# ComfyUI Nodes for External Tooling Modified for GIMP * Provides nodes geared towards using GIMP as a frontend for ComfyUI. Modified from https://github.com/Acly/comfyui-tooling-nodes, thank you Acly. * What changed: Load Image, Load Mask, and Send Image were modified to send, receive, and process base64 encoded RGBA data rather than base64 encoded PNG data. * Sending and receiving images * Installation ## Sending and receiving images ### Load Image (GIMP) Loads an image from an RGBA image embedded into the prompt as base64 string. * Inputs: base64 encoded binary data of an RGBA image * Outputs: image (RGB) and mask (alpha) if present ### Load Mask (GIMP) Loads a mask (single channel) from an RGBA image embedded into the prompt as base64 string. * Inputs: base64 encoded binary data of an RGBA image * Outputs: the first channel of the image as mask ### Send Image GIMP (WebSocket) Sends an output image over the client WebSocket connection as RGBA data. * Inputs: the image (RGB or RGBA) This will send one base64 encoded message for the image via WebSocket: ``` 12 ``` That is one 32-bit integer (big endian) with value 12 followed by the base64 encoded RGBA binary data. There is also a JSON message afterwards: ``` {'type': 'executed', 'data': {'node': '', 'output': {'images': [{'source': 'websocket', 'content-type': 'image/png', 'type': 'output'}, ...]}, 'prompt_id': '}} ``` You can see how the data is received in the GIMP plugin at https://github.com/nchenevey1/gimp-comfy-tools ### Send Image with Dimensions GIMP (WebSocket) Sends an output image over the client WebSocket connection as RGBA data. * Inputs: the image (RGB or RGBA) This will send one base64 encoded message for the image via WebSocket: ``` 14

``` That is one 32-bit integer (big endian) with value 14 followed by the base64 encoded Width (32 bit), Height (32 bit), and RGBA binary data. There is also a JSON message afterwards: ``` {'type': 'executed', 'data': {'node': '', 'output': {'images': [{'source': 'websocket', 'content-type': 'image/png', 'type': 'output'}, ...]}, 'prompt_id': '}} ``` You can see how the data is received in the GIMP plugin at https://github.com/nchenevey1/gimp-comfy-tools ## Installation 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/nchenevey1/comfyui-gimp-nodes.git ``` Restart ComfyUI and the nodes are functional.
