protected GraphicAttribute(int alignment)
GraphicAttribute
.
Subclasses use this to define the alignment of the graphic.
alignment
- an int representing one of the
GraphicAttribute
alignment fields
IllegalArgumentException
- if alignment is not one of the
five defined values.Method Detail |

public abstract float getAscent()
GraphicAttribute
. A
graphic can be rendered above its ascent.
GraphicAttribute
.getBounds()
public abstract float getDescent()
GraphicAttribute
. A
graphic can be rendered below its descent.
GraphicAttribute
.getBounds()
public abstract float getAdvance()
GraphicAttribute
. The
GraphicAttribute
object's advance is the distance
from the point at which the graphic is rendered and the point where
the next character or graphic is rendered. A graphic can be
rendered beyond its advance
GraphicAttribute
.getBounds()
public Rectangle2D getBounds()
Rectangle2D
that encloses all of the
bits drawn by this GraphicAttribute
relative to the
rendering position.
A graphic may be rendered beyond its origin, ascent, descent,
or advance; but if it is, this method's implementation must
indicate where the graphic is rendered.
Default bounds is the rectangle (0, -ascent, advance, ascent+descent).
Rectangle2D
that encloses all of the bits
rendered by this GraphicAttribute
.public Shape getOutline(AffineTransform tx)
Shape
that represents the region that
this GraphicAttribute
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
.
The default implementation returns the rectangle returned by
getBounds()
, transformed by the provided AffineTransform
if present.
tx
- an optional AffineTransform
to apply to the
outline of this GraphicAttribute
. This can be null.
Shape
representing this graphic attribute,
suitable for stroking or filling.public abstract void draw(Graphics2D graphics, float x, float y)
GraphicAttribute
at the specified
location.
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 final int getAlignment()
GraphicAttribute
.
Alignment can be to a particular baseline, or to the absolute top
or bottom of a line.
GraphicAttribute
.public GlyphJustificationInfo getJustificationInfo()
GraphicAttribute
. Subclasses
can override this method to provide different justification
information.
GlyphJustificationInfo
object that contains the
justification information for this GraphicAttribute
.
