ComfyUI Node: Resize image to square

Resize image to square:

LF_ResizeImageToSquare is a node designed to resize images to a square format, ensuring that the output dimensions are equal in height and width. This node is particularly useful for standardizing image sizes, which is essential for various applications such as machine learning, web design, and digital art. By resizing images to a square, you can maintain consistency across your dataset or project, making it easier to manage and process images. The node offers flexibility in terms of resampling methods and crop positions, allowing you to customize the resizing process to suit your specific needs. Whether you are working with a single image or a batch of images, LF_ResizeImageToSquare simplifies the task of resizing while preserving the quality and integrity of the original images.

Resize image to square Input Parameters:

node_id

This parameter uniquely identifies the node instance within the workflow. It is used internally to track and manage the node's operations and is typically auto-generated by the system.

images

This parameter accepts a list of images or a single image that you want to resize. The images should be in a compatible format that the node can process. The function of this parameter is to provide the input images that will be resized to a square format.

square_size

This parameter specifies the size of the square to which the images will be resized. It determines both the height and width of the output images. The impact of this parameter is significant as it directly affects the dimensions of the resized images. The value should be a positive integer representing the number of pixels for each side of the square.

resample_method

This parameter defines the method used for resampling the images during the resizing process. Common options include "nearest", "bilinear", and "bicubic". The choice of resample method can affect the quality and smoothness of the resized images. For example, "nearest" is faster but may produce a more pixelated image, while "bicubic" provides smoother results but is computationally more intensive.

crop_position

This parameter determines the position from which the image will be cropped if the aspect ratio does not match the square size. Options typically include "center", "top-left", "top-right", "bottom-left", and "bottom-right". The crop position affects which part of the image is retained and which part is discarded during the resizing process.

Resize image to square Output Parameters:

resized_images

This parameter contains the list of images or a single image that has been resized to the specified square dimensions. The function of this output is to provide the resized images that are ready for further processing or use. The resized images maintain the quality and integrity of the original images while conforming to the specified square size.

Resize image to square Usage Tips:

• Ensure that the square_size parameter is set to a value that suits your project's requirements, balancing between image quality and processing time.
• Choose the resample_method based on the desired quality of the resized images; "bicubic" is recommended for high-quality results.
• Use the crop_position parameter to control which part of the image is most important to retain, especially when the original image's aspect ratio does not match the square size.

Resize image to square Common Errors and Solutions:

"Invalid image format"

• Explanation: The input images are not in a compatible format that the node can process.
• Solution: Ensure that the images are in a supported format such as JPEG, PNG, or TIFF before passing them to the node.

"Square size must be a positive integer"

• Explanation: The square_size parameter is set to a non-positive value.
• Solution: Set the square_size parameter to a positive integer representing the number of pixels for each side of the square.

"Unsupported resample method"

• Explanation: The resample_method parameter is set to an unsupported value.
• Solution: Choose a valid resample method such as "nearest", "bilinear", or "bicubic".

"Invalid crop position"

• Explanation: The crop_position parameter is set to an invalid value.
• Solution: Set the crop_position parameter to a valid option such as "center", "top-left", "top-right", "bottom-left", or "bottom-right".
