Java port of Lokesh Dhakar Color Thief (grab color palette from an image)

Primary LanguageJava

Java Color Thief

A port to Java of Lokesh Dhakar "Color Thief" for it to be executed server side on a JEE container or in a J2SE app, or in an Android application. See http://lokeshdhakar.com/projects/color-thief/ for more informations and usage example of the javascript version.

⚠️ Note that this is a quick & dirty implementation for the need of a project I worked on few years ago, a better and faster implementation has been developped by Sven Woltmann and is available here, you should definitely check this out.

Example

How to use

See test case included in org.soualid.colorthief.MMCQTest (which is not really what I call a test case, it's a shame but you know, I said it was a quick & dirty implementation 🐽).

Basically :

BufferedImage img = /* read your image here using Image IO */;
// Then get the 10 most used colors palette (first being the dominant color of the image)
List<int[]> result = MMCQ.compute(img, 10); // 10 is the number of dominant colors to find

Will return a list of dominant colors, where each integer array contains the red, green and blue values of each color in the palette.

How to build

As a naive implementation, a prebuilt version of this library has not been made available on maven central or anywhere, but you can build it using Apache Maven, a simple mvn package will build the project, and the install or deploy goals can be used to make the artifact available within your local and/or private repository.

Anyway, I guess you don't really need help on how to use Maven.
