Class ImagePool

java.lang.Object
  org.icepdf.core.pobjects.graphics.ImagePool

public class ImagePool
extends java.lang.Object

The Image pool is a Map of the most recently used images. The pools size by default is setup to be 1/4 the heap size. So as the pool grows it will self trim to keep the memory foot print at the specified max. The max pool size can be specified by using the org.icepdf.core.views.imagePoolSize system property. The value is specified in MB.

The pool also contains an executor pool for processing Images. The executor allows the pageInitialization thread to continue while the executor processes the image data on another thread.

Teh pool size can be set with the system property org.icepdf.core.views.imagePoolSize where the default value is 1/4 the heap size. The pool set can be specified in using a int value representing the desired size in MB.

The pool can also be disabled using the boolean system property org.icepdf.core.views.imagePoolEnabled=false. The default state is for the ImagePool to be enabled.
