This is a library for comparing images in java. It is based on pdiff with some improvements. The native dependencies are included in the resource folder. If you want to compile the native library for your platform (pdiffLIB) then use cmake to do so. This library is based on the work of Perceptual Image Diff algorithm written in C++

You can use maven to build the library.

• CMake
• A compiler of your choice.

1. Configure the project with cmake.

2. Be sure to have a compiler configured (I recommend MinGw/g++)

3. Set following variables Either use:

   • JDK_PATH - Will try to find out the library path (jvm.lib, jvm.dylib, jvm.so), the include file path (jni.h) and the include file path for the md file (jni_md.h)

   or if the above fails to configure, you can set these three variables:

   • JDK_PATH_INCLUDE_JNI - Path to jni.h
   • JDK_PATH_INCLUDE_JNI_MD - Path to jni_md.h
   • JDK_PATH_LIBRARY - Path to jvm.lib (windows) or jvm.dylib (OS X) or jvm.so (Linux)

4. If you compiled your native library then copy your compiled library to /src/main/resources/natives/{arch}bit/{your library} Where {arch} is the architecture 32bit or 64bit. Be sure that your libary is called either libpdiff.dll, libpdiff.dylib, libpdiff.so.

5. Now you can build your snapshot and use it.
