GPUImage for Android

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.

Requirements

• Android 2.2 or higher (OpenGL ES 2.0)

Usage

Gradle dependency

repositories {
    mavenCentral()
    maven { url "https://oss.sonatype.org/content/repositories/snapshots/" }
}

dependencies {
    compile 'jp.co.cyberagent.android.gpuimage:gpuimage-library:1.2.3-SNAPSHOT@aar'
}

Sample Code

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);

Gradle

Make sure that you run the clean target when using maven.

gradle clean assemble
