Memory and Large Images

When generating very large images, it is necessary to increase the heap size to allow for greater memory usage if the following message appears:

"The image is too large, please increase the Java heap size."

It is possible to increase the Java heap size by modifying these runtime parameters:

java -Xms<initial heap size> -Xmx<maximum heap size>

Default values:

java -Xms32m -Xmx128m

For example:

java -Xms128m -Xmx256m or java -Xms128m -Xmx512m
