Usage

From source file:com.badlogic.gdx.tests.PremultiplyAlpha.java

private void gpuPremultiplyAlpha(String in, String out) {
    Texture texture = new Texture(Gdx.files.absolute(in));
    texture.setFilter(TextureFilter.Nearest, TextureFilter.Nearest);
    FrameBuffer buffer = new FrameBuffer(Format.RGBA8888, texture.getWidth(), texture.getHeight(), false);
    buffer.getColorBufferTexture().setFilter(TextureFilter.Nearest, TextureFilter.Nearest);
    ShaderProgram shader = new ShaderProgram(VERTEX_SHADER, FRAG_SHADER);
    Gdx.app.log("Log", shader.getLog());
    SpriteBatch batch = new SpriteBatch(10);
    batch.getProjectionMatrix().setToOrtho2D(0, 0, texture.getWidth(), texture.getHeight());
    batch.disableBlending();//from  w ww  .j  a  va2 s . c  om
    batch.setShader(shader);

    //Premultiply
    buffer.begin();
    Gdx.gl.glClearColor(0, 0, 0, 0);
    Gdx.gl.glClear(GL20.GL_COLOR_BUFFER_BIT);
    batch.begin();
    batch.draw(texture, 0, 0);
    batch.end();
    Pixmap pixmap = ScreenUtils.getFrameBufferPixmap(0, 0, texture.getWidth(), texture.getHeight());
    buffer.end();

    //Save
    PixmapIO.writePNG(Gdx.files.absolute(out), pixmap);
    buffer.dispose();
    texture.dispose();
    pixmap.dispose();
    Gdx.app.exit();
