ComfyUI Node: Preview XY 🍌

Preview XY 🍌| Preview XY 🍌:

The PreviewXY| Preview XY 🍌 node is designed to generate a preview image from a set of input images and an XY list, which is particularly useful for visualizing the results of various model configurations in AI art generation. This node allows you to combine multiple images into a single composite image, providing a clear and organized way to compare different outputs side by side. The primary goal of this node is to facilitate the evaluation and comparison of different model outputs, making it easier to identify the best configurations and settings for your AI art projects. By using this node, you can save time and effort in manually combining images and ensure a consistent and professional presentation of your results.

Preview XY 🍌| Preview XY 🍌 Input Parameters:

images

This parameter expects a list of images that you want to include in the preview. Each image should be in the format specified by the node, typically as a tensor or array. The images will be combined into a single composite image based on the XY list provided. This parameter is crucial as it determines the visual content of the preview.

xy_list

The xy_list parameter is a list of labels or identifiers that correspond to the images provided. This list is used to annotate the composite image, making it clear which image corresponds to which model configuration or setting. The xy_list helps in organizing and labeling the images in the preview, ensuring that the comparison is easy to understand.

prompt

This hidden parameter is used to include any prompt information that might be relevant to the images. It is not required for the basic functionality of the node but can be useful for keeping track of the prompts used to generate the images.

extra_pnginfo

Another hidden parameter, extra_pnginfo, is used to store additional metadata or information about the images. This can include details such as the model settings, generation parameters, or any other relevant data that might be useful for future reference.

Preview XY 🍌| Preview XY 🍌 Output Parameters:

ui

The output parameter ui contains the results of the preview generation process. It includes a list of dictionaries, each containing information about the generated preview image, such as the filename, subfolder, and type. This output is essential for accessing and utilizing the generated preview images, allowing you to easily locate and view the results of your model comparisons.

Preview XY 🍌| Preview XY 🍌 Usage Tips:

• Ensure that the images provided are in the correct format and resolution to avoid any issues during the preview generation process.
• Use a clear and descriptive xy_list to label the images effectively, making it easier to compare and analyze the results.
• Take advantage of the prompt and extra_pnginfo parameters to store relevant metadata and prompts, which can be useful for future reference and analysis.

Preview XY 🍌| Preview XY 🍌 Common Errors and Solutions:

"Invalid image format"

• Explanation: This error occurs when the images provided are not in the expected format or resolution.
• Solution: Ensure that all images are in the correct format and resolution as specified by the node documentation.

"XY list length mismatch"

• Explanation: This error happens when the length of the xy_list does not match the number of images provided.
• Solution: Verify that the xy_list contains the same number of entries as the number of images provided to the node.

"File save error"

• Explanation: This error occurs when there is an issue saving the generated preview image to the specified directory.
• Solution: Check the file path and directory permissions to ensure that the node has the necessary access to save the files.
