Constructor Detail

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.

getSources

public Vector<RenderedImage> getSources()

Specified by:

getSources in interface RenderedImage

Overrides:

getSources in class PlanarImage
