Class TexturePaint
java.lang.Object
|
+--java.awt.TexturePaint
- public class TexturePaint
- extends Object
- implements Paint
The TexturePaint
class provides a way to fill a
Shape
with a texture that is specified as
a BufferedImage
. The size of the BufferedImage
object should be small because the BufferedImage
data
is copied by the TexturePaint
object.
At construction time, the texture is anchored to the upper
left corner of a Rectangle2D
that is
specified in user space. Texture is computed for
locations in the device space by conceptually replicating the
specified Rectangle2D
infinitely in all directions
in user space and mapping the BufferedImage
to each
replicated Rectangle2D
.

TexturePaint
public TexturePaint(java.awt.image.BufferedImage txtr,
java.awt.geom.Rectangle2D anchor)
- Constructs a
TexturePaint
object.
- Parameters:
txtr
- the BufferedImage
object with the texture
used for paintinganchor
- the Rectangle2D
in user space used to
anchor and replicate the texture
getImage
public java.awt.image.BufferedImage getImage()
- Returns the
BufferedImage
texture used to
fill the shapes.
- Returns:
- a
BufferedImage
.
getAnchorRect
public java.awt.geom.Rectangle2D getAnchorRect()
- Returns a copy of the anchor rectangle which positions and
sizes the textured image.

createContext
public PaintContext createContext(java.awt.image.ColorModel cm,
Rectangle deviceBounds,
java.awt.geom.Rectangle2D userBounds,

RenderingHints hints)
- Creates and returns a context used to generate the color pattern.
- Specified by:
- createContext in interface Paint
- Parameters:
cm
- the ColorModel
that receives the
Paint
data. This is used only as a hint.deviceBounds
- the device space bounding box of the graphics
primitive being rendereduserBounds
- the user space bounding box of the graphics
primitive being renderedxform
- the AffineTransform
from user space
into device spacehints
- a RenderingHints
object that can be used to
specify how the pattern is ultimately rendered- Returns:
- the
PaintContext
used for generating color
patterns. - See Also:
