Re: Problem with SVG

[Johannes Franz]

By the way i just read that there is a function to clear the image cache. Do 
you think that there is a good position in the jars to set this function. I 
would like to reset the cache after every image, because for my uses i don't 
need a cache. Most of the embeded images are unique and it doesn't depend on 
the time to create the pdf but on the amount of images i can embed.

Yes,
i just wanted to test first how to embed one graphic. then i wanted to 
copy the file - lets say - 100 times and rename it. then i wanted to run 
my test...

Hi,
FYI: since your original question also mentioned 'how many svgs can one
embed before the OOMError occurs?', here's a little advice.
You won't be able to accurately test this with just one SVG, you'd need 
to
have quite a few and all different, because if it's the same one, FOP 
keeps
it in a cache anyway. I haven't exactly tried myself, but I'm guessing 
that
if you embed the same graphic once or 100 times, it shouldn't make that 
much
of a difference...

Besides that:
But when i run fop i get the following error message:
[ERROR] Batik not in class path
[ERROR] Error while creating area : No ImageReader for this type of 
image
(file:/home/johannes/AT_PI.vdo/diagram.svg)

What's the problem?
...
batik.jar seems to be added.
From my fop.sh:
DIRLIBS=${FOP_HOME}/lib/*.jar
And batik.jar is located in /lib. So any other idea why this problem
occurs?
Hmm... I get the very same error you describe here when I try to render 
your
supplied files.
Very strange indeed... Only place this error message appears in FOP is in
fop.image.analyser.SVGReader, as a result of a NoClassDefFoundError while
trying to load the image using Batik's classes...

I'm having no trouble viewing the SVG with Batik Squiggle, but I do
encounter problems trying to rasterize it, albeit not a NCDFError
Is it possible that Batik *is* loaded, but the rasterizer can't handle 
the
SVG for some reason, so one of its classes is actually causing the error?
Forcing FOP to deal with it, but that's not exactly what the message in 
that
'catch' block was meant for...
In any case, you might want to check on batik-user, and ask if someone 
over
there has a clue why this 'diagram.svg' won't work with their rasterizer.

Greetz,
Andreas
