    • 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.

    • 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.

    • getSources

      public Vector<RenderedImage> getSources()
      Specified by:
      getSources in interface RenderedImage
      Overrides:
      getSources in class PlanarImage
