sandbox-gif
GitHub在沙箱环境中将 RGBA 帧序列编码为动画 GIF。通过 gifenc 模块处理量化和调色板，生成字节数组供后续写入。
Trigger Scenarios
需要将多帧图像数据合成为动态 GIF

GIF encoding in the sandbox
Specifier: @nodetool-ai/sandbox-gif. One module, gifenc. Import it at the top of the body.
Frames to a GIF
import { GIFEncoder, quantize, applyPalette } from "@nodetool-ai/sandbox-gif";
const gif = GIFEncoder();
for (const frame of inputs.frames) {
const palette = quantize(frame.rgba, 256);
const index = applyPalette(frame.rgba, palette);
gif.writeFrame(index, inputs.width, inputs.height, {
palette,
delay: frame.delay ?? 100
});
}
gif.finish();
return { bytes: gif.bytes() };
Each frame.rgba is a Uint8Array of length width * height * 4.
delay is milliseconds.
Gotchas
- You supply RGBA. Decode a still with
image.bytes/ canvas, then pack frames yourself. gif.bytes()is aUint8Array. Write it withworkspace.writeBytes.
