ImageStitch - ComfyUI Built-in Node Documentation

Complete documentation for the ImageStitch node in ComfyUI. Learn its inputs, outputs, parameters and usage.

This node allows you to stitch two images together in a specified direction (up, down, left, right), with support for size matching and spacing between images.

Inputs

Parameter Name	Data Type	Input Type	Default	Range	Description

image2	IMAGE	Optional	None	-	The second image to be stitched, if not provided returns only the first image
direction	STRING	Required	right	right/down/left/up	The direction to stitch the second image: right, down, left, or up
match_image_size	BOOLEAN	Required	True	True/False	Whether to resize the second image to match the dimensions of the first image
spacing_width	INT	Required	0	0-1024	Width of spacing between images, must be an even number
spacing_color	STRING	Required	white	white/black/red/green/blue	Color of the spacing between stitched images

For spacing_color, when using colors other than “white/black”, if match_image_size is set to false, the padding area will be filled with black

Workflow Example

In the workflow below, we use 3 input images of different sizes as examples:

• image1: 500x300
• image2: 400x250
• image3: 300x300

First Image Stitch Node

• match_image_size: false, images will be stitched at their original sizes
• direction: up, image2 will be placed above image1
• spacing_width: 20
• spacing_color: black

Output image 1:

Second Image Stitch Node

• match_image_size: true, the second image will be scaled to match the height or width of the first image
• direction: right, image3 will appear on the right side
• spacing_width: 20
• spacing_color: white

Output image 2:
