完整代码如下：

1、主要方法编写类

package chapter4;

import java.awt.image.BufferedImage;

public class BSCAdjustFilter extends AbstractBufferedImageOp {

private double brightness;

private double contrast;

private double saturation;

public double getBrightness() {

return brightness;

}

public void setBrightness(double brightness) {

this.brightness = brightness;

}

public double getSaturation() {

return saturation;

}

public void setSaturation(double saturation) {

this.saturation = saturation;

}

public double getContrast() {

return contrast;

}

public void setContrast(double contrast) {

this.contrast = contrast;

}

public BufferedImage filter(BufferedImage src,BufferedImage dest){

handleParameters();//调整各系数取值范围

int width = src.getWidth();

int height = src.getHeight();

if(dest == null){

dest = creatCompatibleDestImage(src,null);

}

int[] inpixels = new int[width*height];

int[] outpixels = new int[width*height];

getRGB(src,0,0,width,height,inpixels);

int index = 0;

for(int row=0;row

int ta = 0,tr = 0,tg = 0,tb = 0;

for(int col=0;col

index = row*width+col;

ta = (inpixels[index] >> 24) & 0xff;

tr = (inpixels[index] >> 16) & 0xff;

tg = (inpixels[index] >> 8) & 0xff;

tb = inpixels[index] & 0xff;

//RGB转换为HSL色彩空间

double[] hsl = rgb2Hsl(new int[]{tr,tg,tb});

//调整饱和度

hsl[1] = hsl[1]*saturation;

if(hsl[1]<0.0){

hsl[1] = 0.0;

}

if(hsl[1]>255.0){

}

//调整亮度

hsl[2] = hsl[2]*brightness;

if(hsl[2]<0.0){

hsl[2] = 0.0;

}

if(hsl[2]>255.0){

hsl[2] = 255.0;

}

//HSL转换为rgb空间

int[] rgb = hsl2RGB(hsl);

tr = clamp(rgb[0]);

tg = clamp(rgb[1]);

tb = clamp(rgb[2]);

//调整对比度

double cr = ((tr/255.0d)-0.5d)*contrast;

double cg = ((tg/255.0d)-0.5d)*contrast;

//输出RGB值

tr = (int)((cr+0.5f)*255.0f);

tg = (int)((cg+0.5f)*255.0f);

tb = (int)((cb+0.5f)*255.0f);

outpixels[index] = (ta << 24) | (clamp(tr) << 16 ) | (clamp(tg) << 8) | clamp(tb);

}

}

setRGB(dest,0,0,width,height,outpixels);

return dest;

}

public void handleParameters(){

contrast = (1.0+contrast/100.0);

brightness = (1.0 +brightness/100.0);

saturation = (1.0+saturation/100.0);

}

public int clamp(int value){

return value>255 ? 255:((value<0) ? 0:value);

}

}
