JAVA实现图片处理缩略图-三种开源实现方式

代码实现如下：

第一个开源: Thumbnailator

long begin = System.currentTimeMillis();

try {

Thumbnails.of(new File("E:\\test\\photos\\亲密敌人.jpg"))

.size(300, 200)

//.rotate(90)

.outputQuality(0.8f)

.toFile(new File("E:\\000.jpg"));

} catch (IOException e) {

e.printStackTrace();

}

long end = System.currentTimeMillis();

System.out.println(end - begin);

第二个开源: java-image-scaling

long begin2 = System.currentTimeMillis();

File fileOne = new File("E:\\test\\photos\\阿凡达.jpg"); ? ?

File hd_ad = new File("E:\\test\\data\\高清页面-广告图片.jpg");?

try {

BufferedImage bufferedImage11 = new ThumpnailRescaleOp(1104,540).doFilter(ImageIO.read(fileOne),null,1104, 540);

ImageIO.write(bufferedImage11, "jpg", hd_ad);

} catch (IOException e) {

e.printStackTrace();

}

long end2 = System.currentTimeMillis();

System.out.println(end2-begin2);

第三个开源: EasyImage

long begin3 = System.currentTimeMillis();

Image image2 ?= new Image("E:\\test\\photos\\亲密敌人.jpg");

image2.resize(290, 400);

image2.saveAs("e:\\222.jpg");

long end3 = System.currentTimeMillis();

System.out.println(end3 - begin3);

//融合两张图片

Image image3 ?= new Image("E:\\test\\photos\\亲密敌人.jpg");

image3.combineWithPicture("E:\\test\\photos\\泰坦尼克号.jpg");

image3.saveAs("E:\\333.jpg");

//强调图像的某个部分：

Image image4 ?= new Image("E:\\test\\photos\\亲密敌人.jpg");

image4.emphasize(250, 200, 2300, 500);

image4.saveAs("E:\\444.jpg");
