}
Property Value
Type:
ByteThe preview bitmap image.
Remarks 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.
Examples 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);
}
Using memStr = New MemoryStream(frame.PreviewBitmap)
bmp = DirectCast(Image.FromStream(memStr), Bitmap)
End Using
