ci压缩图片

1. java截取图片

呵呵,很明确的告诉你：可以！

代码半小时后出来！！！

……

终于出来了（呵呵，好像超过了半小时哈）且看代码：

importjava.awt.Color;

importjava.awt.Graphics;

importjava.awt.image.BufferedImage;

importjava.io.File;

importjava.io.IOException;

importjavax.imageio.ImageIO;

importjavax.swing.JApplet;

publicclassTestextendsJApplet{

Stringaddrs="F:\images\mm.bmp";//改成自己的图片路径

BufferedImagemm,child;

CutImageci;

publicTest(){

try{

mm=ImageIO.read(newFile(addrs));

}catch(IOExceptione){

System.out.println("图片读取失败！");

e.printStackTrace();

}

ci=newCutImage(mm);

child=ci.getChildImage(50,0,150,220);

}

publicvoidinit(){

}

publicvoidpaint(Graphicsg){

g.setColor(Color.red);

g.drawString("原图：",0,10);

g.drawImage(mm,20,10,this);

g.drawString("ci.getChildImage(50,0,150,220)截取后的图片",mm.getWidth()+30,10);

g.drawImage(child,mm.getWidth()+50,20,this);

}

}

importjava.awt.Image;

importjava.awt.image.BufferedImage;

publicclassCutImage{

privateBufferedImageimg;

privateBufferedImagechild;

publicCutImage(){

}

publicCutImage(BufferedImageim){

img=im;

}

publicCutImage(Imageim){

img=(BufferedImage)im;

}

publicvoidsetImg(BufferedImageimg){

this.img=img;

}

(intx,inty,intwidth,intheight){

intcw=width;

intch=height;

intpw=img.getWidth();

intph=img.getHeight();

if(pw<x+width){

System.out.println("给出的参数超出原图片的范围！程序会自动减小宽度或高度");

cw=pw-x;

}

if(ph<y+height){

System.out.println("给出的参数超出原图片的范围！程序会自动减小宽度或高度");

ch=ph-y;

}

child=newBufferedImage(cw,ch,BufferedImage.TYPE_INT_ARGB);

for(inti=0;i<ch;i++){

for(intj=0;j<cw;j++){

child.setRGB(j,i,img.getRGB(x+j,y+i));

}

}

returnchild;

}

}

呵呵，希望楼主能够满意哦，如果你愿意的话，稍微改一下代码就可以把截取的图片child报春到你的电脑上了。下面程序的运行效果吧！
