🚀 A simple GIF encoder for Android.
Idea from: square/gifencoder
BurstLinker is a simple C++ GIF encode library.
Gradle:
implementation 'com.bilibili:burst-linker:latest-version'
Android Studio 3.4.1
NDK r20
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();
}
This is an untested feature.
