TImageEnMIO.WIAParams


Declaration


property WIAParams: TIEWia;


Description


Provides access to parameters, dialogs and methods of connected WIA devices.

Note: Use WIAParams only when you need access to WIA specific functionality (when SelectedAcquireSource.Api is ieaWIA). For generic access to all image acquisitions sources (Twain, WIA, etc.) use AcquireParams instead.
