Comments

This feature is available in LEADTOOLS version 16 or higher.

This function will clean up and free memory allocated during the WIA session.

Whenever calling any of the LEADTOOLS WIA functions except for LWia::AcquireSimple. The LWia::InitSession function must be called to begin a session prior to calling the other function. For each call to LWia::InitSession there must be a call to LWia::EndSession to end the session. The LWia::EndSession function should be the last function to be called in the toolkit.

Note:

You do not need to call LWia::EndSession if you are using the high-level LWia::AcquireSimple function, since it handles session initialization, session end, and device selection automatically.
