Returns OK.


Sets which contrast value to use.
Scale the values available internally into a homogeneous range between -1000 and 1000. Make sure that a '0' value is available as the Current value when the Source starts up. If the Source's ± range is asymmetric about the '0' value, set range maxima to ±1000 and scale homogeneously from the '0' value in each direction. This will yield a positive range whose step size differs from the negative range's step size.
Plugin uses value -10000 for undefined/default.
