14 | ## What Is BlurKit?
15 | BlurKit is an extraordinarily easy to use and performant utility to render real time blur effects in Android.
16 |
17 |
18 |
19 |
20 |
21 | ## Perfomance
22 |
23 | BlurKit is faster than other blurring libraries due to a number of bitmap retrieval and drawing optimizations. We've been logging benchmarks for the basic high-intensity tasks for a 300dp x 100dp BlurView:
24 |
25 | | Task | BlurKit time | Avg. time without BlurKit |
26 | | --------------------------| -------------------| ----------------------- |
27 | | Retrieve source bitmap | 1-2 ms | 8-25 ms |
28 | | Blur and draw to BlurView | 1-2 ms | 10-50ms |
29 |
30 | This results in an average work/frame time of 2-4ms, which will be a seamless experience for most users and apps.
31 |
32 | ## Setup
33 | Add __BlurKit__ to the dependencies block of the app level `build.gradle`:
34 | ```groovy
35 | dependencies {
36 | implementation 'io.alterac.blurkit:blurkit:1.1.0'
37 | }
38 | ```
39 |
40 | ## Usage
41 | ### BlurLayout
42 | Add a `BlurLayout` to your XML layout just like any other view.
43 |
44 | ```xml
45 |
49 | ```
50 | In the `Main_Activity.java` you need to override the `onStart()` and `onStop()` methods to include the `BlurLayout` functionality.
51 | ```java
52 | BlurLayout blurLayout;
53 |
54 | @Override
55 | protected void onCreate(Bundle savedInstanceState) {
56 | super.onCreate(savedInstanceState);
57 | setContentView(R.layout.activity_main);
58 | blurLayout = findViewById(R.id.blurLayout);
59 | }
60 |
61 | @Override
62 | protected void onStart() {
63 | super.onStart();
64 | blurLayout.startBlur();
65 | }
66 |
67 | @Override
68 | protected void onStop() {
69 | blurLayout.pauseBlur();
70 | super.onStop();
71 | }
72 | ```
73 |
74 | The layout background will continuously blur the content behind it. If you know your background content will be somewhat static, you can set the layout `fps` to `0`. At any time you can re-blur the background content by calling `invalidate()` on the `BlurLayout`.
75 |
76 | ```xml
77 |
82 | ```
83 |
84 | Other attributes you can configure are the blur radius and the downscale factor. Getting these to work together well can take some experimentation. The downscale factor is a performance optimization; the bitmap for the background content will be downsized by this factor before being drawn and blurred.
85 |
86 | ```xml
87 |
94 | ```
95 |
96 | ### Creating BlurKit Outside Of A Layout
97 | You can use the `BlurKit` class which has a few useful blurring utilities. Before using this class outside of a `BlurLayout`, you need to initialize `BlurKit`.
98 |
99 | ```java
100 | public class MyApplication extends Application {
101 | @Override
102 | public void onCreate() {
103 | BlurKit.init(this);
104 | }
105 | }
106 | ```
107 |
108 | You can blur a `View`, or a `Bitmap` directly.
109 |
110 | ```java
111 | // View
112 | BlurKit.getInstance().blur(View src, int radius);
113 |
114 | // Bitmap
115 | BlurKit.getInstance().blur(Bitmap src, int radius);
116 | ```
117 |
118 | You can also __fastBlur__ a `View`. This optimizes the view blurring process by allocating a downsized bitmap and using a `Matrix` with the bitmaps `Canvas` to prescale the drawing of the view to the bitmap.
119 |
120 | ```java
121 | BlurKit.getInstance().fastBlur(View src, int radius, float downscaleFactor);
122 | ```
123 |
124 |
125 |
126 | ## Upcoming Features
127 | - [ ] `SurfaceView` support
128 | - [ ] Support for use outside of an `Activity` (dialogs, etc.)
129 | - [ ] Enhance retrieval of background content to only include views drawn behind the `BlurLayout`.
