iccwrite - Write ICC color profile to disk file
Syntax
P_new = iccwrite(P, filename)
Description
P_new = iccwrite(P, filename) writes
the International Color Consortium (ICC) color profile data in structure P to
the file specified by filename.
P is a structure representing an ICC profile
in the data format returned by iccread and used
by makecform and applycform to
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
was constructed. iccwrite makes any necessary corrections
to the profile structure before writing it to the file and returns
this corrected structure in P_new.
Note
Because some applications use the profile description string
in the ICC profile to present choices to users, the ICC recommends
modifying the profile description string in the ICC profile data before
writing the data to a file. Each profile should have a unique description
string. 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 Version field
in the file profile header. If any required fields are missing, iccwrite errors.
For more information about ICC profiles, visit the ICC web site, www.color.org.
Note
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 isicc to
validate a profile. |
Examples
Read a profile into the MATLAB workspace and export the
profile data to a new file. The example changes the profile description
string 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');See Also
