LICCProfile::SetTagData

#include "ltwrappr.h"

L_INT LICCProfile::SetTagData(pTagData, uTagSig, uTagTypeSig);

L_UCHAR * pTagData;	/* pointer to a buffer */
L_UINT32 uTagSig;	/* tag signature */
L_UINT32 uTagTypeSig;	/* tag type signature */

Sets a tag inside the ICC profile.

Parameter	Description
pTagData	Pointer to a buffer that contains the tag data.
uTagSig	A value that represents the signature of the tag to be created. For all possible values including the private tags, refer to ICCTAGSIGNATURE. Signatures of private tags must be registered with the ICC.
uTagTypeSig	A value that represents the signature of the tag type used for creating the tag. For all possible values including the private tag type signatures, refer to ICCTAGTYPESIGNATURE. Signatures of private tag types must be registered with the ICC.

Returns

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

Comments

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 class object’s ICCPROFILEEXT member structure.
