Supported Environments

LEADTOOLS WIA supports both 32-bit and 64-bit image acquisition for both WIA 1.0 (XP and earlier) and WIA 2.0 (VISTA and later).


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 LWia::AcquireSimple handles session initialization, device selection, and session end automatically.
