Device Class

Gets or sets the compression used during a file or memory transfer.

Gets a value indicating if the source will allow you to display the source interface without acquiring an image.

If the device does support this feature, you can use the ShowUserInterface method to display the device interface and allow the user to select their options without acquiring an image.

Gets or sets the exposure time used to capture the image in seconds.

Gets or sets the file format used when saving the acquired image directly to a file.

Gets the FileSystem for the device if supported.

The FileSystem is used for navigating through the folders and files of some cameras and scanners.

Gets or sets the rectangular area of the scanning bed to acquire.

If you know ahead of time the location and size of the object to scan, and the device supports this feature, you can decrease the amount of scanning time by setting this property.

Gets or sets the static frame size for the acquire.

Gets the number of available images.

This is only valid for devices which contain an internal buffer. You can find out if there are any pending images during an acquisition by checking the PendingImages property of the AcquireEventArgs class.

Gets or sets the pixel format to acquire.

You should set this property before setting BitDepth.

Gets or sets the zoom factor to use for the acquire.

Valid values for this property are source defined.

This method may be removed in a future version. New applications should use the TryOpen method instead.

Returns a value indicating whether or not the Open method can currently be used on the device.

This lets you choose how the device should handle its buffer clearing procedure.

Closes the connection with the device previously opened.

Calling this method when an image is being acquired will cancel the acquisition and any pending transfers. If you want to close the connection after all images have been transferred, you should do so in the AcquireFinished event.

Opens a connection to this device.

You must open a connection to the device before getting or setting any device properties. If you don't need to get or set any properties, you can call the Acquire method without using the Open or Close methods.

TryOpen is the preferred way to open a connection to the device.

Determines if a capability is available from the device.

It's unlikely that any one device supports all of the properties and features. You can use this method to find out if a property is get-able and/or set-able. This can also be used to help determine if the device is a camera by checking for camera specific properties, such as FlashUsed or BatteryPercentage.

Sets the indices of the images you want to acquire.

This is useful when you want to acquire multiple images from a camera with a single call to the Acquire method.

Displays the device interface.

This operation is used by applications that wish to display the device user interface to allow the user to manipulate the devices current settings for resolution, paper size, etc. but not acquire an image.

Starts an automatic capture process.

This method does not acquire the images. Automatic capture implies that the device is capable of capturing images without the presence of the Application. This means that it must be possible for the Application to close the device and reopen it later, after the images have been captured.

This method will attempt to open a connection to the device and will return true if it was successful. It's preferred to use this method instead of the Open method.

The Close method must be called when you are finished using the device.
