java截取图片示例概要.doc

java截取图片示例 这篇文章主要介绍了java截取图片示例,把代码中的图片路径改成自己的图片，运行就可以看到效果了,需要的朋友可以参考下 复制代码 代码如下: /*** */package com.b510; import java.awt.Rectangle;import java.awt.image.BufferedImage;import java.io.File;import java.io.FileInputStream;import java.io.IOException;import java.util.Date;import java.util.Iterator; import javax.imageio.ImageIO;import javax.imageio.ImageReadParam;import javax.imageio.ImageReader;import javax.imageio.stream.ImageInputStream; /*** @date 2012-11-26* @author xhw* */public class ImageCut { /*** 源图片路径名称如:c:\1.jpg*/private String srcpath = e:/poool.jpg;/*** 剪切图片存放路径名称.如:c:\2.jpg*/private String subpath = e:/pool_end;/*** jpg图片格式*/private static final String IMAGE_FORM_OF_JPG = jpg;/*** png图片格式*/private static final String IMAGE_FORM_OF_PNG = png;/*** 剪切点x坐标*/private int x; /*** 剪切点y坐标*/private int y; /*** 剪切点宽度*/private int width; /*** 剪切点高度*/private int height; public ImageCut() { } public ImageCut(int x, int y, int width, int height) {this.x = x;this.y = y;this.width = width;this.height = height;} public static void main(String[] args) throws Exception {ImageCut imageCut = new ImageCut(134, 0, 366, 366);imageCut.cut(imageCut.getSrcpath(), imageCut.getSubpath());} /*** 返回包含所有当前已注册 ImageReader 的 Iterator，这些 ImageReader 声称能够解码指定格式。* 参数：formatName - 包含非正式格式名称 .（例如 jpeg 或 tiff）等 。* * @param postFix* 文件的后缀名* @return*/public IteratorImageReader getImageReadersByFormatName(String postFix) {switch (postFix) {case IMAGE_FORM_OF_JPG:return ImageIO.getImageReadersByFormatName(IMAGE_FORM_OF_JPG);case IMAGE_FORM_OF_PNG:return ImageIO.getImageReadersByFormatName(IMAGE_FORM_OF_PNG);default:return ImageIO.getImageReadersByFormatName(IMAGE_FORM_OF_JPG);}} /*** 对图片裁剪，并把裁剪完蛋新图片保存 。* @param srcpath 源图片路径* @param subpath 剪切图片存放路径* @throws IOException*/public void cut(String srcpath, String subpath) throws IOException {FileInputStream is = null;ImageInputStream iis = null;try {// 读取图片文件is = new FileInp
