ComfyUI Node: 🖼🖼 Merge Images/Videos 📹📹 (Vertically)

🖼🖼 Merge Images/Videos 📹📹 (Vertically):

The Bjornulf_MergeImagesVertically node is designed to seamlessly combine multiple images into a single, vertically aligned image. This node is particularly useful for AI artists who want to create composite images by stacking them one on top of the other. By leveraging the power of PyTorch and NumPy, this node efficiently handles image data, ensuring that the final output maintains the quality and integrity of the original images. The primary goal of this node is to provide a straightforward and efficient method for merging up to four images vertically, making it an essential tool for creating complex visual compositions without the need for extensive manual editing.

🖼🖼 Merge Images/Videos 📹📹 (Vertically) Input Parameters:

image1

image1 is the first required input image that will be used as the base for the vertical merging process. This parameter is crucial as it sets the initial dimensions and color channels for the combined image. There are no specific minimum or maximum values for this parameter, but it should be a valid image tensor with appropriate dimensions.

image2

image2 is the second required input image that will be stacked vertically below image1. This parameter is essential for creating the vertical composite, and like image1, it should be a valid image tensor. The dimensions of image2 will influence the overall height of the final merged image.

image3

image3 is an optional input parameter that allows you to add a third image to the vertical stack. If provided, this image will be placed below image2. This parameter offers flexibility in creating more complex compositions by adding additional layers to the merged image.

image4

image4 is another optional input parameter that enables you to include a fourth image in the vertical stack. If used, this image will be positioned below image3, further extending the height of the final composite image. This parameter is useful for artists looking to create even more intricate vertical compositions.

🖼🖼 Merge Images/Videos 📹📹 (Vertically) Output Parameters:

IMAGE

The output parameter IMAGE represents the final vertically merged image. This output is a single image tensor that combines all the input images into one cohesive visual. The importance of this output lies in its ability to maintain the quality and color integrity of the original images while presenting them in a unified vertical format. This output can be used for further processing or as a final artwork.

🖼🖼 Merge Images/Videos 📹📹 (Vertically) Usage Tips:

• Ensure that all input images have the same number of color channels to avoid unexpected results in the merged image.
• Use images with similar widths to maintain a consistent and visually appealing vertical alignment in the final output.

🖼🖼 Merge Images/Videos 📹📹 (Vertically) Common Errors and Solutions:

Mismatched Image Dimensions

• Explanation: This error occurs when the input images have different numbers of color channels or incompatible dimensions.
• Solution: Verify that all input images have the same number of color channels and similar widths before merging.

Invalid Image Tensor

• Explanation: This error arises when one or more input parameters are not valid image tensors.
• Solution: Ensure that all input images are correctly formatted as image tensors with appropriate dimensions and data types.
