Path2Bvr Class

public class Path2Bvr extends Behavior {
    
    // Methods
    public Bbox2Bvr boundingBox(LineStyleBvr style);
    public Path2Bvr close();
    public ImageBvr draw(LineStyleBvr ls);
    public ImageBvr fill(LineStyleBvr ls, ImageBvr im );
    public Path2Bvr transform(Transform2Bvr xf);

    public static Path2Bvr newUninitBvr();

}

Creates an object that represents a path behavior for two-dimensional space. A path behavior consists of a sequence of two-dimensional point behaviors and is typically used to draw images consisting of line segments or to define borders for geometric shapes.

For more information about behaviors, see the Behavior class.

---

boundingBox

Path2Bvr Class

Creates a Path2Bvr object that is a visible bounding box.

public Bbox2Bvr boundingBox(
  LineStyleBvr style
  );

Parameters

style

The LineStyleBvr object that defines the line style of the path. This argument is ignored. The linestyle is always the default linestyle and has a width of 0.

Return Values

Returns the Path2Bvr object.

---

close

Path2Bvr Class

Adds a line segment from the end of the path to the start. This method is useful for animating closed regions.

public Path2Bvr close( );

Return Values

Returns the Path2Bvr object.

---

draw

Path2Bvr Class

Renders the Path2Bvr object into an ImageBvr object. The image is unfilled, which means only the outline is rendered.

public ImageBvr draw(
  LineStyleBvr ls
  );

Parameters

ls

The LineStyleBvr used to render the image.

Return Values

Returns the ImageBvr object.

---

fill

Path2Bvr Class

Renders the Path2Bvr object into an ImageBvr object. The ls argument specifies the LineStyleBvr that is used to draw the outline. The im parameter specifies the image used to fill in the new ImageBvr object.

public ImageBvr fill(
  LineStyleBvr ls,
  ImageBvr im );

Parameters

ls

The LineStyleBvr object used to draw the path.

im

The ImageBvr object used as the fill pattern.

Return Values

Returns the ImageBvr object.

---

transform

Path2Bvr Class

Creates a new path behavior that is the result of applying the given transformation behavior to the points in the original path behavior.

public Path2Bvr transform(
  Transform2Bvr xf
  );

Parameters

a

The Transform2Bvr object representing the transformation to apply to the original path.

Return Values

Returns the Path2Bvr object.

Remarks

This attribute composes values.

---

newUninitBvr

Path2Bvr Class

This method allows you to refer to an Path2Bvr behavior before that behavior has been defined. With this method you can create the behavior and use it in the definition of other behaviors, but not actually define its contents until some later point. (This is accomplished with the init method, which is available on all behaviors.) The system generates a run-time error if you initialize a non-uninitialized behavior, initialize an uninitialized behavior that has already been initialized, or run an initialized behavior that has not yet been initialized.

public static Path2Bvr newUninitBvr( );

Return Values

Returns the Path2Bvr object.
