} J2KREGIONOFINTEREST, L_FAR* pJ2KREGIONOFINTEREST;

The J2KREGIONOFINTEREST data type is used within the FILEJ2KOPTIONS structure to indicate how to define the region of interest.

Comments

If J2K_USE_LEAD_REGION is used, then any region shape is acceptable. It will be converted internally by the filter to a rectangle.
