CamanJ

This is an early port of the JS image manipulation library CamanJS to Java. There is still a lot of room for improvement and not all functionality has been ported over yet; however, CamanJ is quickly improving in speed and memory management.

Both suggestions and contributions are welcome!

Latest Benchmarks

All benchmarks are run against an image of size 3872x2592 using the Example.java program.

Mac OSX

• Test CPU: Intel Core i7 2.66GHz (dual-core with hyperthreading)
• Render time: ~1880ms

Windows 7

• Test CPU: Intel Core i7 2.75GHz (quad-core with hyperthreading)
• Render time: ~1100ms

Example Usage

// Load CamanJ with our image
CamanJ caman = new CamanJ("images/example1.jpg");

// Apply the brightness and contrast filters
caman.filter("brightness").set(30);
caman.filter("contrast").set(10);

// Apply a preset too if you want
caman.preset("lomography");

// Output the modified image to a new file
caman.save("output/example1.jpg");

Goals

• Similar interface to the original CamanJS library
• Very simple to use for image manipulation
• Extremely fast with the ability to handle very large images
• Android compatibility
• Easily extensible with new funcitonality (e.g. with JARs and ServiceLoader)
