LWia

This feature is available in LEADTOOLS version 16 or higher.

Description

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. Use this class to enumerate and select WIA data sources, display the data source's built-in user interface, acquire single or multiple images, and set acquisition parameters without using the built-in UI.

Notes

WIA 2.0 does not support cameras or streaming video.

If you are using the high-level LWia::AcquireSimple, you do not need to call LWia::InitSession, LWia::SelectDevice, or LWia::EndSession because it handles session initialization, device selection, and session end automatically.

Required Libraries Be sure to load all required libraries using LBase::LoadLibraries before using the classes.
