ComfyUI Node: 🪛 Load image with metadata

Load image with metadata [Crystools]:

The "Load image with metadata [Crystools]" node is designed to load an image along with its associated metadata, making it a powerful tool for AI artists who need to work with images that contain embedded information. This node not only loads the image but also extracts and processes metadata such as prompts and additional information stored within the image file. This can be particularly useful for workflows that require the use of metadata for further processing or analysis, ensuring that all relevant information is preserved and accessible.

Load image with metadata [Crystools] Input Parameters:

image

The image parameter specifies the path to the image file that you want to load. This parameter is crucial as it directs the node to the correct file from which to extract both the image and its metadata. Ensure that the file path is accurate and that the file exists to avoid errors during execution.

Load image with metadata [Crystools] Output Parameters:

image

The image output is the loaded image converted into a format suitable for further processing. The image is transformed into a tensor format, normalized to a range of 0 to 1, which is ideal for machine learning models and other image processing tasks.

mask

The mask output is a tensor representing the alpha channel of the image, if it exists. This mask can be used for various purposes, such as masking out certain parts of the image during processing. If the image does not have an alpha channel, a default mask of zeros is provided.

prompt

The prompt output contains the prompt metadata extracted from the image. This is useful for applications that need to utilize or display the prompt information embedded within the image file.

metadata

The metadata output is a dictionary containing all the additional metadata extracted from the image. This can include various types of information stored within the image file, providing a comprehensive set of data for further use.

Load image with metadata [Crystools] Usage Tips:

• Ensure that the image file path provided is correct and that the file exists to avoid errors during execution.
• Utilize the prompt and metadata outputs to access and use the embedded information within the image for more informed processing and analysis.
• If working with images that have an alpha channel, make use of the mask output to handle transparency effectively in your workflows.

Load image with metadata [Crystools] Common Errors and Solutions:

Invalid image file: <image_path>

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

Error parsing metadataFromImg 'workflow'

• Explanation: This error indicates that there was an issue parsing the workflow metadata from the image.
• Solution: Ensure that the workflow metadata is correctly formatted as JSON within the image file.

Error parsing metadataFromImg 'prompt'

• Explanation: This error signifies a problem with parsing the prompt metadata from the image.
• Solution: Check that the prompt metadata is properly formatted as JSON in the image file.

Error parsing <key> as json, trying as string

• Explanation: This error occurs when a piece of metadata could not be parsed as JSON and is being attempted to be parsed as a string.
• Solution: Ensure that all metadata values are correctly formatted as JSON or valid strings within the image file.
