Idea from: iOS GPUImage framework
Goal is to have something as similar to GPUImage as possible. Vertex and fragment shaders are exactly the same. That way it makes it easier to port filters from GPUImage iOS to Android.
- Android 2.2 or higher (OpenGL ES 2.0)
GPUImage can be used as a library project or by copying the following files/folders to your libs folder.
- library/libs/armeabi (only needed for camera live preview)
- library/bin/gpuimage.jar
<dependency>
<groupId>jp.co.cyberagent.android.gpuimage</groupId>
<artifactId>gpuimage-library</artifactId>
<type>apklib</type>
<version>(use current version here)</version>
</dependency>
If you want to use it with live camera preview, than you will need to add the following as well:
<dependency>
<groupId>jp.co.cyberagent.android.gpuimage</groupId>
<artifactId>gpuimage-library</artifactId>
<classifier>armeabi</classifier>
<type>so</type>
<version>(use current version here)</version>
</dependency>
With preview:
@Override
public void onCreate(final Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity);
Uri imageUri = ...;
mGPUImage = new GPUImage(this);
mGPUImage.setGLSurfaceView((GLSurfaceView) findViewById(R.id.surfaceView));
mGPUImage.setImage(imageUri); // this loads image on the current thread, should be run in a thread
mGPUImage.setFilter(new GPUImageSepiaFilter());
// Later when image should be saved saved:
mGPUImage.saveToPictures("GPUImage", "ImageWithFilter.jpg", null);
}
Without preview:
Uri imageUri = ...;
mGPUImage = new GPUImage(context);
mGPUImage.setFilter(new GPUImageSobelEdgeDetection());
mGPUImage.setImage(imageUri);
mGPUImage.saveToPictures("GPUImage", "ImageWithFilter.jpg", null);
Run the following command in the library folder. Make sure you have android-ndk in your PATH.
cd library
ndk-build
Make sure that you run the clean target when using maven.
mvn clean install
