KcsProfileFormat Example

If you derive from the KcsProfileFormat class, you need to provide a KcsProfileFormat class entry such as the example entries below:

#Profile

format class, default is ICC #Default profile format, ICC, default CMM

class="KCS_Pfmt" name="acspdflt"

	kcsLoadableModule="kcsEKPfmticc30.so.1";  #ICC profile format,

KCMS CMM class="KCS_Pfmt" name="acspKCMS"

	kcsLoadableModule="kcsEKPfmticc30.so.1";

The profile format is determined from the profile file signature (also known as the magic number), which is contained in bytes 36-39 in the ICC profile header), and CMM Id (bytes 4-7 in the header). (See "ICC Profile Header".) A check is performed to ensure that an ICC profile uses the magic number of the file. If another format is used, the magic number is used to load the module.

All profiles that are ICC profile format files should have a magic number equal to acsp, and they must have the ICC header included. The CMM Id is used to match the profile format with the correct derivative. If no match is found, the default entry (dflt) is used; therefore, you can use the supplied default profile format class for ICC profiles.

The name field syntax is: <Profile magic number><CMM Id>

The OWconfig file entry must match the resulting name. This also gives color management vendors the opportunity to support pre-ICC format profiles, provided they include the ICC header.
