function RegisterPlugIns(PlugIns: TIEPlugIns = []; IEVisionUserEmail: WideString = ''; IEVisionUserSerial: WideString = ''; ExeFolderOnly: Boolean = True): TIEPlugIns;


Registers all available plug-in DLL's to add image formats and advanced functionality to ImageEn.
Parameter Description
PlugIns Which plug-ins to check for and load, or [] for all
IEVisionUserEmail, IEVisionUserSerial If you have purchased IEVision, then specify your email and serial number. Leave blank to run IEVision in trial mode
ExeFolderOnly Whether to search only the EXE folder or the system path for plug-ins. Setting to false may make the method much slower

You should call RegisterPlugIns once in your application (ideally at application start-up). There is no risk to calling RegisterPlugIns multiple times.

The following plug-ins are loaded if available:
