com.sun.media.jai.opimage.OrderedDitherOpImage
| OrderedDitherOpImage | | final class OrderedDitherOpImage extends PointOpImage (Code) | | An OpImage implementing the ordered dither operation as
described in javax.media.jai.operator.OrderedDitherDescriptor.
This OpImage performs dithering of its source image into
a single band image using a specified color cube and dither mask.

| OrderedDitherOpImage | | public OrderedDitherOpImage(RenderedImage source, Map config, ImageLayout layout, ColorCube colorMap, KernelJAI[] ditherMask)(Code) | | Constructs an OrderedDitherOpImage object. May be used to convert a
single- or multi-band image into a single-band image with a color map.
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.
Parameters:
layout - An ImageLayout optionally containing the tile grid layout,SampleModel, and ColorModel, or null.
Parameters:
colorMap - The color map to use which must have a number of bandsequal to the number of bands in the source image. The offset of thisColorCube must be the same for all bands.
Parameters:
ditherMask - An an array of KernelJAI objects thedimension of which must equal the number of bands in the source image.The nth element of the array contains a KernelJAIobject which represents the dither mask matrix for the correspondingband. All KernelJAI objects in the array must have thesame dimensions and contain floating point values between 0.0F and 1.0F. |
| computeRect | | protected void computeRect(Raster[] sources, WritableRaster dest, Rectangle destRect)(Code) | | Computes a tile of the dithered destination image.
Parameters:
sources - Cobbled sources, guaranteed to provide all thesource data necessary for computing the rectangle.
Parameters:
dest - The tile containing the rectangle to be computed.
Parameters:
destRect - The rectangle within the tile to be computed. |
