MozJpeg4J

This project is based on Mozilla JPEG Encoder (MozJpeg). The original project

is written in C and provides a Java wrapper with the expectation to find a compiled library in the system.

MozJpeg4J simplifies its use in Java by including a set of pre-compiled libraries for Windows, Linux, and Mac.

It also extends the Java wrapper by loading the native OS library and providing utilities for image compression.

Currently default version 3.1 of MozJpeg is embedded into the project.

To build the library or run demo applications, you will need to install Git and

Gradle in your system. Once frameworks are installed, run the following command to clone

the project:

git clone https://github.com/dviktorov/mozjpeg4j.git

Building Java library

To build Java library, run the following command from the cloned project folder:

gradle clean test jar

After the process is finished, the library jar file can be found at ./build/libs of the project

Building OSGi Java library

To build OSGi Java library, run the following command from the cloned project folder:

gradle clean test jarOSGI

After the process is finished, the OSGi library jar file can be found at ./build/libs of the project

Running compression demo gallery

To evaluate the quality of the library you may run the command below. It will compress a set of images and generate

an HTML report at ./build/reports/jpeg_compression. You may open index.html in a browser to view the gallery.

gradle clean test runJpegCompressionDemoApp
