ComfyUI Node: imageConcat

imageConcat:

The easy imageConcat node is designed to seamlessly merge two images into one, providing a straightforward way to create composite images. This node is particularly useful for AI artists who want to combine visual elements from different sources without needing advanced image editing skills. By specifying the direction of concatenation, you can control how the images are joined, whether side-by-side or top-to-bottom. Additionally, the node offers an option to match the sizes of the images before concatenation, ensuring a smooth and visually appealing result. This functionality is essential for creating cohesive and professional-looking composite images, making it a valuable tool in your image processing workflow.

imageConcat Input Parameters:

image1

This parameter represents the first image to be concatenated. It serves as one of the two primary visual inputs for the node. The image should be in a compatible format and will be combined with the second image based on the specified direction.

image2

This parameter represents the second image to be concatenated. Similar to image1, it is a primary visual input that will be merged with the first image. The node can adjust the size of this image to match image1 if the match_image_size option is enabled.

direction

This parameter determines the direction in which the images will be concatenated. The available options are right, down, left, and up. For example, choosing right will place image2 to the right of image1, while choosing down will place image2 below image1. The default value is right.

match_image_size

This boolean parameter specifies whether the node should resize image2 to match the dimensions of image1 before concatenation. If set to True, image2 will be resized to ensure a seamless merge. The default value is False.

imageConcat Output Parameters:

IMAGE

The output is a single concatenated image resulting from the combination of image1 and image2 based on the specified direction and size matching options. This composite image can be used for further processing or as a final output in your image creation workflow.

imageConcat Usage Tips:

• To create a horizontal composite image, set the direction parameter to right or left depending on the desired order of the images.
• For vertical concatenation, use the down or up options in the direction parameter to stack the images accordingly.
• Enable the match_image_size option to ensure that the images align perfectly, especially when they have different dimensions.

imageConcat Common Errors and Solutions:

Image size mismatch error

• Explanation: This error occurs when the images have different dimensions and the match_image_size option is not enabled.
• Solution: Enable the match_image_size option to automatically resize image2 to match the dimensions of image1.

Invalid direction value

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

Unsupported image format

• Explanation: This error occurs when the input images are in an unsupported format.
• Solution: Convert the images to a supported format such as PNG or JPEG before using the easy imageConcat node.
