ComfyUI Node: JDCN_BatchImageLoadFromList

JDCN_BatchImageLoadFromList:

The JDCN_BatchImageLoadFromList node is designed to facilitate the batch loading of images from a specified list of file paths. This node is particularly useful for AI artists who need to process multiple images in a structured and efficient manner. By specifying parameters such as the batch size, index, and direction, you can control how images are loaded and processed. The node supports various loading directions, including top-to-bottom, bottom-to-top, and random, providing flexibility in how batches are created. This functionality is essential for tasks that require handling large sets of images, such as training machine learning models or generating art from multiple sources.

JDCN_BatchImageLoadFromList Input Parameters:

PathList

This parameter expects a string that represents a list of file paths to the images you want to load. It is a required input and must be provided for the node to function correctly. The list should be formatted as a single string with paths separated by commas or another delimiter.

Index

The Index parameter is an integer that specifies the starting point for loading images from the list. It has a default value of 1, with a minimum value of 1 and a maximum value of 9999. This parameter allows you to control which part of the list to start loading images from, making it easier to manage large datasets.

BatchSize

The BatchSize parameter determines the number of images to load in each batch. It is an integer with a default value of 5, a minimum value of 0, and a maximum value of 9999. This parameter is crucial for controlling the size of each batch, allowing you to process images in manageable chunks.

BatchDirection

The BatchDirection parameter specifies the direction in which images are loaded from the list. It offers three options: "TOPTOBOTTOM", "BOTTOMTOTOP", and "RANDOM". This parameter provides flexibility in how batches are created, enabling different loading strategies based on your specific needs.

JDCN_BatchImageLoadFromList Output Parameters:

Images

This output contains the loaded images in the form of a list. Each image is represented in a format suitable for further processing or analysis. This output is essential for any subsequent operations that require the actual image data.

ImageNames

The ImageNames output provides a list of the names of the loaded images. This is useful for keeping track of which images have been processed, especially when dealing with large datasets.

ImagePaths

The ImagePaths output returns a list of the file paths of the loaded images. This is helpful for referencing the original files and for any operations that may require the file paths.

Index

The Index output returns the index from which the images were loaded. This is useful for tracking the progress of batch loading, especially when processing large lists of images.

JDCN_BatchImageLoadFromList Usage Tips:

• Ensure that the PathList is correctly formatted and contains valid file paths to avoid errors during image loading.
• Adjust the BatchSize according to your system's memory capacity to prevent overloading and ensure smooth processing.
• Use the BatchDirection parameter to experiment with different loading strategies and find the one that best suits your workflow.

JDCN_BatchImageLoadFromList Common Errors and Solutions:

"Direction must be one of {'TOPTOBOTTOM', 'BOTTOMTOTOP', 'RANDOM'}."

• Explanation: This error occurs when an invalid direction is specified in the BatchDirection parameter.
• Solution: Ensure that the BatchDirection parameter is set to one of the valid options: "TOPTOBOTTOM", "BOTTOMTOTOP", or "RANDOM".

"Input list is empty."

• Explanation: This error occurs when the PathList parameter is empty or not provided.
• Solution: Make sure to provide a valid list of file paths in the PathList parameter.

"Start index is out of range."

• Explanation: This error occurs when the specified Index is outside the range of the PathList.
• Solution: Adjust the Index parameter to a value within the range of the list of file paths provided in the PathList.
