the International Color Consortium (ICC) color profile data in structure
the file specified by
P is a structure representing an ICC profile
in the data format returned by
iccread and used
compute color-space transformations.
P must contain
all the tags and fields required by the ICC profile specification.
Some fields may be inconsistent, however, because of interactive changes
to the structure. For instance, the tag table may not be correct because
tags may have been added, deleted, or modified since the tag table
iccwrite makes any necessary corrections
to the profile structure before writing it to the file and returns
this corrected structure in
Because some applications use the
in the ICC profile to present choices to users, the ICC recommends
modifying the profile description in the ICC profile data before writing
the data to a file. Each profile should have a unique profile description.
For more information, see the example.
iccwrite can write the color profile data
using either Version 2 (ICC.1:2001-04) or Version 4 (ICC.1:2001-12)
of the ICC specification, depending on the value of the
in the file profile header. If any required fields are missing,

iccwrite does not perform automatic conversions
from one version of the ICC specification to another. Such conversions
have to be done manually, by adding fields or modifying fields. Use
validate a profile.
Read a profile into the MATLAB® workspace and export the profile data to a new file. The example changes the profile description in the profile data before writing the data to a file.
P = iccread('monitor.icm'); P.Description.String ans = sgC4_050102_d50.pf P.Description.String = 'my new description'; pmon = iccwrite(P, 'monitor2.icm');
