**Summary:** The BitmapV5Header structure is the bitmap information header file. It is an extended version of the BITMAPINFOHEADER structure.<br/>            <br/>If bV5Height is negative, indicating a top-down DIB, bV5Compression must be either BI_RGB or BI_BITFIELDS. Top-down DIBs cannot be compressed.<br/>            The Independent Color Management interface (ICM) 2.0 allows International Color Consortium (ICC) color profiles to be linked or embedded in DIBs (DIBs). <br/>            See Using Structures for more information. When a DIB is loaded into memory, the profile data (if present) should follow the color table, <br/>            and the bV5ProfileData should provide the offset of the profile data from the beginning of the BITMAPV5HEADER structure. <br/>            The value stored in bV5ProfileData will be different from the value returned by the sizeof operator given the BITMAPV5HEADER argument, <br/>            because bV5ProfileData is the offset in bytes from the beginning of the BITMAPV5HEADER structure to the start of the profile data. <br/>            (Bitmap bits do not follow the color table in memory). Applications should modify the bV5ProfileData member after loading the DIB into memory.<br/>            For packed DIBs, the profile data should follow the bitmap bits similar to the file format. <br/>            The bV5ProfileData member should still give the offset of the profile data from the beginning of the BITMAPV5HEADER.<br/>            Applications should access the profile data only when bV5Size equals the size of the BITMAPV5HEADER and bV5CSType equals PROFILE_EMBEDDED or PROFILE_LINKED.<br/>
