ComfyUI Node: ◎ Radiance DNA Writer

◎ Radiance DNA Writer:

The RadianceDNAWriter node is designed to embed metadata into images, effectively signing them with Radiance Digital DNA. This process involves adding specific metadata to each frame of an image batch, which can include details such as the project name, artist, and additional notes. The primary goal of this node is to ensure that images carry a digital signature that can be used for verification and tracking purposes. This is particularly useful in collaborative environments where maintaining the integrity and origin of digital assets is crucial. The node provides explicit feedback on the success or failure of the signing process, ensuring that users are informed about the status of their images.

◎ Radiance DNA Writer Input Parameters:

image

The image parameter is the primary input for the RadianceDNAWriter node. It accepts a batch of images that you wish to sign with Radiance Digital DNA. The images should be in a format that supports metadata embedding, and the node will process each frame individually if the batch contains multiple frames. There are no specific minimum or maximum values for this parameter, but the images should be compatible with the node's processing capabilities.

project

The project parameter allows you to specify the name of the project associated with the images. This information is embedded into the image metadata, providing context and traceability. While this parameter is optional, including it can help organize and identify images within larger projects. There are no predefined options or default values for this parameter.

artist

The artist parameter is used to include the name of the artist or creator of the images in the metadata. This is an optional field, but it can be valuable for attribution and recognition purposes. Like the project parameter, there are no predefined options or default values.

notes

The notes parameter provides a space for additional information or comments that you want to embed in the image metadata. This can include any relevant details that do not fit into the project or artist fields. This parameter is optional and does not have predefined options or default values.

◎ Radiance DNA Writer Output Parameters:

image

The image output parameter returns the batch of images with the embedded Radiance Digital DNA metadata. This output confirms that the images have been successfully signed and are ready for further use or distribution.

success

The success output parameter is a boolean value indicating whether the signing process was successful. A value of True means that the images were signed without issues, while False indicates that there was a problem during the process.

status

The status output parameter provides a detailed message about the signing process. This message includes information about the number of bits embedded, any special pixels preserved, and any errors encountered. It serves as a comprehensive report on the outcome of the operation.

◎ Radiance DNA Writer Usage Tips:

• Ensure that your images are in a compatible format that supports metadata embedding to avoid processing errors.
• Utilize the project, artist, and notes parameters to provide comprehensive metadata that can aid in the organization and identification of your images.
• Review the status output message to verify the success of the signing process and to understand any issues that may have occurred.

◎ Radiance DNA Writer Common Errors and Solutions:

"Error: Image format not supported"

• Explanation: This error occurs when the input image format does not support metadata embedding.
• Solution: Convert your images to a compatible format, such as PNG or TIFF, and try the process again.

"Error: Metadata embedding failed"

• Explanation: This error indicates that the node was unable to embed the metadata into the images.
• Solution: Check the status output for more details and ensure that the images are not corrupted or in a read-only state.

"Error: Invalid input parameters"

• Explanation: This error arises when one or more input parameters are not correctly specified.
• Solution: Verify that all required parameters are provided and correctly formatted, especially the image parameter.
