ComfyUI Node: 🔧 Image Crop

🔧 Image Crop+:

ImageCrop+ is a powerful node designed to crop a specified region from an image, allowing you to focus on a particular area of interest. This node is particularly useful for tasks that require isolating a specific part of an image, such as preparing images for further processing, creating thumbnails, or simply removing unwanted sections. By providing precise control over the dimensions and position of the crop area, ImageCrop+ ensures that you can extract exactly the portion of the image you need. This node is essential for any workflow that involves image manipulation and transformation, offering a straightforward yet highly effective method to tailor images to your specific requirements.

🔧 Image Crop+ Input Parameters:

image

This parameter represents the input image that you want to crop. The image should be in a compatible format that the node can process.

width

This parameter defines the width of the crop area. It determines how many pixels wide the cropped section will be. The minimum value is 1, the maximum value is determined by the maximum resolution of the image, and the default value is 512. Adjusting this value allows you to control the horizontal size of the cropped area.

height

This parameter specifies the height of the crop area. It determines how many pixels tall the cropped section will be. The minimum value is 1, the maximum value is determined by the maximum resolution of the image, and the default value is 512. Adjusting this value allows you to control the vertical size of the cropped area.

x

This parameter sets the x-coordinate of the top-left corner of the crop area. It determines the horizontal starting point of the crop within the image. The minimum value is 0, the maximum value is determined by the maximum resolution of the image, and the default value is 0. Adjusting this value allows you to shift the crop area horizontally.

y

This parameter sets the y-coordinate of the top-left corner of the crop area. It determines the vertical starting point of the crop within the image. The minimum value is 0, the maximum value is determined by the maximum resolution of the image, and the default value is 0. Adjusting this value allows you to shift the crop area vertically.

🔧 Image Crop+ Output Parameters:

IMAGE

This output parameter represents the cropped image. The resulting image will be the section of the original image defined by the width, height, x, and y input parameters. This cropped image can then be used for further processing or analysis.

🔧 Image Crop+ Usage Tips:

• To focus on a specific area of an image, adjust the x and y parameters to set the starting point of the crop, and then fine-tune the width and height to capture the desired section.
• Use the default values for width and height if you want to quickly crop a standard-sized section from the top-left corner of the image.
• Ensure that the x and y coordinates, along with the width and height, do not exceed the dimensions of the original image to avoid errors.

🔧 Image Crop+ Common Errors and Solutions:

"IndexError: index out of bounds"

• Explanation: This error occurs when the specified crop area exceeds the dimensions of the original image.
• Solution: Ensure that the x and y coordinates, combined with the width and height, do not extend beyond the edges of the image. Adjust these parameters to fit within the image boundaries.

"TypeError: unsupported image format"

• Explanation: This error occurs when the input image is in a format that the node cannot process.
• Solution: Convert the image to a compatible format, such as PNG or JPEG, before using the ImageCrop+ node.

"ValueError: invalid parameter value"

• Explanation: This error occurs when one or more input parameters are set to values outside their allowed ranges.
• Solution: Check the minimum, maximum, and default values for each parameter and ensure that your inputs fall within these ranges. Adjust any parameters that are set incorrectly.
