ComfyUI Node: Load metadata from image

Load metadata from image:

The LF_LoadMetadata node is designed to extract metadata from image files, making it a valuable tool for AI artists who need to analyze and utilize image information. This node simplifies the process of retrieving metadata from various image formats, such as JPEG and PNG, and compiles this data into a structured JSON format. By automating the extraction of metadata, LF_LoadMetadata helps you save time and ensures accuracy, allowing you to focus on the creative aspects of your work. Whether you are managing a large collection of images or need specific metadata for your projects, this node provides a streamlined and efficient solution.

Load metadata from image Input Parameters:

file_names

This parameter expects a string containing a list of file names separated by semicolons (e.g., file1.jpg;file2.png;file3.jpg). It specifies the image files from which metadata will be extracted. The function of this parameter is to provide the node with the necessary file paths to process. The impact on the node's execution is significant, as it determines which files are analyzed. There are no minimum or maximum values, but the file names must be valid and accessible within the input directory. The default value is an empty string, and it is required to be filled for the node to function correctly.

Load metadata from image Output Parameters:

metadata_list

This output parameter returns a JSON object containing a list of metadata for each specified image file. Each entry in the list includes the file name and its corresponding metadata or an error message if the file could not be processed. The function of this parameter is to provide a comprehensive and structured output of the extracted metadata, which can be used for further analysis or integration into other workflows. The importance of this output lies in its ability to deliver detailed and organized information about the images, facilitating better decision-making and creative processes.

Load metadata from image Usage Tips:

• Ensure that the file names provided in the file_names parameter are correctly formatted and accessible within the input directory to avoid errors during execution.
• Use this node to quickly gather metadata from a batch of images, which can be particularly useful for organizing and categorizing large image collections.
• Combine this node with other nodes that process or analyze JSON data to create a more comprehensive workflow for your projects.

Load metadata from image Common Errors and Solutions:

Unsupported image format for <file_name>

• Explanation: This error occurs when the node encounters an image format that it does not support.
• Solution: Ensure that the image files are in JPEG or PNG format, as these are the supported formats for metadata extraction.

[Errno 2] No such file or directory: '<file_path>'

• Explanation: This error indicates that the specified file could not be found in the input directory.
• Solution: Verify that the file names are correct and that the files are located in the designated input directory.

cannot identify image file '<file_path>'

• Explanation: This error suggests that the node was unable to open or recognize the image file.
• Solution: Check if the file is a valid image and not corrupted. Ensure that the file extension matches the actual file format.

<file_name> - <error_message>

• Explanation: This is a generic error message indicating that an exception occurred while processing the file.
• Solution: Review the specific error message provided to diagnose the issue. Common problems include file access permissions, unsupported file formats, or corrupted files.
