computeProductData
protected void computeProductData(ProductData productData, Rectangle destRect) throws IOException
Description copied from class:RasterDataNodeOpImage
Computes the target pixel data for this level image.- Specified by:
computeProductData
in classRasterDataNodeOpImage
- Parameters:
productData
- The target pixel buffer to write to. The number of elements in this buffer will always beregion.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.
-
computeSample
protected abstract double computeSample(int sourceX, int sourceY)
Computes the sample value at the given source pixel coordinatessourceX
andsourceY
.- Parameters:
sourceX
- The source pixel X coordinate of the sample to be computed.sourceY
- The source pixel Y coordinate of the sample to be computed.- Returns:
- The sample value.
