• 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.
Well, per example a resize can be accomplished like this:
BufferedImage bimage = Scalr.resize(bimage, Method.QUALITY, Mode.FIT_EXACT, width, height);
This is just one case, but as you can see in javadoc – http://www.thebuzzmedia.com/downloads/software/imgscalr/javadoc/index.html, this is exactly what you need for cropping, rotating and resizing images.
