# BurstLinker
[  ](https://bintray.com/succlz123/maven/burst-linker/_latestVersion)
Idea from: [square/gifencoder](https://github.com/square/gifencoder)
BurstLinker is a simple C++ GIF encode library.
## Download
### Android
Gradle:
```
implementation 'com.bilibili:burst-linker:latest-version'
```
#### Build Environment
Android Studio 3.4.1
NDK r20
#### Basic usage
``` java
int delayMs = 1000;
String filePath = getCacheDir() + File.separator + "out.gif";
BurstLinker burstLinker = new BurstLinker();
try {
burstLinker.init(width, height, filePath);
Bitmap colorBitmap = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(colorBitmap);
Paint p = new Paint();
int[] colors = new int[]{0xFFF00000, 0xFFFFFF00, 0xFFFFFFFF};
for (int color : colors) {
p.setColor(color);
canvas.drawRect(0, 0, width, height, p);
burstLinker.connect(colorBitmap, BurstLinker.OCTREE_QUANTIZER,
BurstLinker.NO_DITHER, 0, 0, delayMs);
}
} catch (GifEncodeException e) {
e.printStackTrace();
} finally {
burstLinker.release();
}
```
#### Enable RenderScript Support
> This is an untested feature.
1. Choose the Git branch "/feature/render-script".
2. Sync Project with Gradle Files, It will generate the required file named "ScriptC_*.cpp".
3. Uncomment the line 64 of the "/lib/CMakeLists.txt".
4. Try this function.
### Linux & Mac
1. Install [CMake](http://www.cmake.org/)
- Mac `brew install cmake`
- ArchLinux `sudo pacman -S cmake`
2. Build
- `cd /BurstLinker`
- `mkdir cmake-build-debug; cd cmake-build-debug`
- `cmake ..`
- `make BurstLinker`
3. Run
- `./BurstLinker 1000 1.jpg 2.jpg 3.jpg`
- See the "out.gif"
### Windows
1. Install [Microsoft Visual Studio](https://www.visualstudio.com/) & [CMake](http://www.cmake.org/)
2. Build
- `cd /BurstLinker`
- `mkdir cmake-build-debug; cd cmake-build-debug`
- `cmake ..`
- Open the "BurstLinker.sln"
- Solution Explorer -> BurstLinker -> Build
3. Run
- `cd Debug`
- `BurstLinker.exe 1000 1.jpg 2.jpg 3.jpg`
- See the "out.gif"
## Samples
### Different quantizers & ditherers
- Original
- Uniform + No
- MedianCut + No
- KMeans + No
- Random + No
- Octree + No
- NeuQuant - 10 + No
- NeuQuant - 1 + No
- Octree + M2
- Octree + Bayer
- Octree + FloydSteinberg
### Encodes images with transparent channels
- Original
- Octree + No + Default
Display all Alpha channels greater than 0. (ARGB.a != 0)
- Octree + No + Ignored translucency
Display only the Alpha channels equal to 255. (ARGB.a == 255)
