This feature is available in LEADTOOLS version 16 or higher.


The LWia class is derived from LScanner and provides support for acquiring images from WIA compatible data sources such as scanners, digital cameras and streaming videos. This class provides functionality for enumerating and selecting WIA data sources, displaying the data source's built-in user interface, acquiring single or multiple images, and setting acquisition parameters without using the built-in UI.

Required Libraries

You must load all required libraries using LBase::LoadLibraries before using the classes.


For a listing of the exact DLLs and Libraries needed, based on the toolkit version, refer to Files To Be Included With Your Application.
