imgscalr 是一個對圖片進行縮放的 Java 類庫。

100% Java code based on Java2D, no native libraries to install
Java that works in “headless” environments without special environment variable settings; it just works.
Because there are no native libraries, you mitigate the risk of native libraries crashing the host VM (e.g. your app server) or thread-contention issues
Hardware accelerated on supported platforms (uses the optimized Java2D rendering pipeline)
Fast; not faster than a native-C solution, but still damn fast.
Simple, simple, simple. A handful of static, 1-word methods you can call. No complex configurations, managers, encoders/decoders or any other nonsense. imgscalr is not a “graphics library”, it is a set of the most commonly used graphic operations, optimized and ready to do your bidding.

import static org.imgscalr.Scalr.*;

public static BufferedImage createThumbnail(BufferedImage img) {
  // Create quickly, then smooth and brighten it.
  img = resize(img, Method.SPEED, 125, OP_ANTIALIAS, OP_BRIGHTER);

  // Let's add a little border before we return result.
  return pad(img, 4);
}
