ComfyUI Node: JoinImageBatch

JoinImageBatch:

The easy joinImageBatch node is designed to merge a batch of images into a single, larger image. This node is particularly useful when you want to create a composite image from multiple individual images, either by stacking them horizontally or vertically. This can be beneficial for creating image galleries, collages, or any scenario where you need to visualize multiple images together in a single frame. The node simplifies the process of combining images, ensuring that they are seamlessly joined according to the specified mode, making it an essential tool for AI artists looking to streamline their image processing workflows.

JoinImageBatch Input Parameters:

images

This parameter expects a batch of images that you want to combine into a single image. The images should be in the format of a tensor with dimensions representing the batch size, height, width, and channels. The node will process these images and merge them according to the specified mode.

mode

This parameter determines the direction in which the images will be joined. It accepts two options: "horizontal" and "vertical". If "horizontal" is selected, the images will be concatenated side by side. If "vertical" is selected, the images will be stacked on top of each other. The default value is "horizontal".

JoinImageBatch Output Parameters:

image

The output is a single image that results from joining the input batch of images according to the specified mode. This image will have dimensions that reflect the combined size of the input images, either in width (for horizontal mode) or height (for vertical mode).

JoinImageBatch Usage Tips:

• To create a horizontal collage, ensure that the mode parameter is set to "horizontal". This will align the images side by side.
• For a vertical stack of images, set the mode parameter to "vertical". This will place the images one on top of the other.
• Ensure that all images in the batch have the same dimensions to avoid unexpected results or errors during the joining process.

JoinImageBatch Common Errors and Solutions:

Images in the batch have different dimensions

• Explanation: The images in the batch do not have the same height and width, which is required for seamless joining.
• Solution: Resize or crop the images to ensure they all have the same dimensions before passing them to the node.

Invalid mode selected

• Explanation: The mode parameter has a value that is not recognized (neither "horizontal" nor "vertical").
• Solution: Ensure that the mode parameter is set to either "horizontal" or "vertical". Check for any typos or incorrect values.
