Parameters

focus

A value from 0 through 1 that specifies the center of the gradient (the point where the gradient is composed of only the ending color).

scale

A value from 0 through1 that specifies how fast the colors falloff from the starting color to focus (ending color)

Remarks

This method specifies a focus, which is the point where the gradient is composed only of the ending color. The focus parameter represents a location as a proportion of the distance along the gradient line. The gradient falls off to the starting color linearly to either side.
