Provides nodes and API geared towards using ComfyUI as a backend for external tools.
ComfyUI exchanges images via the filesystem. This requires a multi-step process (upload images, prompt, download images), is rather inefficient, and invites a whole class of potential issues. It's also unclear at which point those images will get cleaned up if ComfyUI is used via external tools.
Sends an output image over the client WebSocket connection as PNG binary data.
- Inputs: the image (RGB or RGBA)
This will first send one binary message for each image in the batch via WebSocket:
12<PNG-data>
That is two 32-bit integers (big endian) with values 1 and 2 followed by the PNG binary data. There is also a JSON message afterwards:
{'type': 'executed', 'data': {'node': '<node ID>', 'output': {'images': [{'source': 'websocket', 'content-type': 'image/png', 'type': 'output'}, ...]}, 'prompt_id': '<prompt ID>}}
Download the repository and unpack into the custom_nodes folder in the ComfyUI installation directory.
Or clone via GIT, starting from ComfyUI installation directory:
cd custom_nodes
git clone https://github.com/Acly/comfyui-tooling-nodes.git
Restart ComfyUI and the nodes are functional.
