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.
