Parameters

The WIA version to be used. Possible values are:

Value

Meaning

WiaVersion.Version1 Use WIA version 1.0.
WiaVersion.Version2 Use WIA version 2.0.
Remarks

This method should be called before calling any other method in LEADTOOLS WIA toolkit. Likewise, when the handle to the WIA session is no longer needed, it should be ended by calling Shutdown method. For every call to Startup there must be a call to Shutdown.

Call the IsAvailable method to determine whether a WIA source with the specified version is installed.

Note:

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

For more information, refer to Initializing a WIA Session.

For more information, refer to Freeing the WIA Session.

Example

Refer to WiaSession.IsAvailable.
