Avoid OutOfMemory when creating an image

I want to create a BufferedImage in a Java-Application. The users are allowed to change the dimensions of the image and I would like to allow images "as big as possible". How can I check, whether creating the BufferedImage would cause an OutOfMemory-Exception and recover from it?

Try to allocate as much as memory when running application.

-Xms256m -Xmx1024M

Above argument will allocate 1GB memory.

Use Runtime.getRuntime().freeMemory() to check the free memory of your JVM instance. And then based on this value you can add restrictions for dimensions for future image.
