如何用java实现图片预览功能，求代码
使用两种不同的方法实现图片预览功能
Java代码
BODY
script language="javascript"
function ShowImage(path){
document.all.divShow.filters.item("DXImageTransform.Microsoft.AlphaImageLoader").src = path;
}
function test(){
document.all.showimg.src=document.all.file1.value;
}
/script
INPUT style="Z-INDEX: 101; LEFT: 232px; POSITION: absolute; TOP: 272px" type="file"onchange="ShowImage(this.value)"
div id="divShow" style="FILTER:progid:DXImageTransform.Microsoft.AlphaImageLoader(sizingMethod=image);WIDTH:274px;HEIGHT:100px"
input type="file" id="file1" onchange="test()"br/
img id="showimg" style="width:200px;height:200px;"
/BODY
"java如何打开本地播放器后自动播放视频文件"
“执行的程序” 文件路径
//注意一：程序的路径要打引号，我的迅雷看看在f盘 ，文件在e盘。
//注意二:程序和文件夹路径中间有个空格.
根据下面的代码自己修改吧
Runtime.getRuntime().exec("\"f:\\Program Files (x86)\\Thunder Network\\Xmp\\Program\\XMP.exe\" e:\\mp4\\high歌.mp4");
用JAVA在界面中实现幻灯片播放，求代码
要让照片随机播放,需要把照片名改成比如photo1.jpg,photo2.jpg,photo3.jpg...的有序号顺序排列的文件名,
然后把改名后的照片文件放到你的项目名的目录下,比如你的项目名叫"slideshow",你就把照片文件放到slideshow文件夹下.
最后把下面的Java程序拷贝到你的项目中,把有DD类名的地方改成你的类名,就行了.
完整的让一些照片在JFrame窗体里自动随机播放的幻灯片程序如下
(我用的图片文件是photo1.jpg,photo2.jpg,photo3.jpg,注意事项在注释中注明
import java.awt.Graphics;
import javax.swing.ImageIcon;
import javax.swing.JFrame;
public class DD extends JFrame implements Runnable{
ImageIcon ii=new ImageIcon("photo1.jpg");//这里换成你的图片文件名,放在你的项目名的文件夹中
DD(){
super("Slide");
setSize(400, 400);
setLocationRelativeTo(null);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setVisible(true);
}
public void paint(Graphics g){
super.paint(g);
g.drawImage(ii.getImage(),0,0,400,400,null);
}
@Override
public void run() {
while(true){
try {
Thread.sleep(500);//这里是幻灯片播放间隔的时间,这里为500毫秒=0.5秒
} catch (InterruptedException e) {
e.printStackTrace();
}
int i=(int)(Math.random()*3)+1;//这里是产生从1-3的随机数,如果你有6个图片文件,把3改成6就是从1-6的随机数了.
ii=new ImageIcon("photo"+i+".jpg");//这里调用你的图片文件,如果你有6个图片文件,改成从1-6的文件名方便调用
this.repaint();
}
}
public static void main(String[] args) {
DD d=new DD();
Thread t=new Thread(d);
t.start();
}
}
请给我的JAVA程序添加一个自动播放图片功能
//其余的类在qq上给你..

怎么让图片在网页里自动播放
那是一个JAVA的图片切换代码，您可以在那些网页的原代码里面找到。
一般循环的图片不超过五张。当然超过是可以的只是要一行一行去写，比较麻烦。代码就不帖了，如果没有从网站里面拷贝出来，也可以加我的QQ来找我。
