Public Property TransferMechanism As TwainTransferMechanism

'Usage

Dim instance As TwainDataTransferProperties
Dim value As TwainTransferMechanism

value = instance.TransferMechanism

public:
property TwainTransferMechanism TransferMechanism {
   TwainTransferMechanism get();
   void set (    TwainTransferMechanism value);

Property Value

Transfer mode to be used by the TWAIN source. Possible values are (according to the TWAIN 2.0 specification):

TwainCapabilityValue.TransferMechanismNative Native transfer mode.
TwainCapabilityValue.TransferMechanismMemory Memory buffered transfer mode. The source will be transferring strips of data to the application according to the buffer size given.
TwainCapabilityValue.TransferMechanismFile File transfer mode. This will use a specified file to have the image data saved to. This will have a certain format specified by the properties.

If you set the TransferMode property to TransferMechanismMemory and set DumpMemoryBuffersToFile to true, then the Acquire method will write the received buffers (either compressed or uncompressed) to the output directly to the output file specified by the FileName property.
If you set the TransferMode property to TransferMechanismMemory and a compression is specified by setting the BufferedMemoryCompression property, and you set the DumpMemoryBuffersToFile property to false, then the Acquire method will decompress the acquired data and generate a result image.
