DTwainBufferedTransfer::GetStrip

Syntax

HANDLE DTwainBufferedTransfer::GetStrip( ) const;

Return Value

Returns a HANDLE to the currently acquired strip of data.

Comments

The GetStrip function returns a HANDLE to the last strip of image data that was acquired.  This function should only be used when calling an overridden function in the DTwainBufferedListener object (for example DTwainBufferedListener::OnTransferStripDone) since it only returns a valid HANDLE during the image acquisition process.

The application must call the Windows API GlobalLock( ) on the HANDLE to create a useful pointer to the data.  After the application is done, the GlobalUnlock( ) function must be called.
