ComfyUI Node: QUEUE (JOV) 🗃

QUEUE (JOV) 🗃:

The Queue node is designed to manage a sequence of items, such as file paths or data entries, in a structured and efficient manner. It supports a variety of formats including images, videos, text files, and JSON files, making it versatile for different types of data processing tasks. This node allows you to specify the current index of the queue item, pause the queue, or reset it back to the first index. The primary benefit of using the Queue node is its ability to handle multiple items systematically, ensuring that each item is processed in the correct order. This is particularly useful for tasks that require batch processing or sequential handling of data. The node outputs the current item in the queue, the entire queue, the current index, and the total number of items in the queue, providing comprehensive control and monitoring of the queue's state.

QUEUE (JOV) 🗃 Input Parameters:

q

This parameter represents the queue of items, typically file paths or data entries, that you want to manage. It is a string that can contain multiple paths separated by newline characters. The queue is processed sequentially, and each item is handled according to the specified mode and other parameters. There is no explicit minimum or maximum value, but the default is an empty string.

mode

The mode parameter determines how the items in the queue are processed. It is a string that specifies the scaling mode for images, with options such as NONE, FIT, and others. The default value is NONE, which means no scaling is applied. This parameter impacts how images are resized and fitted within the specified dimensions.

wihi

This parameter specifies the width and height for processing images in the queue. It is a tuple of two integers, representing the dimensions (width, height). The default value is (512, 512), and it ensures that images are processed within these dimensions. The minimum value is the minimum image size supported by the system.

sample

The sample parameter defines the interpolation method used when scaling images. It is a string that can take values such as LANCZOS4, which is the default. This parameter affects the quality of the resized images, with different methods providing varying levels of smoothness and detail.

matte

This parameter specifies the matte color to be applied to images. It is a tuple of four integers (R, G, B, A), representing the red, green, blue, and alpha (transparency) channels. The default value is (0, 0, 0, 255), which corresponds to a fully opaque black color. The values range from 0 to 255 for each channel.

QUEUE (JOV) 🗃 Output Parameters:

ANY_OUT

This output represents the processed data from the queue. It can be any type of data, depending on the items in the queue and the processing applied.

QUEUE

This output provides the entire queue of items, allowing you to see all the entries being managed by the node.

CURRENT

This output gives the current item in the queue, indicating which item is currently being processed.

INDEX

This output represents the current index of the queue, showing the position of the current item within the queue.

TOTAL

This output provides the total number of items in the queue, giving you an overview of the queue's size.

QUEUE (JOV) 🗃 Usage Tips:

• Ensure that the file paths in the queue are correct and accessible to avoid processing errors.
• Use the mode parameter to control how images are scaled, especially if you need them to fit specific dimensions.
• Adjust the wihi parameter to match the desired output dimensions for your images.
• Experiment with different sample values to achieve the best quality for resized images.
• Use the matte parameter to apply a background color to images, which can be useful for transparency effects.

QUEUE (JOV) 🗃 Common Errors and Solutions:

bad file: [<file_path>]

• Explanation: This error occurs when the specified file path is incorrect or the file does not exist.
• Solution: Verify that the file path is correct and that the file exists at the specified location.

Unsupported file format

• Explanation: This error occurs when the file format is not supported by the node.
• Solution: Ensure that the file format is one of the supported formats, such as images, videos, text files, or JSON files.

Index out of range

• Explanation: This error occurs when the specified index is outside the range of the queue.
• Solution: Check the index value and ensure it is within the valid range of the queue's length.

Invalid interpolation method

• Explanation: This error occurs when an unsupported interpolation method is specified in the sample parameter.
• Solution: Use a valid interpolation method, such as LANCZOS4, NEAREST, or BILINEAR.
