(中文版本请参看这里)

HokoBlur is an Android component which provides dynamic blur effect.

1. Introductions

• Functions&＃xff1a;

  • Add blur to the image&＃xff1b;
  • Dynamic blur, real-time blurring of the background。

• Features&＃xff1a;

  • Multiple schemes: RenderScript、OpenGL、Native and Java&＃xff1b;
  • Multiple algorithms: Box、Stack and Gaussian algorithms. Provide different blur effect&＃xff1b;
  • Multi-core and multi-threading, accelerate blurring&＃xff0c;asynchronous interface&＃xff1b;
  • ?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&＃xff0c;Gaussian、Stack(default) and Box.radius(10) //blur radius&＃xff0c;max&＃61;25&＃xff0c;default&＃61;5.sampleFactor(2.0f) //scale factor&＃xff0c;if factor&＃61;2&＃xff0c;the width and height of a bitmap will be scale to 1/2 sizes&＃xff0c;default&＃61;5.forceCopy(false) //If scale factor&＃61;1.0f&＃xff0c;the origin bitmap will be modified. You could set forceCopy&＃61;true to avoid it. default&＃61;false.needUpscale(true) //After blurring&＃xff0c;the bitmap will be upscaled to origin sizes&＃xff0c;default&＃61;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 &＃61; 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 &＃61; 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() {&＃64;Overridepublic void onBlurSuccess(Bitmap outBitmap) {// do something...}&＃64;Overridepublic void onBlurFailed() {}});
f.cancel(false);
