HokoBlur is an Android component which provides dynamic blur effect.

1. Introductions

Functions：
- Add blur to the image；
- Dynamic blur, real-time blurring of the background。
Features：
- Multiple schemes: RenderScript、OpenGL、Native and Java；
- Multiple algorithms: Box、Stack and Gaussian algorithms. Provide different blur effect；
- Multi-core and multi-threading, accelerate blurring，asynchronous interface；
- ?iOS-like dynamic backgroud blur: Compared to using RenderScript to process bitmaps, the component has better performance and effect.

Static Blur

synchronous api

HokoBlur.with(context)    .scheme(Blur.SCHEME_NATIVE) //different implementation, RenderScript、OpenGL、Native(default) and Java    .mode(Blur.MODE_STACK) //blur algorithms，Gaussian、Stack(default) and Box    .radius(10) //blur radius，max=25，default=5    .sampleFactor(2.0f) //scale factor，if factor=2，the width and height of a bitmap will be scale to 1/2 sizes，default=5    .forceCopy(false) //If scale factor=1.0f，the origin bitmap will be modified. You could set forceCopy=true to avoid it. default=false    .needUpscale(true) //After blurring，the bitmap will be upscaled to origin sizes，default=true    .translateX(150)//add x axis offset when blurring    .translateY(150)//add y axis offset when blurring    .processor() //build a blur processor    .blur(bitmap);    //blur a bitmap, synchronous method

Daily development does not need such complicated settings. If you want a blur effect, just use as follow:

Bitmap outBitmap = Blur.with(context).blur(bitmap);

When it comes to a large size bitmap, it is recommended to use an asynchronous method. The blur job could be cancelled.

Future f = HokoBlur.with(this)    .scheme(Blur.SCHEME_NATIVE)    .mode(Blur.MODE_STACK)    .radius(10)    .sampleFactor(2.0f)    .forceCopy(false)    .needUpscale(true)    .asyncBlur(bitmap, new AsyncBlurTask.CallBack() {        @Override        public void onBlurSuccess(Bitmap outBitmap) {            // do something...        }        @Override        public void onBlurFailed() {        }    });f.cancel(false);
