Introductions 11 | 12 | - Functions： 13 | 14 | - Add blur to the image； 15 | - **Dynamic blur, real-time blurring of the background**。 16 | 17 | - Features： 18 | - Multiple schemes: RenderScript、OpenGL、Native and Java； 19 | - Multiple algorithms: Box、Stack and Gaussian algorithms. Provide different blur effect； 20 | - Multi-core and multi-threading, accelerate blurring，asynchronous interface； 21 | 22 | ### 2. Getting started 23 | 24 | 25 | #### Download 26 | 27 | ```groovy 28 | implementation 'io.github.hokofly:hoko-blur:1.5.3' 29 | ``` 30 | 31 | #### Static Blur 32 | 33 | synchronous api 34 | 35 | ```java 36 | HokoBlur.with(context) 37 | .scheme(Blur.SCHEME_NATIVE) //different implementation, RenderScript、OpenGL、Native(default) and Java 38 | .mode(Blur.MODE_STACK) //blur algorithms，Gaussian、Stack(default) and Box 39 | .radius(10) //blur radius，max=25，default=5 40 | .sampleFactor(2.0f) //scale factor，if factor=2，the width and height of a bitmap will be scale to 1/2 sizes，default=5 41 | .forceCopy(false) //If scale factor=1.0f，the origin bitmap will be modified. You could set forceCopy=true to avoid it. default=false 42 | .translateX(150)//add x axis offset when blurring 43 | .translateY(150)//add y axis offset when blurring 44 | .processor() //build a blur processor 45 | .blur(bitmap); //blur a bitmap, synchronous method 46 | 47 | ``` 48 | 49 | Daily development does not need such complicated settings. If you want a blur effect, just use as follow: 50 | 51 | ```java 52 | Bitmap outBitmap = Blur.with(context).blur(bitmap); 53 | 54 | ``` 55 | 56 | When it comes to a large size bitmap, it is recommended to use an asynchronous method. The blur job could be cancelled. 57 | 58 | 59 | ```java 60 | Future f = HokoBlur.with(this) 61 | .scheme(Blur.SCHEME_NATIVE) 62 | .mode(Blur.MODE_STACK) 63 | .radius(10) 64 | .sampleFactor(2.0f) 65 | .forceCopy(false) 66 | .asyncBlur(bitmap, new AsyncBlurTask.CallBack() { 67 | @Override 68 | public void onBlurSuccess(Bitmap outBitmap) { 69 | // do something... 70 | } 71 | 72 | @Override 73 | public void onBlurFailed() { 74 | 75 | } 76 | }); 77 | f.cancel(false); 78 | 79 | ``` 80 | 81 | ### 3. Sample 82 | 83 | #### Animation 84 | 85 | ![](https://github.com/HokoFly/HokoBlur/blob/master/doc/graphic/animation_blur_progress.gif?raw=true) 86 | 87 | 88 | #### Arbitrary Locaton Blur 89 | 90 | ![](https://github.com/HokoFly/HokoBlur/blob/master/doc/graphic/dynamic_blur.gif?raw=true) 91 | 92 | 93 | 94 | ### 4. Dynamic background blur 95 | 96 | Dynamic Blur provides real-time background blurring of View and ViewGroup, not based on Bitmap implementations. The component will blur the area where the View is located. See the repository [HokoBlurDrawable](https://github.com/HokoFly/HokoBlurDrawable). 97 | 98 | 99 | 100 | ### 5. Tips 101 | 102 | 103 | 1. When the Bitmap is not scaled (```sampleFactor(1.0f)```), the incoming Bitmap will be directly modified by the subsequent operations. So when the function returns a bitmap, it can be used immediately. 104 | 105 | 2. **It is strongly recommended to use the downScale operation before the blur operation to reduce the size of the blurred image, which will greatly improve the blur efficiency and effect.** 106 | 107 | 3. Please limit the blur radius to 25. Increasing the radius leads to much less blur effect increase than by increasing the scale factor, and if the radius increase, blur efficiency will also decrease; 108 | 109 | 4. The RenderScript solution has to be verified for compatibility. If there are scenarios that require more computation and more complex blurring, the RenderScript scheme may be better. 110 | 111 | 5. Algorithm selection 112 | - If you have low effect requirements for blurring and want to blur the image faster, please choose Box algorithm.； 113 | - If you have a higher effect requirement for blurring and can tolerate slower blurring of the image, please choose the Gaussian algorithm; 114 | - The Stack algorithm has a blur effect that is very close to the Gaussian algorithm, and it improves the efficiency. Generally, the Stack algorithm is recommended; 115 | 116 | 6. BlurDrawable is implemented by OpenGL, so if the hardware acceleration is not enabled, the background blur will be invalid. 117 | 118 | 7. Sample and usage.
