There are several functions/methods to retrieve the version number of the DLL or ActiveX. For example: GetImageVersion (BiDIB), GetTiffVersion (BiTiff), GetBiFilterVersion (BiFilter).

/* 1. parameter: Handle of the DIB
2. parameter: X coordinate of the pixel
3. parameter: Y coordinate of the pixel
4. parameter: Color value
GetImageVersion(szVersion, 255);
[C#]
/* Checking the Black Ice Imaging Toolkit version number*/
string szVersion;
szVersion = BiDIB.GetimageVersion();
