The DataSource type exposes the following members.

Methods

	Name	Description
	Acquire(Boolean, Boolean, DataSourceErrorInfo, NullableTwSX, Int32)	Acquires images. Most simple way to scan. Preferred way for scanning in the console applications. Function will not return until scanning is finished.
	Acquire(IImageCollector, Boolean, Boolean, NullableTwSX, NullableInt32)	Allows to acquire images from the scanner synchronously. This function will not return until scanning is finished.
	AcquireAsync(IImageCollector, Boolean, Boolean, NullableTwSX, NullableInt32)	Allows to acquire images from the scanner asynchronously. This function will return immediately.
	AcquireAsync(ImageCollectorOnFinishedDelegate, Boolean, Boolean, NullableTwSX, NullableInt32)	Allows to acquire images from the scanner asynchronously.
	CallCustomTripletT
	CancelCurrentScanning	Cancels the current scanning.
	Dispose	Closes source and performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	(Overrides ObjectFinalize.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	SetupFileTransferParams(TwFF, IEnumerableString, Boolean)
	SetupFileTransferParams(TwFF, String, Boolean)
	ToString	Returns a String that represents the current Object. (Inherited from Object.)
