哪里有JAVA写的类似QQ截图工具的源代码?不能立即给你提供源码但是可以教给你怎么实现 。
首先 你要截屏 肯定要在属于用鼠标圈定一个区域来截取这个区域 。
你可以这样：
先截取当前屏幕java截图软件代码的满屏图片：new robot().createScreenCapture(r) 这个是截屏代码r是Rectangle类型代表要截取的区域 。
然后用 JDialog 做一个无控制条的窗口，大小设置成满屏，把截取的这个满屏的图片贴到这个 JDiaglog 里
然后做一下鼠标圈定区域 ， 这个很简单 不详细说了，最后对你圈定的这个区域再做一次截屏，这个不就是你要的截图了 。， 。最后别忘了 截屏完毕后 关闭JDialog
你要是觉得这样做麻烦，也没别的办法 。反正java截图软件代码我很明白 QQ的截屏也是这样做的
java 实现截屏！主要是利用java的几个先有的函数，如Robot这个类的一个方法createScreenCapture一个获得一个任意大小的屏幕图像（在这里是全屏图像） ， 而所谓的截图就是在这个图像上画出一个矩形，再利用上面的方法获得这部分的图像，程序中的cf.setAlwaysOnTop(true)是必需的;看起来是在屏幕上截图，其实只是在一个在一个内镶有桌面背景的JFrame中截图 。不知道还有没有其他的好方法~
附上代码：

import java.awt.event.*;
import java.io.File;
import javax.imageio.ImageIO;
import javax.swing.*;
public class Camera {
/**

getContentPane().add(new CameraJPanel());
}
class CameraJPanel extends JPanel implements MouseListener,MouseMotionListener

