LICCProfile::GetTagData

#include "ltwrappr.h"

L_INT LICCProfile::GetTagData(pTagData, uTagSignature);

Gets a tag from the ICC profile.

Parameters

L_UCHAR * pTagData

Pointer to a buffer to be updated with the tag data.

L_UINT32 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

Value Meaning
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.

Example

This example will load an ICC profile, get a tag, and then free the ICC profile

L_INT LICCProfile_GetTagDataExample(L_TCHAR* szFileName) 
{ 
   L_INT nRet = FAILURE;  
   LICCProfile IccProfile;  
   ICCTAG_DATE_TIME_TYPE IccDateTimeType;  
 
   // Initialize the ICC Profile 
   nRet = IccProfile.Initialize (); 
   if (nRet != SUCCESS) 
   { 
      IccProfile.Free (); 
      return nRet; 
   } 
   // Load an ICC Profile that is embedded in an image 
   nRet = IccProfile.Load (szFileName, NULL); 
   if (nRet != SUCCESS) 
   { 
      IccProfile.Free (); 
      return nRet; 
   } 
 
   // Fill the ICC Profile with the ICC data loaded from the image 
   nRet = IccProfile.Fill (IccProfile.GetProfile ()->pData, (L_UINT)(IccProfile.GetProfile()->uDataSize)); 
   if (nRet != SUCCESS) 
   { 
      IccProfile.Free (); 
      return nRet; 
   } 
 
   // Get Calibration Date and Time tag 
   nRet = IccProfile.GetTagData ((L_UCHAR  *)(&IccDateTimeType), CalibrationDateTimeTag); 
 
   // Free the ICC Profile 
   IccProfile.Free (); 
   return nRet; 
}
