ComfyUI Node: ExtendImageList

ExtendImageList:

The ExtendImageList node is designed to help you efficiently manage and manipulate lists of images within your AI art projects. This node allows you to extend an existing list of images by appending additional images to it, making it easier to handle multiple images in a streamlined manner. By using this node, you can simplify the process of combining and organizing images, which is particularly useful when working with large batches or sequences of images. The primary goal of the ExtendImageList node is to enhance your workflow by providing a straightforward method to aggregate images into a single list, thereby reducing the complexity of managing multiple image inputs.

ExtendImageList Input Parameters:

inputs_len

This parameter specifies the number of input lists that you want to extend. It determines how many lists of images will be processed and combined into a single extended list. The value should be an integer representing the count of input lists. For example, if you have three separate lists of images that you want to merge, you would set inputs_len to 3. This parameter is crucial as it directly impacts the number of images that will be included in the final extended list.

kwargs

This parameter represents the keyword arguments that contain the actual lists of images to be extended. Each keyword argument corresponds to a specific list of images, and the node will iterate through these lists to create the extended list. The names of these keyword arguments are dynamically generated based on the type of input (in this case, images) and the index of the list. For instance, if you have three lists of images, the keyword arguments might be named image_0, image_1, and image_2. This parameter allows for flexible and dynamic input handling, ensuring that the node can accommodate various numbers of image lists.

ExtendImageList Output Parameters:

list

The output parameter list is the extended list of images that results from combining all the input lists specified by the inputs_len and kwargs parameters. This extended list contains all the images from the input lists, merged into a single, cohesive list. The output is particularly useful for subsequent nodes or processes that require a consolidated list of images, as it simplifies the handling and manipulation of multiple images by providing a unified list.

ExtendImageList Usage Tips:

• To effectively use the ExtendImageList node, ensure that you correctly specify the number of input lists using the inputs_len parameter. This will help the node accurately process and combine the images.
• When providing the keyword arguments (kwargs), make sure that each argument corresponds to a valid list of images. This will ensure that the node can successfully extend the lists without encountering errors.

ExtendImageList Common Errors and Solutions:

Mismatched input lengths

• Explanation: This error occurs when the number of input lists specified by inputs_len does not match the actual number of lists provided in the keyword arguments.
• Solution: Verify that the inputs_len parameter accurately reflects the number of image lists you are providing. Ensure that all keyword arguments are correctly named and correspond to valid lists of images.

Invalid keyword arguments

• Explanation: This error happens when the keyword arguments do not correspond to valid lists of images or are incorrectly named.
• Solution: Double-check the names and contents of the keyword arguments to ensure they are valid lists of images. Make sure the names follow the expected format based on the type of input and index.

Empty input lists

• Explanation: This error occurs when one or more of the input lists are empty, resulting in an incomplete extended list.
• Solution: Ensure that all input lists contain valid images before passing them to the node. If an input list is empty, consider removing it or providing a default list of images.
