typedef enum tagJ2KREGIONOFINTEREST
{
J2K_USE_LEAD_REGION, // Use the LEAD bitmap region to
define
// the region of interest
J2K_USE_OPTION_RECT // Use the rectangle specified in
the rcROI

} J2KREGIONOFINTEREST, * 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.
