ComfyUI Node: Image Paste Crop by Location

Image Paste Crop by Location:

The Image Paste Crop by Location node is designed to facilitate precise image manipulation by allowing you to crop a specific region from an image and then paste it back onto another image at a designated location. This node is particularly useful for tasks that require detailed image editing, such as creating composite images, correcting specific areas, or enhancing particular sections of an image. By providing control over the cropping dimensions and the paste location, this node ensures that you can achieve the desired visual effect with high accuracy. The node also includes options for blending and sharpening the pasted image, which helps in seamlessly integrating the cropped section with the target image.

Image Paste Crop by Location Input Parameters:

image

This parameter represents the source image from which a region will be cropped. The image should be in a compatible format that the node can process.

x

This parameter specifies the x-coordinate of the center point for the cropping region. It determines the horizontal position of the crop area within the source image. The value must be an integer between 0 and the maximum resolution of the image, with a default value of 256.

y

This parameter specifies the y-coordinate of the center point for the cropping region. It determines the vertical position of the crop area within the source image. The value must be an integer between 0 and the maximum resolution of the image, with a default value of 256.

size

This parameter defines the size of the square region to be cropped from the source image. The value must be an integer, typically set to 512 by default, and it determines the width and height of the cropping area.

crop_image

This parameter represents the cropped image that will be pasted onto the target image. It should be the output from the cropping operation.

crop_data

This parameter contains metadata about the cropped region, including its size and coordinates. It is used to accurately place the cropped image onto the target image.

blend_amount

This parameter controls the blending intensity between the cropped image and the target image. The value ranges from 0 to 1, with a default value of 0.25. A higher value results in a more blended appearance.

sharpen_amount

This parameter determines the amount of sharpening applied to the pasted image. The value ranges from 0 to 1, with a default value of 1. A higher value results in a sharper pasted image.

Image Paste Crop by Location Output Parameters:

image

This output parameter represents the final image after the cropped region has been pasted onto the target image. The image is returned in a format compatible with further processing or display.

crop_data

This output parameter provides metadata about the cropped region, including its size and coordinates. This information is useful for further image manipulation or for reference purposes.

Image Paste Crop by Location Usage Tips:

• Ensure that the x and y coordinates for cropping are within the bounds of the source image to avoid errors.
• Use the blend_amount parameter to achieve a seamless integration of the cropped region with the target image, especially when dealing with complex backgrounds.
• Adjust the sharpen_amount parameter to enhance the clarity of the pasted image, particularly if the cropped region contains fine details.

Image Paste Crop by Location Common Errors and Solutions:

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

• Explanation: This error occurs when the specified crop dimensions result in a region with zero or negative width or height.
• Solution: Verify that the top, left, right, and bottom values are set correctly and that they define a valid rectangular region within the source image.

Image dimensions exceed maximum resolution.

• Explanation: This error occurs when the specified crop or paste dimensions exceed the maximum allowed resolution for the image.
• Solution: Ensure that the width, height, x, and y parameters are within the maximum resolution limits of the image.

Blending or sharpening values out of range.

• Explanation: This error occurs when the blend_amount or sharpen_amount parameters are set outside their valid range of 0 to 1.
• Solution: Adjust the blend_amount and sharpen_amount parameters to be within the range of 0 to 1.
