LICCProfile::GetTagData

#include "ltwrappr.h"

L_INT LICCProfile::GetTagData(pTagData, uTagSignature);

L_UCHAR * pTagData;	/* pointer to a buffer */
L_UINT32 uTagSignature;	/* tag signature */

Gets a tag from the ICC profile.

Parameter	Description
pTagData	Pointer to a buffer to be updated with the tag data.
uTagSignature	A value that indicates the signature of the tag to get from the ICC profile. For all possible values including the private tags, refer to ICCTAGSIGNATURE. Signatures of private tags 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 point to a structure of the same type as the tag type to be retrieved by this function. 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 pTagData parameter is updated correctly with the tag in the ICC profile.

   // Get Calibration Date and Time tag
   nRet = IccProfile.GetTagData ((L_UCHAR  *)(&IccDateTimeType), CalibrationDateTimeTag);
   // Free the ICC profile
   IccProfile.Free ();
