  +--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.

Constructor Detail

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 painting

anchor - the Rectangle2D in user space used to anchor and replicate the texture

Method Detail

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.

Returns:

the Rectangle2D used to anchor and size this TexturePaint.

createContext

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

userBounds - the user space bounding box of the graphics primitive being rendered

xform - the AffineTransform from user space into device space

hints - a RenderingHints object that can be used to specify how the pattern is ultimately rendered

Returns:

the PaintContext used for generating color patterns.

getTransparency

public int getTransparency()

Returns the transparency mode for this TexturePaint.

Returns:

the transparency mode for this TexturePaint as an integer value.
