BurstLinker：跨平台 C++ GIF 编码库

BurstLinker

Idea from:square/gifencoder

BurstLinker is a simple C++ GIF encode library. You can easily use it on Android, Windows, Linux or other platforms.

Android platform
Download

Gradle:

implementation 'com.bilibili:burst-linker:latest-version'
Build Environment

Android Studio 3.0.1

NDK r16

Basic usage
int delayMs = 1000;
String filePath = getExternalCacheDir() + 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 experimental feature
Git branch/feature/render-script
Gradle sync, It will generate the required ScriptC.cpp
Uncomment the line 64 of the /lib/CMakeLists.txt
