Hello all,
I just ran into rather strange problems during FO processing, causing the
exception shown below. My research (web searching, FAQ & mail archive etc.)
turned up blank.

What I did and what happened:
Two png images are to be included into a pdf. Exceptions occur, finally
resulting in a null image. PDF is generated, can be viewed, but one image is
missing. There's just empty space of correct dimensions in the document.
Circumstances:
Both images are fetched from a web server. Both are available by URL in a
browser and both can be opened by an image editor program, meaning the files
themselves seem to be ok. Loading the images from remote by a small java awt
test application (using ImageIO) works fine. Both images were created by
conversion to png (ImageMagick), one using a wmf as source the other having an
emf as source. Both images share the same filename but are from different
paths/URLs.
Java 1.6.0_06
fop.jar: Implementation-Version: 0.94 (OxygenXML 9.0.0 eclipse plugin)
fop.jar: Implementation-Version: 0.20.4 works just fine (XMLmind FO converter
3.1 without VM))
What happened? Any ideas? Upon request I'll gladly provide both images, the
minimal fo source, and the pdf result.
Best regards and thanks in advance,
Michael Glass
