L_LTCLR_API L_INT L_SetICCTagData(pICCProfile, pTagData, uTagSig, uTagTypeSig)

Sets a tag inside the ICC profile.



Pointer to the ICCPROFILEEXT structure in which to set the tag.

L_UCHAR* pTagData

Pointer to a buffer that contains the tag data.

L_UINT uTagSig

A value that indicates the signature of the tag to be created. Possible values include private tags and the values listed in ICCTAGSIGNATURE. Signatures of private tags must be registered with the ICC.

L_UINT uTagTypeSig

A value that indicates the signature of the tag type used for creating the tag. Possible values include private tag type signatures and the values listed in ICCTAGTYPESIGNATURE. Signatures of private tag types must be registered with the ICC.


Value Meaning
SUCCESS The function was successful.
< 1 An error occurred. Refer to Return Codes.


The pTagData pointer should be a pointer to a structure that contains all the data required for the tag to be created. This structure should be of the same type as the ICC tag type required for the tag to be created. In case of a private tag type, the pTagData must point to a structure of type ICCTAG_UNKNOWN_TYPE.

If only the tag is private, this function returns ERROR_ICC_UNKNOWN_TAG. If only the tag type is private, this function returns ERROR_ICC_UNKNOWN_TYPE. If both the tag and the type are private, this function returns ERROR_ICC_UNKNOWN_TAG_AND_TYPE. In all three of these cases however, the tag is set correctly in the ICC profile.

To add multiple tags to a profile, call this function repeatedly. Each subsequent tag added is appended to the list of tags pointed to by the pTagData member of the ICC profile structure.
