Class RadialGradient

public RadialGradient(double focusAngle, double focusDistance, double centerX, double centerY, double radius, boolean proportional, CycleMethod cycleMethod, Stop... stops)

Creates a new instance of RadialGradient.

public RadialGradient(double focusAngle, double focusDistance, double centerX, double centerY, double radius, boolean proportional, CycleMethod cycleMethod, List<Stop> stops)

Creates a new instance of RadialGradient.

public final double getFocusAngle()

Defines the angle in degrees from the center of the gradient to the focus point to which the first color is mapped.

public final double getFocusDistance()

Defines the distance from the center of the gradient to the focus point to which the first color is mapped. A distance of 0.0 will be at the center of the gradient circle. A distance of 1.0 will be on the circumference of the gradient circle.

public final double getCenterX()

Defines the X coordinate of the center point of the circle defining the gradient. If proportional is true (the default), this value specifies a point on a unit square that will be scaled to match the size of the the shape that the gradient fills. The last color of the gradient is mapped to the perimeter of this circle.

public final double getCenterY()

Defines the X coordinate of the center point of the circle defining the gradient. If proportional is true (the default), this value specifies a point on a unit square that will be scaled to match the size of the the shape that the gradient fills. The last color of the gradient is mapped to the perimeter of this circle.

public final double getRadius()

Specifies the radius of the circle defining the extents of the color gradient. If proportional is true (the default), this value specifies a size relative to unit square that will be scaled to match the size of the the shape that the gradient fills.

public final boolean isProportional()

Indicates whether the center and radius values are proportional or absolute. If this flag is true, the center point and radius are defined in a coordinate space where coordinates in the range [0..1] are scaled to map onto the bounds of the shape that the gradient fills. If this flag is false, then the center coordinates and the radius are specified in the local coordinate system of the node.

public final CycleMethod getCycleMethod()

Defines the cycle method applied to the RadialGradient. One of: CycleMethod.NO_CYCLE, CycleMethod.REFLECT, or CycleMethod.REPEAT.

public final List<Stop> getStops()

A sequence of 2 or more Stop values specifying how to distribute the colors along the gradient. These values must be in the range 0.0 to 1.0. They act like keyframes along the gradient: they mark where the gradient should be exactly a particular color.

Each stop in the sequence must have an offset that is greater than the previous stop in the sequence.

The list is unmodifiable and will throw UnsupportedOperationException on each modification attempt.

public final boolean isOpaque()

Gets whether this Paint is completely opaque. An opaque paint is one that has no alpha component in any of its colors. It may be possible for a Paint to be opaque and yet return false, if it cannot be easily determined whether the paint is actually opaque. For example, the ImagePattern may not be able to cheaply determine its opacity.

public boolean equals(Object obj)

Indicates whether some other object is "equal to" this one.

public int hashCode()

Returns a hash code for this RadialGradient object.

public String toString()

Returns a string representation of this RadialGradient object.

public static RadialGradient valueOf(String value)

Creates a radial gradient value from a string representation.

The format of the string representation is based on JavaFX CSS specification for radial gradient which is

 radial-gradient([focus-angle <angle>, ]?
                 [focus-distance <percentage>, ]?
                 [center <point>, ]?
                 radius [<length> | <percentage>],
                 [[repeat | reflect],]?
                 <color-stop>[, <color-stop>]+)
 

where

 <point> = [ [ <length> <length> ] | [ <percentage> | <percentage> ] ]
 <color-stop> = [ <color> [ <percentage> | <length>]? ]
 

Currently length can be only specified in px, the specification of unit can be omited. Format of color representation is the one used in Color.web(String color). The radial-gradient keyword can be omited. For additional information about the format of string representation, see the CSS Reference Guide.

Examples:

 RadialGradient g
      = RadialGradient.valueOf("radial-gradient(center 100px 100px, radius 200px, red  0%, blue 30%, black 100%)");
 RadialGradient g
      = RadialGradient.valueOf("center 100px 100px, radius 200px, red  0%, blue 30%, black 100%");
 RadialGradient g
      = RadialGradient.valueOf("radial-gradient(center 50% 50%, radius 50%,  cyan, violet 75%, magenta)");
 RadialGradient g
      = RadialGradient.valueOf("center 50% 50%, radius 50%,  cyan, violet 75%, magenta");
