It's easy to use, you just send operators to IEManager instance, and all is done!

For example, add lut filer to image like this:

1. create an operator

filterOp = new LookupFilterOperator.Builder()
                            .intensity(INTENSITY_VALUE)
                            .lookup(BitmapFactory.decodeStream(LOOK_UP_TABLE_STREAM)
                            .build();

2. add to IEManager api class

if (opAdded) {
    // you can render it right now.
    IEManager.getInstance().updateOperator(0, filterOp, true);
    // or render it later.
    IEManager.getInstance().updateOperator(0, filterOp, false);
} else {
    IEManager.getInstance().addOperator(0, filterOp, true);
}

That's all you need to do! For more details about usage, See This.
