This component is obsolete and its use in filters is not recommended. Use the recent version of the component.
The Gaussian component generates a gaussian curve (also known as 'bell curve'). This is a curve component, it can be located in the Curves category on the Components Bar.
Width: Map Input
Defines the width of the curve. Lower values make the curve thinner, higher values make it wider. Since Width is a map input, its value can be controlled separately for different image areas by connecting a map component to this input.
Minimum and Maximum: Map Inputs
Minimum and Maximum define the output range of the curve. When the Minimum value is greater than the Maximum value, they get reversed – the Minimum parameter defines the Maximum value and vice versa. This is needed to avoid turning the curve upside down. Since Minimum and Maximum are map inputs, their values can be controlled separately for different image areas by connecting a map component to any of these inputs.
Inverts the curve, converting its value at each point to its opposite: 0.05 to 0.95, 0.25 to 0.75 etc. Invert is applied to the curve before Minimum and Maximum take effect, so they still define the output range correctly.
