Constructor	Description
TilingPaint(PageDrawer drawer, PDTilingPattern pattern, AffineTransform xform)	Creates a new colored tiling Paint, i.e.
TilingPaint(PageDrawer drawer, PDTilingPattern pattern, PDColorSpace colorSpace, PDColor color, AffineTransform xform)	Creates a new tiling Paint.

Method Summary

Modifier and Type	Method	Description
private static int	ceiling(double num)	Returns the closest integer which is larger than the given number.
PaintContext	createContext(ColorModel cm, Rectangle deviceBounds, Rectangle2D userBounds, AffineTransform xform, RenderingHints hints)	Not called in TexturePaint subclasses, which is why we wrap TexturePaint.
private Rectangle2D	getAnchorRect(PDTilingPattern pattern)	Returns the anchor rectangle, which includes the XStep/YStep and scaling.
private BufferedImage	getImage(PageDrawer drawer, PDTilingPattern pattern, PDColorSpace colorSpace, PDColor color, AffineTransform xform, Rectangle2D anchorRect)	Returns the pattern image in parent stream coordinates.

Constructor Details

TilingPaint

TilingPaint(PageDrawer drawer,
 PDTilingPattern pattern,
 AffineTransform xform)
     throws IOException

Creates a new colored tiling Paint, i.e. one that has its own colors.

Parameters:

drawer - renderer to render the page

pattern - tiling pattern dictionary

xform - device scale transform

Throws:

IOException - if something goes wrong while drawing the pattern

TilingPaint

TilingPaint(PageDrawer drawer,
 PDTilingPattern pattern,
 PDColorSpace colorSpace,
 PDColor color,
 AffineTransform xform)
     throws IOException

Creates a new tiling Paint. The parameters color and colorSpace must be null for a colored tiling Paint (because it has its own colors), and non null for an uncolored tiling Paint.

Parameters:

drawer - renderer to render the page

pattern - tiling pattern dictionary

colorSpace - color space for this tiling

color - color for this tiling

xform - device scale transform

Throws:

IOException - if something goes wrong while drawing the pattern

Method Details

createContext

public PaintContext createContext(ColorModel cm,
 Rectangle deviceBounds,
 Rectangle2D userBounds,
 AffineTransform xform,
 RenderingHints hints)

Not called in TexturePaint subclasses, which is why we wrap TexturePaint.

Specified by:

createContext in interface Paint

getImage

private BufferedImage getImage(PageDrawer drawer,
 PDTilingPattern pattern,
 PDColorSpace colorSpace,
 PDColor color,
 AffineTransform xform,
 Rectangle2D anchorRect)
                        throws IOException

Returns the pattern image in parent stream coordinates.

Throws:

IOException

ceiling

private static int ceiling(double num)

Returns the closest integer which is larger than the given number. Uses BigDecimal to avoid floating point error which would cause gaps in the tiling.

getTransparency

public int getTransparency()

Specified by:

getTransparency in interface Transparency

getAnchorRect

private Rectangle2D getAnchorRect(PDTilingPattern pattern)
                           throws IOException

Returns the anchor rectangle, which includes the XStep/YStep and scaling.

Throws:

IOException
