Urgent help needed.

[Purvesh Vora <pu...@patni.com>]

Hi I am trying to print a pdf which has around 20-50 pages.
Each page has one image which is large and is scaled down by fop.
Once the server is restarted it works fine for some time..(can print pdf
containing 5-10 pages )
After that its performance degrages... It takes more and more time to print
the pdf..
I am using fop .2 and enhydra is application server.

Thanks & Regards
Purvesh Vora

The most common way is to use one of the zillions
shareware image processing programs in batch mode.
I personally use still netpbm (seems to have a
follow-on on sourceforge now).

Hi J.Pietschmann,
First of all thanks for the response.
Please tell me if there is any way to scale down the graphic using java if
you know.
Thanks & regards,

FOP caches the images, and they usually take a lot of memory.
It could help to scale down the images before they are fed to
FOP. In some cases, as for JPEGs, other methods to reduce the
image file size work too, like using a higher compression.
