ComfyUI Node: CROP (JOV) ✂️

CROP (JOV) ✂️:

The CROP (JOV) ✂️ node is designed to provide versatile cropping capabilities for your images, allowing you to focus on specific areas of interest or to fit images into desired dimensions. This node supports various cropping modes, including freeform polygonal cropping, XY coordinate-based cropping, and center cropping. By leveraging these functionalities, you can enhance your image composition, remove unwanted sections, or prepare images for further processing. The CROP (JOV) ✂️ node is particularly useful for AI artists who need precise control over their image layouts and want to streamline their workflow with efficient cropping techniques.

CROP (JOV) ✂️ Input Parameters:

pA

This parameter represents the input image to be cropped. If no image is provided, a solid channel image will be used as a default. The input image is converted from a tensor to an OpenCV format for processing.

func

This parameter determines the cropping mode to be used. It can take values from the EnumCropMode enumeration, such as FREE, XY, HEAD, BODY, or CENTER. Each mode specifies a different method of cropping the image. For example, FREE allows for polygonal cropping based on specified points, while CENTER crops the image around its center.

wihi

This parameter specifies the width and height of the cropping area. It is used to define the dimensions of the cropped image, ensuring that the output fits the desired size.

tltr

This parameter is used in the FREE cropping mode and represents the top-left and top-right coordinates of the cropping polygon. These coordinates are normalized values between 0 and 1, indicating the relative position within the image.

blbr

This parameter is also used in the FREE cropping mode and represents the bottom-left and bottom-right coordinates of the cropping polygon. Similar to tltr, these coordinates are normalized values between 0 and 1.

xy

This parameter is used in the XY cropping mode and specifies the X and Y coordinates for cropping. It allows for precise cropping based on specific pixel positions within the image.

color

This parameter defines the color to be used for the cropped area. It is particularly useful when the cropped area needs to be filled with a specific color, ensuring consistency in the output image.

CROP (JOV) ✂️ Output Parameters:

Cropped Image

The output is a tensor representing the cropped image. This tensor can be used for further processing or as a final output, depending on your workflow. The cropped image retains the specified dimensions and cropping mode applied during the process.

CROP (JOV) ✂️ Usage Tips:

• Use the FREE mode for complex cropping shapes by specifying the polygonal coordinates.
• For simple center cropping, the CENTER mode is the most straightforward and efficient.
• Adjust the wihi parameter to ensure the cropped image fits your desired dimensions.
• Utilize the color parameter to fill the cropped area with a specific color, maintaining visual consistency.

CROP (JOV) ✂️ Common Errors and Solutions:

"Invalid cropping mode specified"

• Explanation: The func parameter was set to an invalid value not recognized by the EnumCropMode enumeration.
• Solution: Ensure that the func parameter is set to one of the valid values: FREE, XY, HEAD, BODY, or CENTER.

"Coordinates out of bounds"

• Explanation: The coordinates specified in tltr or blbr are outside the valid range of 0 to 1. - Solution: Verify that all coordinates are normalized values between 0 and 1, representing relative positions within the image.

"Image dimensions not specified"

• Explanation: The wihi parameter was not provided, leading to undefined dimensions for the cropping area.
• Solution: Ensure that the wihi parameter is set with the desired width and height for the cropping area.

"Input image not provided"

• Explanation: No input image was provided, and the default solid channel image is not suitable for the intended cropping.
• Solution: Provide a valid input image to be cropped, ensuring it is in the correct format for processing.
