有沒有辦法從Java中的多個圖像創建一個Gif圖像？

Question

我試圖設置一個簡單的Java程序，從多個其他圖像（JPG）創建一個單一的動畫GIF。任何人都可以給我一個如何在Java中實現這個鉤子？我已經搜索谷歌，但找不到任何真正有用的東西。

謝謝你們！

在這裏，你有一個創建不同圖像的gif動畫類的例子：

這個類提供了這些方法：

class GifSequenceWriter { 
    public GifSequenceWriter(
     ImageOutputStream outputStream, 
     int imageType, 
     int timeBetweenFramesMS, 
     boolean loopContinuously); 

    public void writeToSequence(RenderedImage img); 

    public void close(); 
} 

，也是一個小例子：

public static void main(String[] args) throws Exception { 
    if (args.length > 1) { 
    // grab the output image type from the first image in the sequence 
    BufferedImage firstImage = ImageIO.read(new File(args[0])); 

    // create a new BufferedOutputStream with the last argument 
    ImageOutputStream output = 
     new FileImageOutputStream(new File(args[args.length - 1])); 

    // create a gif sequence with the type of the first image, 1 second 
    // between frames, which loops continuously 
    GifSequenceWriter writer = 
     new GifSequenceWriter(output, firstImage.getType(), 1, false); 

    // write out the first image to our sequence... 
    writer.writeToSequence(firstImage); 
    for(int i=1; i<args.length-1; i++) { 
     BufferedImage nextImage = ImageIO.read(new File(args[i])); 
     writer.writeToSequence(nextImage); 
    } 

    writer.close(); 
    output.close(); 
    } else { 
    System.out.println(
     "Usage: java GifSequenceWriter [list of gif files] [output file]"); 
    } 
}
