Unfortunately this can't be changed easily in the 0.20.x branch. It would be nice if the next version of fop could provide a means to either turn off image caching (as a configuration option) or to limit the cache size. The redesigned code apparently discards pixel information after it is written to the result stream, and it also supports reuse of PDF objects better, so this may be actually implemented. Note that limiting the cache size can lead to unexpected behaviour for dynamically generated images.

Re: OutOfMemoryException
I thin i will try it nevertheless, because i don't know what to do otherwise. I really need to create a pdf which contains a lot of images. Do you have any other solutions for my problem? - Original Message - From: J.Pietschmann [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, August 11, 2004 9:18 PM Subject: Re: OutOfMemoryException Bernd Brandstetter wrote: I had a similar problem some time ago when I tried to create a PDF containing hundreds of SVG images.

Do you have any other solutions for my problem? Try JPEG. It shouldn't require as much ressources as PNG. Bump up physical memory of the machine, 1G or 1.5G, and allocate as much as possible for the JVM. Disable swapping. Using JPEG and wrap it in an SVG might help too.

Re: OutOfMemoryException
The problem with JPEG is, that it really supersizes my pdf. But i'll try it.

The used java library is jimi-1.0.jar. If i include to much png-images i get the OutOfMemoryException. The answer of the FAQ is to increase the memory which is allocated for java. Could you explain me how i can do this? Do you have any other solutions for the OutOfMemoryException? Do you thinks using JAI instead of JIMI could help? Greetings, Johannes.

Do you thinks using JAI instead of JIMI could help? It depends. It is likely the problem is caused by the image cache. Reducing the PNG resolution or switching to a format which compresses better (low quality JPEG) might help.

Re: OutOfMemoryException
I forgot to mention that I am using a batch process which only uses the function one after another and not parallel. Perhaps the solution to my problem is to reduce the maximum Number of parallel Threads to 1. It seems that the programmers of fop set this number on 5. Perhaps somebody knows the position in the jar where i can reduce this number. (I am using Jai for the png) Greetings, Johannes. - Original Message - From: J.Pietschmann [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Tuesday, August 10, 2004 10:00 PM Subject: Re: OutOfMemoryException Johannes Franz wrote: i am buildung a pdf which includes png.
