Constructor Detail

• ShapeGraphicAttribute

  public ShapeGraphicAttribute(Shape shape,
                               int alignment,
                               boolean stroke)

  Constructs a ShapeGraphicAttribute for the specified Shape.

  Parameters:

  shape - the Shape to render. The Shape is rendered with its origin at the origin of this ShapeGraphicAttribute in the host TextLayout. This object maintains a reference to shape.

  alignment - one of the alignments from this ShapeGraphicAttribute.

  stroke - true if the Shape should be stroked; false if the Shape should be filled.

Method Detail

• getAscent

  public float getAscent()

  Returns the ascent of this ShapeGraphicAttribute. The ascent of a ShapeGraphicAttribute is the positive distance from the origin of its Shape to the top of bounds of its Shape.

  Specified by:

  getAscent in class GraphicAttribute

  Returns:

  the ascent of this ShapeGraphicAttribute.

  See Also:

  GraphicAttribute.getBounds()

• getDescent

  public float getDescent()

  Returns the descent of this ShapeGraphicAttribute. The descent of a ShapeGraphicAttribute is the distance from the origin of its Shape to the bottom of the bounds of its Shape.

  Specified by:

  getDescent in class GraphicAttribute

  Returns:

  the descent of this ShapeGraphicAttribute.

  See Also:

  GraphicAttribute.getBounds()

• getAdvance

  public float getAdvance()

  Returns the advance of this ShapeGraphicAttribute. The advance of a ShapeGraphicAttribute is the distance from the origin of its Shape to the right side of the bounds of its Shape.

  Specified by:

  getAdvance in class GraphicAttribute

  Returns:

  the advance of this ShapeGraphicAttribute.

  See Also:

  GraphicAttribute.getBounds()

• draw

  public void draw(Graphics2D graphics,
                   float x,
                   float y)

  Renders this GraphicAttribute at the specified location.

  Specified by:

  draw in class GraphicAttribute

  Parameters:

  graphics - the Graphics2D into which to render the graphic

  x - the user-space X coordinate where the graphic is rendered

  y - the user-space Y coordinate where the graphic is rendered

• getBounds

  public Rectangle2D getBounds()

  Returns a Rectangle2D that encloses all of the bits drawn by this ShapeGraphicAttribute relative to the rendering position. A graphic can be rendered beyond its origin, ascent, descent, or advance; but if it does, this method's implementation should indicate where the graphic is rendered.

  Overrides:

  getBounds in class GraphicAttribute

  Returns:

  a Rectangle2D that encloses all of the bits rendered by this ShapeGraphicAttribute.

• getOutline

  public Shape getOutline(AffineTransform tx)

  Return a Shape that represents the region that this ShapeGraphicAttribute renders. This is used when a TextLayout is requested to return the outline of the text. The (untransformed) shape must not extend outside the rectangular bounds returned by getBounds.

  Overrides:

  getOutline in class GraphicAttribute

  Parameters:

  tx - an optional AffineTransform to apply to the this ShapeGraphicAttribute. This can be null.

  Returns:

  the Shape representing this graphic attribute, suitable for stroking or filling.

  Since:

  1.6

• hashCode

  public int hashCode()

  Returns a hashcode for this ShapeGraphicAttribute.

  Overrides:

  hashCode in class Object

  Returns:

  a hash code value for this ShapeGraphicAttribute.

  See Also:

  Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)

• equals

  public boolean equals(Object rhs)

  Compares this ShapeGraphicAttribute to the specified Object.

  Overrides:

  equals in class Object

  Parameters:

  rhs - the Object to compare for equality

  Returns:

  true if this ShapeGraphicAttribute equals rhs; false otherwise.

  See Also:

  Object.hashCode(), HashMap

• equals

  public boolean equals(ShapeGraphicAttribute rhs)

  Compares this ShapeGraphicAttribute to the specified ShapeGraphicAttribute.

  Parameters:

  rhs - the ShapeGraphicAttribute to compare for equality

  Returns:

  true if this ShapeGraphicAttribute equals rhs; false otherwise.
