Description copied from class: RasterDataNodeOpImage

Computes the target pixel data for this level image.

Specified by:

computeProductData in class RasterDataNodeOpImage

Parameters:

destData - The target pixel buffer to write to. The number of elements in this buffer will always be region.width * region.height.

destRect - The target region in pixel coordinates valid for this image level.

Throws:

IOException - May be thrown if an I/O error occurs during the computation.
