    • 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 class RasterDataNodeOpImage
      Parameters:
      productData - 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.

    • computeSample

      protected abstract double computeSample(int sourceX, int sourceY)
      Computes the sample value at the given source pixel coordinates sourceX and sourceY.
      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.
