ComfyUI Node: Uncrop (mtb)

Uncrop (mtb):

The Uncrop (mtb) node is designed to reverse the cropping process on images, effectively restoring the original dimensions and context that were previously reduced. This node is particularly useful for AI artists who need to revert their images to their initial state after performing cropping operations for various purposes such as focusing on specific details or optimizing processing tasks. By using the Uncrop (mtb) node, you can seamlessly integrate the cropped sections back into the original image, ensuring that no information is lost and maintaining the integrity of the artwork. This node is essential for workflows that require iterative editing and refinement, providing a flexible and efficient way to manage image dimensions and content.

Uncrop (mtb) Input Parameters:

crop_imgs

This parameter represents the list of cropped images that you want to uncrop. Each image in this list will be processed to restore its original dimensions and context. The function of this parameter is to provide the necessary input data for the uncropping operation. There are no specific minimum, maximum, or default values for this parameter, as it depends on the images you have previously cropped and wish to revert.

original_dims

This parameter specifies the original dimensions of the images before they were cropped. It is crucial for accurately restoring the images to their initial state. The function of this parameter is to guide the uncropping process by providing the target dimensions for each image. The values for this parameter should match the dimensions of the images before cropping, ensuring a precise and accurate uncropping operation.

Uncrop (mtb) Output Parameters:

uncropped_imgs

This output parameter represents the list of images that have been successfully uncropped. Each image in this list has been restored to its original dimensions and context, as specified by the input parameters. The function of this parameter is to provide the final result of the uncropping operation, allowing you to continue your workflow with the images in their initial state. The interpretation of this output is straightforward: it contains the images that have been reverted to their original form, ready for further editing or final use.

Uncrop (mtb) Usage Tips:

• Ensure that the original_dims parameter accurately reflects the dimensions of the images before they were cropped to achieve precise uncropping results.
• Use the Uncrop (mtb) node in conjunction with the Crop (mtb) node to create a flexible and iterative editing workflow, allowing you to focus on specific details and then revert to the full image as needed.

Uncrop (mtb) Common Errors and Solutions:

"Dimension mismatch error"

• Explanation: This error occurs when the dimensions specified in the original_dims parameter do not match the actual dimensions of the cropped images.
• Solution: Double-check the original_dims parameter to ensure it accurately reflects the original dimensions of the images before cropping. Correct any discrepancies and try again.

"Invalid input type error"

• Explanation: This error occurs when the input provided to the crop_imgs parameter is not a valid list of images.
• Solution: Verify that the input to the crop_imgs parameter is a list of images that were previously cropped. Ensure the data type is correct and retry the operation.
