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


Registers all available plug-in DLLs to add image formats and advanced functionality to ImageEn.
Parameter Description
PlugIns Which plug-ins to check for and load, or [] for all
DLLPath Optionally, specify the folder containing the add-in DLLs (if not the EXE folder or system path)
IEVisionUserEmail, IEVisionUserSerial If you have purchased IEVision 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:
Plug-In Const Description Equivalent Methods
IELib iepiIELib Support for Camera Raw formats, and faster loading of JPEG, PNG and JPEG2000 IELibAvailable
IEVision iepiIEVision Advanced functionality plug-in IEVisionSetSerialNumber and IEVisionAvailable
IELang iepiLanguages Localization of the ImageEn user interface and actions in over twenty languages IELangAvailable
PDFium iepiPDFium Viewing and manipulation of PDF files PDFiumLibAvailable
ImageMagick iepiImageMagick Support for a wider range of image formats (supports both installed and DLL-only versions) IsAvailable and RegisterPlugin
SevenZip iepiSevenZip Support for ZIP files -

Most plug-ins can be downloaded from:

Result is equivalent to: ActivePlugIns

 If loading fails, you can get debugging information from: DLLLoadingLog
 The expected version of IELib/IEVision is available from: ImageEnVersion.IELibVersionStr
 Registering of the IELib, IELang and PDFium plug-ins is optional as they will be automatically registered when they are first needed (if found in your EXE folder)
 To register the legacy ImageMagick plug-In, ImageMagick.dll use: IEAddExtIOPlugIn
