ComfyUI Node: 🔶 Preview Stacking

🔶 Preview Stacking:

The chaosaiart_forPreview node is designed to facilitate the previewing of image batches in AI art generation workflows. This node is particularly useful for artists who need to visualize and stack multiple images during the creative process. By managing and stacking image batches, it helps in maintaining consistency and coherence across multiple frames or iterations. The node automatically handles the dimensions of the images and ensures that the preview does not exceed a specified maximum count, making it easier to manage large sets of images. This functionality is essential for animation and iterative design processes, where visual consistency and batch management are crucial.

🔶 Preview Stacking Input Parameters:

restart

This parameter is used to control whether the image batch should be restarted. When set to a value greater than or equal to 1, the node will reset the image batch, starting a new stack. This is useful when you want to begin a new sequence of images without carrying over the previous batch.

image

This parameter represents the input image that will be added to the batch. Each time the node is executed, the provided image is either added to the existing batch or starts a new batch based on the restart parameter. The image should be in a compatible format that the node can process.

Preview_Max

This integer parameter sets the maximum number of images that can be stacked in the preview batch. The default value is 50, with a minimum of 0 and a maximum of 10000. This parameter helps in controlling the size of the image batch, ensuring that it does not grow indefinitely and remains manageable.

🔶 Preview Stacking Output Parameters:

IMAGE

The output parameter IMAGE represents the stacked image batch. Depending on the input parameters and the current state of the node, this can either be a single image or a concatenated batch of images. This output is crucial for visualizing the combined result of multiple images, aiding in the iterative design and animation processes.

🔶 Preview Stacking Usage Tips:

• To start a new image batch, set the restart parameter to 1. This will reset the current batch and begin stacking from the new image.
• Adjust the Preview_Max parameter according to the number of images you expect to handle. Setting an appropriate maximum value helps in managing memory usage and ensures smoother performance.
• Use consistent image dimensions to avoid issues with stacking. The node checks for width and height consistency, so ensure that all input images have the same dimensions.

🔶 Preview Stacking Common Errors and Solutions:

Image dimensions mismatch

• Explanation: The input image dimensions do not match the dimensions of the existing batch.
• Solution: Ensure that all input images have the same width and height before adding them to the batch.

Exceeded Preview_Max limit

• Explanation: The number of images in the batch has exceeded the Preview_Max limit.
• Solution: Increase the Preview_Max value if you need to handle more images, or reset the batch by setting the restart parameter to 1.

Image batch is None

• Explanation: The image batch is not initialized or has been reset.
• Solution: Ensure that the first image added to the batch initializes the batch correctly. If necessary, set the restart parameter to 1 to reinitialize the batch.
