ComfyUI Node: Image Muxer

Image Muxer:

The ImageMuxer node is designed to help you seamlessly switch between multiple images based on a specified input selector. This node is particularly useful when you have several images and need to dynamically choose one for further processing or display. By providing a simple yet effective way to select an image from a set, the ImageMuxer enhances your workflow efficiency and flexibility, allowing you to manage and manipulate images with ease.

Image Muxer Input Parameters:

image_1

This is the first image input. It is one of the required images that you can select from using the input selector. The image should be in a compatible format that the node can process.

image_2

This is the second image input. Similar to image_1, it is a required input and provides another option for selection through the input selector.

input_selector

The input selector is an integer parameter that determines which image to output. The default value is 0, which corresponds to the first image. The value can range from 0 to 3, depending on how many images you provide. For example, if you set the input selector to 1, the node will output image_2.

image_3

This is an optional third image input. If provided, it expands the selection options available through the input selector.

image_4

This is an optional fourth image input. Like image_3, it offers an additional image choice for the input selector to choose from.

Image Muxer Output Parameters:

IMAGE

The output is a single image selected from the provided inputs based on the input selector value. This output image can then be used for further processing or display in your workflow.

Image Muxer Usage Tips:

• To dynamically switch between images, use the input selector parameter effectively. For instance, if you have a sequence of images and want to display them one by one, you can increment the input selector value in a loop.
• When working with optional images (image_3 and image_4), ensure that the input selector value does not exceed the number of provided images to avoid errors.

Image Muxer Common Errors and Solutions:

IndexError: list index out of range

• Explanation: This error occurs when the input selector value is higher than the number of provided images.
• Solution: Ensure that the input selector value is within the range of the provided images. For example, if you only provide image_1 and image_2, the input selector should be either 0 or 1.

TypeError: 'NoneType' object is not subscriptable

• Explanation: This error happens when an optional image (image_3 or image_4) is not provided, but the input selector tries to access it.
• Solution: Make sure to provide all images that the input selector might access, or adjust the input selector value to only select from the provided images.
