Hello, does anyone know of a method to determine if an

already been applied to an image? We'd like to avoid applying the same
profile twice to an image that is untagged. We've thought about
analyzing the gamut or individual channel response. Any other ideas?
In case of CMYK, try to convert the image again. If the differences
(caused by asymmetries between the A2B and B2A transforms) are below a
certain threshold, you can assume the conversion already happened.
