java实现gif图片剪裁

        <dependency>            <groupId>javax.media</groupId>            <artifactId>jai-core</artifactId>            <version>1.1.3</version>        </dependency>

在功能实现之后，作者将自己的修改新建了一个包。如图：

/** * @param args * @throws Exception */public static void main(String[] args) throws Exception {    try {        // 起始坐标，剪切大小        int x = 0;        int y = 0;        int width = 100;        int height = 100;        // 参考图像大小        int clientWidth = 300;        int clientHeight = 250;

        File file = new File("C:\\Users\\tianjingle\\Desktop\\0.gif");        BufferedImage image = ImageIO.read(file);        double destWidth = image.getWidth();        double destHeight = image.getHeight();
        if(destWidth < width || destHeight < height) {            throw new Exception("源图大小小于截取图片大小!");        }
        double widthRatio = destWidth / clientWidth;        double heightRatio = destHeight / clientHeight;
        x = Double.valueOf(x * widthRatio).intValue();        y = Double.valueOf(y * heightRatio).intValue();        width = Double.valueOf(width * widthRatio).intValue();        height = Double.valueOf(height * heightRatio).intValue();
        System.out.println("裁剪大小  x:" + x + ",y:" + y + ",width:" + width + ",height:" + height);        float ratio = ((float) image.getWidth()) / image.getWidth();        String formatName = "gif";        String pathSuffix = "." + formatName;        String pathPrefix = "C:\\Users\\tianjingle\\Desktop\\";        String targetPath = pathPrefix  + System.currentTimeMillis() + pathSuffix;        byte[] target = ImageUtils.cutImage(new FileInputStream(file.getPath()), "gif", x , y , width, height,ratio);        FileUtils.writeByteArrayToFile(new File(targetPath),target);    } catch (IOException e) {        e.printStackTrace();    }}
