ComfyUI Node: Scale Down To Size

Scale Down To Size:

The ImageScaleDownToSize node is designed to resize images to a specified dimension while maintaining the aspect ratio. This node is particularly useful for AI artists who need to standardize image sizes for consistency in their projects. By scaling down images to a target size, it ensures that the images fit within the desired dimensions without distortion. The node offers flexibility by allowing you to choose whether the scaling is based on the maximum or minimum dimension of the image, providing control over how the image is resized. This functionality is essential for preparing images for further processing or for creating uniform image sets.

Scale Down To Size Input Parameters:

images

This parameter accepts the images that you want to scale down. The images should be in a format that the node can process, typically tensors representing the image data.

size

This integer parameter specifies the target size for the image scaling. The default value is 512, with a minimum value of 1 and a maximum value defined by MAX_RESOLUTION. This size determines the dimension to which the image will be scaled down, either based on the maximum or minimum dimension of the original image, depending on the mode selected.

mode

This boolean parameter allows you to choose the scaling mode. When set to True (labelled as "max"), the image is scaled down based on its maximum dimension. When set to False (labelled as "min"), the image is scaled down based on its minimum dimension. The default value is True.

Scale Down To Size Output Parameters:

IMAGE

The output is the scaled-down image. This image retains the aspect ratio of the original but fits within the specified size constraints. The output format is consistent with the input format, typically a tensor representing the image data.

Scale Down To Size Usage Tips:

• To maintain the highest quality, ensure that the size parameter is set appropriately for your project's needs. For example, if you are preparing images for a web gallery, a size of 512 might be suitable.
• Use the mode parameter to control how the image is scaled. If you want to ensure that the longest side of the image fits within the specified size, set mode to True. If you want the shortest side to fit, set mode to False.
• Combine this node with other image processing nodes to create a streamlined workflow for preparing images for various applications.

Scale Down To Size Common Errors and Solutions:

"Invalid image format"

• Explanation: The input images are not in a format that the node can process.
• Solution: Ensure that the images are provided in a compatible format, typically as tensors representing the image data.

"Size parameter out of range"

• Explanation: The size parameter is set to a value outside the allowed range.
• Solution: Adjust the size parameter to be within the range of 1 to MAX_RESOLUTION.

"Mode parameter invalid"

• Explanation: The mode parameter is not set to a valid boolean value.
• Solution: Ensure that the mode parameter is set to either True or False.

"Image scaling failed"

• Explanation: An error occurred during the image scaling process.
• Solution: Check the input images and parameters for any inconsistencies or errors, and try again. If the problem persists, consider checking the node's implementation for potential issues.
