Create a new ICC profile data without the header and copyright fields. Usermfieldto remove the 'Header' and 'Copyright' fields from the ICC profile data structure.

newProfile = rmfield(profile,{'Header','Copyright'});

Inspect the new profile data to verify that the 'Header' and 'Copyright' fields are removed.

Algorithms

isiccchecks ifprofilehas a complete set of the tags required for an ICC profile.profilemust contain aHeaderfield, which in turn must contain aVersionfield and aDeviceClassfield. These fields along with others, are used to determine the set of required tags according to the ICC profile specification. The required tags for ICC profile specifications related to Version 2 (ICC.1:2001-04) and Version 4 (ICC.1:2001-12) are available athttps://www.color.org.