如何以Java实现网页截图技术事实上，如果您想以Java实现网页截图，也就是“输入一段网址，几秒钟过后就能截取一张网页缩略图”的效果 。那么，您至少有3种方式可以选择 。
1、最直接的方式——使用Robot
方法详解：该方法利用Robat提供的强大桌面操作能力，硬性调用浏览器打开指定网页，并将网页信息保存到本地 。
优势：简单易用 ， 不需要任何第三方插件 。
缺点：不能同时处理大量数据，技术含量过低，属于应急型技巧 。
实现方法：使用如下代码即可 。
[java] view plaincopy
public static void main(String[] args) throws MalformedURLException,
IOException, URISyntaxException, AWTException {
//此方法仅适用于JdK1.6及以上版本
Desktop.getDesktop().browse(
new URL("").toURI());
Robot robot = new Robot();
robot.delay(10000);
Dimension d = new Dimension(Toolkit.getDefaultToolkit().getScreenSize());
int width = (int) d.getWidth();
int height = (int) d.getHeight();
//最大化浏览器
robot.keyRelease(KeyEvent.VK_F11);
robot.delay(2000);
Image image = robot.createScreenCapture(new Rectangle(0, 0, width,
height));
BufferedImage bi = new BufferedImage(width, height,
BufferedImage.TYPE_INT_RGB);
Graphics g = bi.createGraphics();
g.drawImage(image, 0, 0, width, height, null);
//保存图片
ImageIO.write(bi, "jpg", new File("google.jpg"));
}
2、最常规的方式——利用JNI，调用第三方C/C组件
方法详解：目前来讲，Java领域对于网页截图组件的开发明显不足（商机？），当您需要完成此种操作时 ， 算得上碰到了Java的软肋 。但是 ， 众所周知Java也拥有强大的JNI能力 ， 可以轻易将C/C开发的同类组件引为己用 。不懂可以扣五七八零二四一四四
优势：实现简单，只需要封装对应的DLL文件，就可以让Java实现同类功能 。
劣势：同其他JNI实现一样，在跨平台时存在隐患，而且您的程序将不再属于纯Java应用 。
实现方法：可参见此用例 ， 具体封装何种C/C组件请自行选择 。
PS：示例来源于ACA HTML to Image Converter项目（ ） ， 这是一个收费的HTML转Image第三方组件，但封装方式在Java中大同小异 。
引用JNI封装：
[java] view plaincopy
import sun.awt.*;
import java.awt.*;
import javax.swing.*;
import java.awt.event.*;
import java.awt.*;
import java.awt.peer.*;
public class Snap
{
static
{
System.loadLibrary("Snap");
}
public static void main( String[] argv )
{
Snap t_xSnap = new Snap();
t_xSnap.Start("", "snapshot-google.png");
}
public native void Start(String pi_strURL, String pi_strImageName);
}
CPP部分的实现：
[java] view plaincopy
#include windows.h
#include atlbase.h
#include "snap.h"
#pragma comment(lib,"atl.lib")
#import "./../../acawebthumb.dll" no_namespace
JNIEXPORT void JNICALL Java_Snap_Start(JNIEnv *pEnv, jobject, jstring pi_strUrl, jstring pi_strFileName)
{
CoInitialize(0);
_bstr_t t_strUrl = pEnv-GetStringUTFChars(pi_strUrl, 0);
_bstr_t t_strFileName = pEnv-GetStringUTFChars(pi_strFileName, 0);
IThumbMakerPtr HTML_Converter = NULL;
HRESULT hr = HTML_Converter.CreateInstance(L"ACAWebThumb.ThumbMaker");
if (SUCCEEDED(hr))
{
HTML_Converter-SetURL(t_strUrl);
if ( 0 == HTML_Converter-StartSnap() )
HTML_Converter-SaveImage(t_strFileName);
}
if (HTML_Converter)
HTML_Converter.Release();
CoUninitialize();
}
以该组件图像化yahoo界面的效果图：
3、最扎实的方法——自行解析HTML标记，并将其图像化
方法详解：众所周知，HTML之所以在浏览器中以具体的网页格式出现，并非服务器端传了一整个应用到客户端，而是源自于浏览器对于客户端自行解析的结果 。因此 ， 只要我们将对应的解析一一实现 ， 那么将网页图形化，就将不是什么难事 。
优势：纯Java实现，一劳永逸 ， 一旦开发完成则永远通用，而且有一定的商用价值 。
劣势：开发费时，且需要针对不同语法做精确分析 ， 才能保证输出的基本正确 。尤其在涉及到JavaScript解析时，难度将尤其增大 。
实现方法：目前尚无具体案例可供参考 。但是，由于Java有jdic之类的浏览器项目存在（） ， 而Java图形界面又属绘制生成 。从理论上说，我们可以将所有具备Graphics的组件图形化保存 。
而如果自行解析，那么您需要建立HTML解析器（或使用第三方的，万幸Java在这方面的组件很多），了解Java2D机制，了解何时该使用drawString绘制文字，何时又该使用drawImage插入图片等等 。
谢谢采纳！
Java如何实现截图功能下面给你介绍将全屏幕截图保存到指定目录下的代码，希望能对你有帮助：
核心代码为：snapShot方法中的相关逻辑
package Jietu;
import java.awt.Dimension;
import java.awt.Rectangle;
import java.awt.Robot;
import java.awt.Toolkit;
import java.awt.image.BufferedImage;
import java.io.File;
import javax.imageio.ImageIO;
public class CameraTest {
private String filePreStr; // 默认前缀（选择存储路径例如： D：\\）
private String defName = "cameraImg";// 默认截图名称
static int serialNum = 0;//截图名称后面的数字累加
private String imageFormat; // 图像文件的格式
private String defaultImageFormat = "png"; //截图后缀
Dimension d = Toolkit.getDefaultToolkit().getScreenSize(); //获取全屏幕的宽高尺寸等数据
public CameraTest() {
filePreStr = defName;
imageFormat = defaultImageFormat;
}
public CameraTest(String s, String format) {
filePreStr = s;
imageFormat = format;
}
public void snapShot() {
try {
// *** 核心代码 *** 拷贝屏幕到一个BufferedImage对象screenshot
BufferedImage screenshot = (new Robot()).createScreenCapture(new Rectangle(0, 0, (int) d.getWidth(), (int) d.getHeight()));
serialNum;
// 根据文件前缀变量和文件格式变量 ， 自动生成文件名
String name = filePreStrString.valueOf(serialNum)"."imageFormat;
File f = new File(name);
System.out.print("Save File "name);
// 将screenshot对象写入图像文件
ImageIO.write(screenshot, imageFormat, f);
System.out.print("..Finished!\n");
} catch (Exception ex) {
System.out.println(ex);
}
}
// 运行之后，即可将全屏幕截图保存到指定的目录下面br // 配合前端页面上面的选择尺寸等逻辑，传到后台，即可实现自由选择截图区域和大小的截图br
public static void main(String[] args) {
CameraTest cam = new CameraTest("d:\\Hello", "png");//
cam.snapShot();
}
}
java 怎么实现网页截图代码如下
[java]
span style="font-size:18px;"package com.util;

import java.awt.Dimension;
import java.awt.Graphics;

import java.awt.event.KeyEvent;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import java.net.URISyntaxException;
import java.net.URL;
import javax.imageio.ImageIO;
public class CutPicture {
public static void main(String[] args) throws Exception,
IOException, URISyntaxException, AWTException {
// 此方法仅适用于JdK1.6及以上版本
Desktop.getDesktop().browse(new URL("").toURI());
Robot robot = new Robot();
robot.delay(10000);
Dimension d = new Dimension(Toolkit.getDefaultToolkit().getScreenSize());
int width = (int) d.getWidth();
int height = (int) d.getHeight();
// 最大化浏览器
robot.keyRelease(KeyEvent.VK_F11);
robot.delay(2000);
Image image = robot.createScreenCapture(new Rectangle(0, 0, width,height));
BufferedImage bi = new BufferedImage(width, height,
BufferedImage.TYPE_INT_RGB);
Graphics g = bi.createGraphics();
g.drawImage(image, 0, 0, width, height, null);
// 保存图片
ImageIO.write(bi, "jpg", new File("c:/open.jpg"));
}
}/span
