ComfyUI Node: Image List to Image Batch

Image List to Image Batch:

The ImageListToImageBatch node is designed to streamline the process of combining multiple images into a single batch. This is particularly useful when you have a list of individual images that you want to process together as a batch. The node ensures that all images in the list are compatible in terms of dimensions, automatically resizing them if necessary, and then concatenates them along the batch dimension. This functionality is essential for tasks that require batch processing, such as applying the same transformation or model inference to multiple images simultaneously. By using this node, you can efficiently manage and manipulate image data, saving time and effort in your workflow.

Image List to Image Batch Input Parameters:

images

The images parameter expects a list of images that you want to combine into a single batch. Each image in the list should be in the same format, but they can have different dimensions. The node will automatically resize images to match the dimensions of the first image in the list, ensuring compatibility. This parameter is crucial as it determines the input data that will be processed and combined. There are no specific minimum, maximum, or default values for this parameter, but it should contain at least one image to function correctly.

Image List to Image Batch Output Parameters:

IMAGE

The output parameter IMAGE is a single batch of images created by concatenating the input images along the batch dimension. This batch can then be used for further processing or analysis. The output is significant because it allows you to handle multiple images as a single entity, facilitating batch operations and improving efficiency in tasks that require processing multiple images simultaneously.

Image List to Image Batch Usage Tips:

• Ensure that all images in the input list are in the same format to avoid compatibility issues.
• Use this node when you need to apply the same transformation or model inference to multiple images, as it simplifies the process by combining them into a single batch.
• If your images have different dimensions, the node will automatically resize them to match the first image, but for best results, try to use images with similar dimensions.

Image List to Image Batch Common Errors and Solutions:

ValueError: Expected input images to have the same dimensions

• Explanation: This error occurs when the input images have different dimensions and the node is unable to resize them to match.
• Solution: Ensure that all input images have the same dimensions or are compatible for resizing. You can manually resize the images before inputting them into the node.

TypeError: Input images must be a list

• Explanation: This error occurs when the input is not provided as a list of images.
• Solution: Make sure to provide the input images as a list. For example, [image1, image2, image3].

RuntimeError: Concatenation failed due to incompatible image formats

• Explanation: This error occurs when the input images are in different formats that cannot be concatenated.
• Solution: Ensure that all input images are in the same format before passing them to the node. Convert the images to a common format if necessary.
