Java绘制GIF [英] Java Draw a GIF

问题描述

我正在尝试使用Java Graphics API绘制GIF，但无法使用下面的代码成功绘制GIF.仅绘制了GIF的第一张图片或缩略图，但无法播放.

I'm trying to draw a GIF using the Java Graphics API, but I'm not able to successfully draw a GIF using my below code. Only the first image or thumbnail of the GIF is drawn but it doesn't play.

public void paintComponent(Graphics g){
    super.paintComponent(g);
    BufferedImage img = null;
    try {
        URL url = new URL("GIF URL");
        img = ImageIO.read(url);
    } catch (Exception e) {
    }       
    g.drawImage(img, 5, 5, this);
}

基本上，我正在为登录屏幕创建图形，并且想要绘制一个循环的GIF.

Essentially I am creating graphics for a login screen and I want to draw a GIF that loops.

更新了我的代码并稍微更改了问题.

Updated my code and changed the question a bit.

推荐答案

您可以将gif加载到BufferedImage对象中. 然后我们将缓冲的图像绘制到您的swing组件上

You can load a gif into a BufferedImage object. Then we paint the buffered image onto your swing component

还必须更好地重写paintComponent方法

Also one must better override the paintComponent method
