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。
