 java.awt.font.GraphicAttribute
All known Subclasses: java.awt.font.ImageGraphicAttribute, java.awt.font.ShapeGraphicAttribute,
| GraphicAttribute | | abstract public class GraphicAttribute (Code) | | This class is used with the CHAR_REPLACEMENT attribute.
The GraphicAttribute class represents a graphic embedded
in text. Clients subclass this class to implement their own char
replacement graphics. Clients wishing to embed shapes and images in
text need not subclass this class. Instead, clients can use the
ShapeGraphicAttribute and
ImageGraphicAttribute
classes.
Subclasses must ensure that their objects are immutable once they
are constructed. Mutating a GraphicAttribute that
is used in a
TextLayout results in undefined behavior from the
TextLayout.

| Field Summary | |
| final public static int | BOTTOM_ALIGNMENT
Aligns bottom of graphic to bottom of line. | | final public static int | CENTER_BASELINE
Aligns origin of graphic to center baseline of line. | | final public static int | HANGING_BASELINE
Aligns origin of graphic to hanging baseline of line. | | final public static int | ROMAN_BASELINE
Aligns origin of graphic to roman baseline of line. | | final public static int | TOP_ALIGNMENT
Aligns top of graphic to top of line. |
| Constructor Summary | |
| protected | GraphicAttribute(int alignment)
Constructs a GraphicAttribute. |
| BOTTOM_ALIGNMENT | | final public static int BOTTOM_ALIGNMENT(Code) | | Aligns bottom of graphic to bottom of line.
|
| CENTER_BASELINE | | final public static int CENTER_BASELINE(Code) | | Aligns origin of graphic to center baseline of line.
|
| HANGING_BASELINE | | final public static int HANGING_BASELINE(Code) | | Aligns origin of graphic to hanging baseline of line.
|
| ROMAN_BASELINE | | final public static int ROMAN_BASELINE(Code) | | Aligns origin of graphic to roman baseline of line.
|
| TOP_ALIGNMENT | | final public static int TOP_ALIGNMENT(Code) | | Aligns top of graphic to top of line.
|
| GraphicAttribute | | protected GraphicAttribute(int alignment)(Code) | | Constructs a GraphicAttribute.
Subclasses use this to define the alignment of the graphic.
Parameters:
alignment - an int representing one of the GraphicAttribute alignment fields
throws:
IllegalArgumentException - if alignment is not one of thefive defined values. |
| draw | | abstract public void draw(Graphics2D graphics, float x, float y)(Code) | | Renders this GraphicAttribute at the specified
location.
Parameters:
graphics - the Graphics2D into which to render thegraphic
Parameters:
x - the user-space X coordinate where the graphic is rendered
Parameters:
y - the user-space Y coordinate where the graphic is rendered |
| getAdvance | | abstract public float getAdvance()(Code) | | Returns the advance of this 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
the advance of this GraphicAttribute.
See Also: GraphicAttribute.getBounds() |
| getAlignment | | final public int getAlignment()(Code) | | Returns the alignment of this GraphicAttribute.
Alignment can be to a particular baseline, or to the absolute top
or bottom of a line.
the alignment of this GraphicAttribute. |
| getAscent | | abstract public float getAscent()(Code) | | Returns the ascent of this GraphicAttribute. A
graphic can be rendered above its ascent.
the ascent of this GraphicAttribute.
See Also: GraphicAttribute.getBounds() |
| getBounds | | public Rectangle2D getBounds()(Code) | | Returns a
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).
a Rectangle2D that encloses all of the bitsrendered by this GraphicAttribute. |
| getDescent | | abstract public float getDescent()(Code) | | Returns the descent of this GraphicAttribute. A
graphic can be rendered below its descent.
the descent of this GraphicAttribute.
See Also: GraphicAttribute.getBounds() |
| getJustificationInfo | | public GlyphJustificationInfo getJustificationInfo()(Code) | | Returns the justification information for this
GraphicAttribute. Subclasses
can override this method to provide different justification
information.
a GlyphJustificationInfo object that contains thejustification information for this GraphicAttribute. |
| getOutline | | public Shape getOutline(AffineTransform tx)(Code) | | Return a
java.awt.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
GraphicAttribute.getBounds , transformed by the provided
AffineTransform if present.
Parameters:
tx - an optional AffineTransform to apply to theoutline of this GraphicAttribute. This can be null. a Shape representing this graphic attribute,suitable for stroking or filling.
