Idea from: square/gifencoder

BurstLinker is a simple C++ GIF encode library.

Android platform

Download

Gradle:

ementation 'com.bilibili:burst-linker:latest-version'

Build Environment

Android Studio 3.0.1

NDK r16

Basic usage

delayMs = 1000;
ng filePath = getCacheDir() + File.separator + "out.gif";
tLinker burstLinker = new BurstLinker();

{
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);
}
tch (GifEncodeException e) {
e.printStackTrace();
nally {
burstLinker.release();

Enable RenderScript Support

This is an untested experimental feature

1. Git branch /feature/render-script
2. Gradle sync, It will generate the required ScriptC_*.cpp
3. Uncomment the line 64 of the /lib/CMakeLists.txt
4. Run

Unix-like platform

1. Install CMake

2. Mac brew install cmake
   

3. ArchLinux sudo pacman -S cmake

4. Build

5. cd /BurstLinker

6. mkdir cmake-build-debug; cd cmake-build-debug

7. cmake ..

8. make BurstLinker

9. Run

10. ./BurstLinker 1000 1.jpg 2.jpg 3.jpg

11. See out.gif

Windows platform

1. Install Microsoft Visual Studio & CMake

2. Build

3. cd /BurstLinker

4. mkdir cmake-build-debug; cd cmake-build-debug

5. cmake ..

6. Open BurstLinker.sln

7. Solution Explorer -> BurstLinker -> Build

8. Run
