RadialGradient Properties

Property Data Type Description
focusAngle double Angle in degrees from the center of the gradient to the focus point to which the first color is mapped
focusDistancedouble Distance from the center of the gradient to the focus point to which the first color is mapped
centerX double X coordinate of the center point of the gradient's circle
centerY double Y coordinate of the center point of the gradient's circle
Radius double Radius of the circle defining the extents of the color gradient
Proportional boolean Coordinates and sizes are proportional to the shape that this gradient fills
cycleMethod CycleMethod Cycle method applied to the gradient
opaque stops boolean List<Stop> Whether the paint is completely opaque Gradient's color specification
