ComfyUI Node: ImageBatchCopy

ImageBatchCopy:

The ImageBatchCopy node is designed to duplicate a specific image within a batch multiple times. This can be particularly useful when you need to create multiple copies of a single image for further processing or analysis. By specifying the index of the image you want to copy and the number of copies you need, this node efficiently generates the desired quantity of duplicates. This functionality is essential for tasks that require repeated instances of the same image, such as data augmentation, testing, or creating variations of a single image for artistic purposes.

ImageBatchCopy Input Parameters:

images

This parameter represents the batch of images from which you want to copy a specific image. The batch is typically a tensor containing multiple images stacked together. Each image in the batch should have the same dimensions and number of channels.

index

The index parameter specifies the position of the image within the batch that you want to copy. The index is 1-based, meaning that an index of 1 refers to the first image in the batch. The default value is 1, the minimum value is 1, and the step value is 1. This parameter allows you to select the specific image you want to duplicate.

quantity

The quantity parameter determines the number of copies to create of the selected image. The default value is 1, the minimum value is 2, and the step value is 1. This parameter allows you to specify how many duplicates of the selected image you need, enabling you to generate the required number of copies for your task.

ImageBatchCopy Output Parameters:

images

The output is a batch of images where the selected image has been duplicated the specified number of times. The resulting tensor contains the repeated instances of the chosen image, stacked together. This output can be used for further processing or analysis in your workflow.

ImageBatchCopy Usage Tips:

• To duplicate the first image in a batch five times, set the index parameter to 1 and the quantity parameter to 5.
• Ensure that the index parameter does not exceed the number of images in the batch to avoid errors.
• Use this node to create multiple copies of an image for data augmentation or testing purposes.

ImageBatchCopy Common Errors and Solutions:

IndexError: index out of range

• Explanation: This error occurs when the specified index parameter exceeds the number of images in the batch.
• Solution: Ensure that the index parameter is within the range of the batch size. The maximum value for index should be equal to the number of images in the batch.

ValueError: quantity must be at least 2

• Explanation: This error occurs when the quantity parameter is set to a value less than 2.
• Solution: Set the quantity parameter to a value of 2 or higher to create at least two copies of the selected image.
