How can I use this to manipulate Image?

[vxhviet]

Hi,
I would like to ask how can I use this lib to manipulate image (brightness, contrast, etc..) as in the original android-gpuimage project. For example, I used to do this:

        mGPUImage = new GPUImage(mContext);
        mGPUImage.setGLSurfaceView(mSurface);
        mGPUImage.setScaleType(GPUImage.ScaleType.CENTER_INSIDE);
        mGPUImage.setImage(mUri);
       
        final GPUImageContrastFilter contrastFilter = new GPUImageContrastFilter(1.0f);
        mGPUImage.setFilter(contrastFilter);

        .....
      
        contrastFilter.setContrast(contrastValue);
        mGPUImage.requestRender();

However, after digging around the lib, I can't find GPUImage anywhere.

Another question, I'm looking for another lib mostly because of this unresolved bug. I would like to ask is this fixed with this current release?

Thank you so much for your time.

oops, i haven't notice it. ;p
thx for you bug report. sure there is a bug here. I think I just reconstruct the original project but seem forgot to forge the pure image operate.
This problem will fix in next release. So, if u want to use this lib to render a single image, i suggest u use original project, or wait my next release.
For now, this project can only handle condition with using camera state.

Now I'm handle this problem.

done, now u can use this like:

@Override
public void onCreate(final Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity);

    // prepare surface.
    mRecorderViews = (FilterRecoderView) findViewById(R.id.vp_video_recorder_gl);
    
    // prepare the filter you want to use
    final GPUImageContrastFilter contrastFilter = new GPUImageContrastFilter(1.0f);
    contrastFilter.setContrast(contrastValue);
    
    // bind to PureImageManager and render
    PureImageManager.init(context)
                    .setGLSurfaceView(mRecorderViews)
                    .setScaleType(GPUImage.ScaleType.CENTER_INSIDE)
                    .setImage(mUri)
                    .setFilter(contrastFilter)
                    .requestRender();
}
