Re: [Lcms-user] Why is SetTextTags static?

[Marti M. <mar...@li...>]

Hi,

To change the description of a bult-in, as on any other profile you must 
use cmsWriteTag. Please note that description in V4 can be localized, so 
it is up to you to provide desciptions in as much languages as you need.

Basically you need to create a multi-localized unicode object.

cmsMLU* description = cmsMLUalloc(0, 1);  // I allocate space for just 
one language

Then populate it with the lacalized strings. I'm using ASCII here, but 
you can use unicode.

cmsMLUsetASCII(description, "EN", "us", "You nice description here");

And finally write the description

cmsWriteTag(hProfile, cmsSigDescriptionTag, description);

After that you can safely free the MLU object

cmsMLUfree(description);

If you save the profile as V2, only the first language is used.
This is done in such way because profiles can have tons of different 
infos, and a creation funcion with tons of parameters would be difficult 
to handle.

Hope it make sense to you.
Regards
Marti
