer set to MIME_PNG fails in fop >=1.0 but succeeds in 0.95

2012-12-22 Thread Milo van der Zee

Hello dear apocalypse survivors,

I'm using FOP for a couple of years now and thought it was time to
upgrade to version 1.1. Problem is that the rendering to PNG stopped
functioning. It all still works with version 0.95.

PDF generation is still fine. The difference between PNG and PDF
generation is the mime type of fop generated with the factory.
Strange thing is that the call to 'userAgent.getRendererOverride()'
returns 'null' in version 1.1 and returned the expected PNGRenderer in
version 0.95. Is this a bug or is something changed between versions in
relation to PNG rendering?
>From the debug info I see that the renderer does create a page. It seems
like the link between the rendererImpl and the mime-type is not found.
But where can I force that?

See code fragments below.

Thank you very much for any help.,
Milo van der Zee

Can you start with the embedding.ExampleFO2PDF.java example (in 
examples/embedding/java), change the mime type to MIME_PNG (and rename 
all the PDFs to PNGs) and confirm that the new example does generate a 
PNG file? I just tested that with trunk and it worked.

From the debug info I see that the renderer does create a page. It 
seems like the link between the rendererImpl and the mime-type is not 
found. But where can I force that?
