      • TransparencyFillOpImage

        public TransparencyFillOpImage​(RenderedImage source,
                               BorderExtender extender,
                               TransparencyFillDescriptor.FillType type,
                               Map config,
                               ImageLayout layout,
                               Number noData,
                               Integer width)
        Creates a TransparencyFillOpImage given a ParameterBlock containing the image source. The image dimensions are derived from the source image. The tile grid layout, SampleModel, and ColorModel may optionally be specified by an ImageLayout object.
        Parameters:
        source - a RenderedImage.
        extender - a BorderExtender, or null.
        type - a TransparencyFillDescriptor.FillType type to be used for transparency filling
        layout - an ImageLayout optionally containing the tile grid layout, SampleModel, and ColorModel, or null.

    • Method Detail

      • computeRect

        protected void computeRect​(Raster[] sources,
                           WritableRaster dest,
                           Rectangle destRect)
        Performs fill on a specified rectangle. The sources are cobbled.
        Overrides:
        computeRect in class OpImage
        Parameters:
        sources - an array of source Rasters, guaranteed to provide all necessary source data for computing the output.
        dest - a WritableRaster tile containing the area to be computed.
        destRect - the rectangle within dest to be processed.
