IccProfileExtended Class

Summary
Contains all of the data for a complete ICC profile.
Syntax
C#
C++
public class IccProfileExtended 
vb[VB Syntax] 
  
Public Class IccProfileExtended 
public ref class IccProfileExtended  
Remarks
  • The data in all the members (except for the data in the tagData and the data arrays)is converted into Little Endian format.
  • The data in the data member and tagData array is not directly accessed. ICC defined methods use the data in them, so they are kept in Big Endian format.
  • When an existing ICC profile is loaded into this structure, the data member contains all of the profile data as one block of memory. The TagData array contains only the tag data in one block of memory.
  • Whether a new ICC profile is being created or an existing one is being modified, the TagData always contains the right values. The Data array, however, will not contain the correct values until a call to the UpdateDataArray method is made. This call updates the Data array with the latest modifications.
