Description 

Enhance JP2KAK driver to support writting/compressing very large images by 
dividing large images into multiple small tiles, and compressing one tile at 
time.

Change History

Changed 7 years ago by warmerdam 

I have modified the JP2KAK driver to support the BLOCKXSIZE and BLOCKYSIZE
creation options to control tile size.  By default it now starts producing
multiple tiles if the image width is larger than 25000, and base memory use
seems to be under 60MB even for very large images using this constraint.
