ComfyUI Node: Image Concatenate Multi

Image Concatenate Multi:

The ImageConcatMulti node is designed to combine multiple images into a single image. This node allows you to specify the number of images to be concatenated and the direction in which they should be combined. It provides flexibility in handling image sizes, ensuring that images can be resized to match each other if needed. This node is particularly useful for creating composite images from multiple sources, enabling you to create complex visual compositions with ease. By specifying the direction of concatenation, you can control the layout of the final image, making it a versatile tool for various artistic and design purposes.

Image Concatenate Multi Input Parameters:

inputcount

inputcount determines the number of images to be concatenated. This parameter allows you to specify how many images you want to combine, with a minimum value of 2 and a maximum value of 1000. The default value is 2. Adjusting this parameter will dynamically update the node to accept the specified number of image inputs.

image_1

image_1 is the first image to be concatenated. This parameter accepts an image input and serves as the base image for the concatenation process.

image_2

image_2 is the second image to be concatenated. This parameter accepts an image input and will be combined with image_1 based on the specified direction.

direction

direction specifies the direction in which the images will be concatenated. The available options are right, down, left, and up, with the default value being right. This parameter controls the layout of the final composite image by determining the order in which the images are placed relative to each other.

match_image_size

match_image_size is a boolean parameter that determines whether the images should be resized to match each other's dimensions before concatenation. The default value is False. When set to True, the images will be resized to the dimensions of the first image, ensuring a seamless combination.

Image Concatenate Multi Output Parameters:

images

images is the output parameter that contains the final concatenated image. This parameter provides the resulting composite image created by combining the input images according to the specified direction and size matching settings. The output is a single image that integrates all the input images into one cohesive visual.

Image Concatenate Multi Usage Tips:

• To create a horizontal strip of images, set the direction parameter to right and ensure that inputcount matches the number of images you want to concatenate.
• If your images have different dimensions, enable the match_image_size parameter to ensure a smooth and aligned composite image.
• Experiment with different direction settings to achieve various layouts, such as vertical stacks (down) or reversed orders (left and up).

Image Concatenate Multi Common Errors and Solutions:

"KeyError: 'image_X'"

• Explanation: This error occurs when the specified number of images (inputcount) does not match the actual number of image inputs provided.
• Solution: Ensure that the inputcount parameter accurately reflects the number of image inputs you have connected to the node.

"RuntimeError: Sizes of tensors must match except in dimension 1"

• Explanation: This error happens when the images have different dimensions and match_image_size is set to False.
• Solution: Set the match_image_size parameter to True to resize the images to the same dimensions before concatenation.

"ValueError: Invalid direction specified"

• Explanation: This error occurs if an invalid value is provided for the direction parameter.
• Solution: Ensure that the direction parameter is set to one of the valid options: right, down, left, or up.
