L_UINT32 uTagSig;	tag signature
L_UCHAR * pTag;	pointer to a buffer of data

Deletes a tag from the ICC profile.

Parameter	Description
uTagSig	A value that indicates the signature of the tag to delete from the ICC profile. For all possible values including the private tag types, refer to ICCTAGSIGNATURE.
pTag	Pointer to a buffer to be updated with the deleted tag.

Returns

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

Example

This example will delete a tag from an ICC profile

L_INT LICCProfile_DeleteTagExample(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); 
   if (nRet != SUCCESS) 
   { 
      IccProfile.Free (); 
      return nRet; 
   } 
   nRet = IccProfile.DeleteTag(CalibrationDateTimeTag, (L_UCHAR  *)(&IccDateTimeType)); 
   // Free the ICC Profile 
   IccProfile.Free (); 
   return nRet;
