Hi Thierry,
Thanks your advice. I tried dynamic renderer also. It has not
improved the memory usage much. More over peroformance is too worst. I am
sending the code which converts svg file to buffered image for desired size.
Please have a look at and suggest me to improve performance and memory.
Thanks in advance
Bala
