    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.
