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 |

public float getAscent()
ShapeGraphicAttribute
. The
ascent of a ShapeGraphicAttribute
is the positive
distance from the origin of its Shape
to the top of
bounds of its Shape
.

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

public float getAdvance()
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
.

at the specified
location.

in class GraphicAttribute
graphics
- the Graphics2D
into which to render the
graphicx
- the user-space X coordinate where the graphic is renderedy
- the user-space Y coordinate where the graphic is renderedpublic Rectangle2D getBounds()
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.
getBounds
in class GraphicAttribute
Rectangle2D
that encloses all of the bits
rendered by this ShapeGraphicAttribute
.public Shape getOutline(AffineTransform tx)
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
.

- an optional AffineTransform
to apply to the
