ComfyUI Node: ImageMagick Color Decision List

ImageMagick Color Decision List:

The ImageMagick Color Decision List node is designed to apply complex color corrections to your images using a standardized format known as the Color Decision List (CDL). This node allows you to fine-tune the color properties of your images by adjusting parameters such as slope, offset, power, and saturation. These adjustments are specified in a structured XML format, making it easy to apply consistent color corrections across multiple images. The primary benefit of using this node is its ability to provide precise and repeatable color adjustments, which is particularly useful for tasks that require high levels of color accuracy and consistency, such as professional photo editing, film production, and digital art creation.

ImageMagick Color Decision List Input Parameters:

image

This parameter accepts the image you want to apply the color corrections to. The image should be in a format that is compatible with ImageMagick, such as JPEG, PNG, or TIFF. The image serves as the base upon which the color corrections will be applied.

ccc

This parameter is a string that contains the Color Correction Collection (CCC) in XML format. The CCC specifies the color corrections to be applied, including slope, offset, power, and saturation values. The default value is a sample XML structure that demonstrates how to define these corrections. The XML should follow the CDL standard to ensure proper parsing and application of the corrections. This parameter supports multiline input to accommodate the XML structure.

ImageMagick Color Decision List Output Parameters:

IMAGE

The output is the image with the applied color corrections. This image will reflect the adjustments specified in the CCC XML, such as changes in slope, offset, power, and saturation. The output image maintains the same format as the input image but with the color corrections applied.

ImageMagick Color Decision List Usage Tips:

• Ensure that your CCC XML is well-formed and follows the CDL standard to avoid parsing errors.
• Use the default XML structure as a template to create your own color corrections.
• Experiment with different slope, offset, power, and saturation values to achieve the desired color effect.
• Apply the node to a test image first to verify the results before processing a batch of images.

ImageMagick Color Decision List Common Errors and Solutions:

Invalid XML Format

• Explanation: The CCC XML provided is not well-formed or does not follow the CDL standard.
• Solution: Double-check the XML structure for syntax errors and ensure it adheres to the CDL standard.

Unsupported Image Format

• Explanation: The input image is in a format that is not compatible with ImageMagick.
• Solution: Convert the image to a supported format such as JPEG, PNG, or TIFF before using the node.

Missing Color Correction Values

• Explanation: The CCC XML is missing required color correction values such as slope, offset, or power.
• Solution: Ensure that all required color correction values are specified in the XML.

Parsing Error

• Explanation: There was an error parsing the CCC XML.
• Solution: Validate the XML using an XML validator tool to identify and fix any issues.
