v.gradient Output a stream with a grayscale gradient. Output a stream with a grayscale gradient. v.gradient creates a gradient across the image plane. This gradient is fully variable in angle, slope and center value. If the component size is int8, the output is centered on 128 and ranges from 0 to 255. If the component size is int16, the output is centered on 0 and ranges from -32768 to 32767. v.gradient can operate as a source. You can start it sending a stream by sending a 1 into its first inlet. You can stop it by sending a 0. You can synchronize it to another video stream by connecting the video stream to the first inlet.
