Property Value

Flag that indicates whether to use double buffering while doing memory transfer. Possible values are: true to enable double buffering, false to not enable double buffering.

Remarks

When true, the buffer specified with MemoryBufferSize will be multiplied by 2 internally. If MemoryBufferSize is 0 then the default buffer size (64K) will be used internally and then it will be doubled. When false, no double buffering is used. This is the default value.

Note: This member is ignored when using WIA version 2.0.

Example

Refer to WiaSession.AcquireToFile example.
