Usage

From source file:net.d53dev.dslfy.web.service.GifService.java

public void saveAnimatedGIF(OutputStream out, List<GifFrame> frames, int loopCount) throws Exception {
    ImageWriter iw = ImageIO.getImageWritersByFormatName("gif").next();

    ImageOutputStream ios = ImageIO.createImageOutputStream(out);
    iw.setOutput(ios);//from ww w.  ja  va 2  s.co  m
    iw.prepareWriteSequence(null);

    int p = 0;
    for (GifFrame frame : frames) {
        ImageWriteParam iwp = iw.getDefaultWriteParam();
        IIOMetadata metadata = iw.getDefaultImageMetadata(new ImageTypeSpecifier(frame.img), iwp);
        this.configureGIFFrame(metadata, String.valueOf(frame.delay / 10L), p++, frame.disposalMethod,
                loopCount);
        IIOImage ii = new IIOImage(frame.img, null, metadata);
        iw.writeToSequence(ii, null);
    }

    iw.endWriteSequence();
