Class BufferedImageFilter

Implemented Interfaces:
Cloneable, ImageConsumer
public class BufferedImageFilter
extends ImageFilter
implements Cloneable
The BufferedImageFilter class wraps BufferedImageOp objects in a Filter. When pixels are pushed through the filter, we create a BufferedImage, apply the BufferedImageOp, and pass the filtered pixels to the base class.

Fields inherited from class java.awt.image.ImageFilter

consumer

Fields inherited from interface java.awt.image.ImageConsumer

COMPLETESCANLINES, IMAGEABORTED, IMAGEERROR, RANDOMPIXELORDER, SINGLEFRAME, SINGLEFRAMEDONE, SINGLEPASS, STATICIMAGEDONE, TOPDOWNLEFTRIGHT

Constructor Summary

BufferedImageFilter(BufferedImageOp op)

Method Summary

BufferedImageOp
getBufferedImageOp()
void
setPixels(int x, int y, int w, int h, ColorModel model, byte[] pixels, int off, int scansize)
This function delivers a rectangle of pixels where any pixel(m,n) is stored in the array as a byte at index (n * scansize + m + offset).
