These settings are intended to boost the performance of a Source. The fundamental assumption
behind AutomaticScanning is that the device is able to capture the number of images indicated by the value
of CAP_XFERCOUNT without waiting for the Application to request the image transfers.This is
only possible if the device has internal buffers capable of caching the images it captures.

Syntax
The AutomaticScanning type exposes the following members.
Methods
| Name | Description | |
|---|---|---|
 | Equals | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
 | Finalize | Allows an Object to attempt to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.) |
| GetCapabilities | (Inherited from CapSetBase.) |
| GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
| GetType | Gets the Type of the current instance. (Inherited from Object.) |
| MakeCapT | (Inherited from CapSetBase.) |
| MakeCapArrT | (Inherited from CapSetBase.) |
| MakeCapReadOnlyT | (Inherited from CapSetBase.) |
| MakeCapReadOnlyArrayT | (Inherited from CapSetBase.) |
| MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
| ToString | Returns a String that represents the current Object. (Inherited from Object.) |
Properties
| Name | Description | |
|---|---|---|
 | AutoScan |
Enables the source’s automatic document scanning process.
CAP_AUTOSCAN
|
| CameraEnabled |
When set to true the device will deliver images from the current camera.
CAP_CAMERAENABLED
|
| CameraOrder |
This capability selects the order of output for Single Document Multiple Image (SDMI) mode
based on an array of pixel types; it does not constrain the allowed pixel types.
CAP_CAMERAORDER
|
| CameraSide |
TWAIN models a duplex scanner as conceptually having two 'cameras' - a 'top' camera that
captures the front of each page, and a 'bottom' camera that captures the back.
|
| ClearBuffers |
Getting Value reports the presence of data in the scanner’s buffers. Setting with a value of
TwCB.Clear immediately clears the buffers.
CAP_CAMERASIDE
|
| MaxBatchBuffers | .
Describes the number of pages that the scanner can buffer.
CAP_MAXBATCHBUFFERS
