ComfyUI Node: Image Crop Square Location

Image Crop Square Location:

The Image Crop Square Location node is designed to crop a square region from an image based on specified coordinates and size. This node is particularly useful for focusing on a specific area of an image, ensuring that the cropped region is centered around the given coordinates. It automatically adjusts the cropping boundaries to fit within the image dimensions, providing a resized output that maintains the aspect ratio. This functionality is essential for tasks that require precise image manipulation, such as preparing images for machine learning models or creating visually appealing compositions.

Image Crop Square Location Input Parameters:

x

The x-coordinate of the center of the cropping region. This parameter determines the horizontal position of the crop's center. The value should be within the width of the image. The default value is 256.

y

The y-coordinate of the center of the cropping region. This parameter determines the vertical position of the crop's center. The value should be within the height of the image. The default value is 256.

size

The size of the square cropping region. This parameter defines the width and height of the square crop. The value should be a positive integer, and the default value is 512.

Image Crop Square Location Output Parameters:

cropped_image

The cropped and resized image. This output provides the image data after cropping the specified square region and resizing it to ensure the dimensions are multiples of 8. The output is in tensor format.

crop_data

A tuple containing the size of the cropped image and the coordinates of the cropping region. This output provides metadata about the crop, including the dimensions of the cropped area and the exact coordinates used for cropping.

Image Crop Square Location Usage Tips:

• Ensure that the x and y coordinates are within the dimensions of the image to avoid errors.
• Use the size parameter to control the area of interest; larger values will include more of the surrounding area.
• The node automatically adjusts the crop to fit within the image boundaries, so you don't need to worry about specifying coordinates that are too close to the edges.

Image Crop Square Location Common Errors and Solutions:

Invalid crop dimensions. Please check the values for top, left, right, and bottom.

• Explanation: This error occurs when the calculated crop dimensions result in a non-positive width or height.
• Solution: Ensure that the x and y coordinates are within the image dimensions and that the size parameter is a positive integer.

Image size is too small for the specified crop size.

• Explanation: This error occurs when the specified crop size is larger than the image dimensions.
• Solution: Reduce the size parameter to fit within the image dimensions or use a larger image.
