Best way to read very large images
I have to read some very large png images, say 30000 x 30000 pixels, and chop them into smaller images, say 512 x 512 pieces. Can any one say what is the best method to use. Best meaning lowest memory footprint, and best performance. I would prefer not to have to use any special JAI classes as that would mean my application would need additional packages from the standard j2se installation. However if that's what I gotta do then I suppose I could require their installation.
