Constructor Detail

FillConstantOpImage

public FillConstantOpImage(RenderedImage sourceImage,
                           RenderedImage maskImage,
                           Number fillValue)

Where the mask image is set the original values in the source image are preserved. Otherwise the values are replaced by the no-data value.

Parameters:

sourceImage - The source image.

maskImage - The mask image. This mask prevents pixel values from being overwritten by fill value (where mask != 0).

fillValue - The value to replace the original ones.
