LinearGradient Properties

Property Data TypeDescription
startX double X coordinate of the gradient axis start point
startY double Y coordinate of the gradient axis start point
endX double X coordinate of the gradient axis end point
endY double Y coordinate of the gradient axis end point
proportional boolean Whether the coordinates are proportional to the shape that this gradient fills
cycleMethod opaque CycleMethod boolean Cycle method applied to the gradient Whether this paint is completely opaque
stopsList<Stop> Gradient's color specification
