Java Source Code / Java Documentation » 6.0 JDK Modules » Java Advanced Imaging » com.sun.media.jai.opimage   Source Cross Reference   Class Diagram   Java Document (Java Doc)   javax.media.jai.OpImage    javax.media.jai.AreaOpImage       com.sun.media.jai.opimage.GradientOpImage GradientOpImage final class GradientOpImage extends AreaOpImage (Code) An OpImage class to perform Gradient operation on a source image. The Kernels cannot be bigger in any dimension than the image data. See Also:   KernelJAI Field Summary protected  KernelJAI kernel_hkernel_v      The kernel with which to do the gradient operation. Constructor Summary public   GradientOpImage(RenderedImage source, BorderExtender extender, Map config, ImageLayout layout, KernelJAI kernel_h, KernelJAI kernel_v)      Creates a GradientOpImage given the image source and the pair of orthogonal gradient kernels. Method Summary protected  void computeRect(Raster[] sources, WritableRaster dest, Rectangle destRect)      Performs gradient operation on a specified rectangle. Field Detail kernel_hkernel_v protected KernelJAI kernel_hkernel_v(Code) The kernel with which to do the gradient operation. Constructor Detail GradientOpImage public GradientOpImage(RenderedImage source, BorderExtender extender, Map config, ImageLayout layout, KernelJAI kernel_h, KernelJAI kernel_v)(Code) Creates a GradientOpImage given the image source and the pair of orthogonal gradient kernels. 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:   extender - a BorderExtender, or null. Parameters:   layout - an ImageLayout optionally containing the tile grid layout,SampleModel, and ColorModel, or null. Parameters:   kernel_h - the horizontal kernel. Parameters:   kernel_v - the vertical kernel Method Detail computeRect protected void computeRect(Raster[] sources, WritableRaster dest, Rectangle destRect)(Code) Performs gradient operation on a specified rectangle. The sources are cobbled. Parameters:   sources - an array of source Rasters, guaranteed to provide allnecessary source data for computing the output. Parameters:   dest - a WritableRaster tile containing the area to be computed. Parameters:   destRect - the rectangle within dest to be processed.
