IVideoFramePreviewBitmap Property

Returns a preview bitmap for the last video frame as an array of byte.

Namespace:  ASCOM.DeviceInterface
Assembly:  ASCOM.DeviceInterfaces (in ASCOM.DeviceInterfaces.dll) Version: 3c9121baba46811fe6e53a58a05935662261416d
byte[] PreviewBitmap { get; }

Property Value

Type: Byte
The preview bitmap image.

Must be implemented, must not throw an ASCOM.PropertyNotImplementedException.

The application can use this bitmap to show a preview image of the last video frame when required. This is a convenience property for those applications that don't require to process the ImageArray but usually only adjust the video camera settings and then record a video file.

When a 24bit RGB image can be returned by the driver this should be the preferred format.

The following code can be used to create a Bitmap from the returned byte array
using (var memStr = new MemoryStream(frame.PreviewBitmap))
bmp = (Bitmap)Image.FromStream(memStr);
