Constructor Detail

LinearGradient

public LinearGradient(double x1,
                      double y1,
                      double x2,
                      double y2)

The x1, x2, y1,y2 attributes of the linearGradient define the start and end position of the gradient

Method Detail

addStop

public void addStop(double index,
                    String color)

Adds the color range for a gradient can be composed of two or more colors. Each color is specified with a offset in order.

setStops

public void setStops(String color1,
                     String color2)

Sets the color range for a gradient can be composed of two colors. It is the same as

 setStops(new Stop(0, color1), new Stop(1, color2));
 

See Also:

setStops(Stop... stops)

setStops

public void setStops(List<Stop> stops)

Sets the color range for a gradient can be composed of two or more colors. Each color is specified with a offset in order.

For example,

 setStops(Arrays.asList(
     new Stop[]{
         new Stop(0, "rgb(255, 255, 255)"),
         new Stop(1, "rgb(200, 200, 255)")
     }
 ));
 

setStops

public void setStops(Stop... stops)

Sets the color range for a gradient can be composed of two or more colors. Each color is specified with a offset in order.

For example,

 setStops(new Stop(0, "rgb(255, 255, 255)"),
          new Stop(1, "rgb(200, 200, 255)"));
 

getStops

public List<Stop> getStops()

Returns the all stops
