ComfyUI Node: SendImageOnWebSocket

SendImageOnWebSocket:

The SendImageOnWebSocket node is designed to facilitate the real-time transmission of images over a WebSocket connection. This node is particularly useful in scenarios where you need to send image data directly to a client application without saving it to disk, enabling seamless and efficient image streaming. By leveraging the WebSocket protocol, this node ensures low-latency communication, making it ideal for applications that require immediate image updates, such as live previews or interactive AI art tools. The node processes image tensors, converts them into a suitable format, and sends them to a specified event, allowing for flexible integration into various workflows. Its primary function is to enhance the interactivity and responsiveness of applications by providing a direct channel for image data transmission.

SendImageOnWebSocket Input Parameters:

event

The event parameter is a string that specifies the event type or name associated with the image transmission. It acts as an identifier for the WebSocket message, allowing the receiving end to handle the image data appropriately based on the event context. This parameter does not have predefined minimum, maximum, or default values, as it is determined by the specific application or use case. The choice of event name should align with the expected handling logic on the client side to ensure correct processing of the received images.

images

The images parameter accepts a collection of image tensors that are to be sent over the WebSocket. These tensors represent the image data in a format that can be processed and converted into a standard image format, such as PNG, before transmission. The parameter does not have explicit minimum or maximum values, but the size and number of images can impact the performance and bandwidth usage of the WebSocket connection. It is important to ensure that the image tensors are correctly formatted and compatible with the node's processing capabilities to avoid errors during transmission.

SendImageOnWebSocket Output Parameters:

None

The SendImageOnWebSocket node does not produce any output parameters. Its primary function is to send images over a WebSocket connection, and it does not return any data or results upon completion. The absence of output parameters indicates that the node's operation is focused solely on the transmission process, with any necessary feedback or confirmation of successful transmission being handled by the receiving end of the WebSocket connection.

SendImageOnWebSocket Usage Tips:

• Ensure that the event parameter is correctly set to match the expected event name on the client side to facilitate proper handling of the received images.
• Optimize the size and number of images being sent to balance performance and bandwidth usage, especially in scenarios with limited network resources.

SendImageOnWebSocket Common Errors and Solutions:

Image tensor conversion error

• Explanation: This error occurs when the image tensors cannot be converted into a valid image format for transmission.
• Solution: Verify that the image tensors are correctly formatted and compatible with the node's processing requirements. Ensure that the tensors are not corrupted or malformed.

WebSocket connection failure

• Explanation: This error indicates that the WebSocket connection could not be established or was interrupted during transmission.
• Solution: Check the network connection and ensure that the WebSocket server is running and accessible. Verify that the server address and port are correctly configured.
