Class Figure



  • public class Figure
    extends ObjectWithBounds

    The figure. A container for shapes.

    Code example:

    This examples make use of GraphicsPath and Graphics class to create and manipulate Figures on an Image surface. Example creates a new Image (of type Tiff) and draw paths with the help of GraphicsPath class. At the end DrawPath method exposed by Graphics class is called to render the paths on surface.

    • Constructor Detail

      • Figure

        public Figure()
    • Method Detail

      • getShapes

        public Shape[] getShapes()

        Gets the figure shapes.

        Returns:
        The figure shapes.
      • isClosed

        public boolean isClosed()

        Gets a value indicating whether this figure is closed. A closed figure will make a difference only in case where the first and the last figure's shapes are continuous shapes. In such case the first point of the first shape will be connected by a straight line from the last point of the last shape.

        Returns:
        True if this figure is closed; otherwise, false.
      • setClosed

        public void setClosed(boolean value)

        Sets a value indicating whether this figure is closed. A closed figure will make a difference only in case where the first and the last figure's shapes are continuous shapes. In such case the first point of the first shape will be connected by a straight line from the last point of the last shape.

        Parameters:
        value - True if this figure is closed; otherwise, false.
      • getSegments

        public ShapeSegment[] getSegments()

        Gets the whole figure segments.

        Returns:
        The figure segments.
      • addShape

        public void addShape(Shape shape)

        Adds a shape to the figure.

        Parameters:
        shape - The shape to add.
