public Class PixelToParallelogramConverter

extends PixelToShapeConverter
implements ShapeDrawPipe
Class Inheritance
All Implemented Interfaces
sun.java2d.pipe.ShapeDrawPipe
Known Direct Subclasses
sun.java2d.SurfaceData.PixelToPgramLoopConverter
Imports
java.awt.Shape, .BasicStroke, java.awt.geom.Line2D, .Rectangle2D, .AffineTransform, sun.java2d.SunGraphics2D, sun.awt.SunHints
This class converts calls to the basic pixel rendering methods into calls to the methods on a ParallelogramPipe. Most calls are transformed into calls to the fill(Shape) method by the parent PixelToShapeConverter class, but some calls are transformed into calls to fill/drawParallelogram().

Overrides sun.java2d.pipe.PixelToShapeConverter.drawRect.

Implements sun.java2d.pipe.PixelDrawPipe.drawRect.

public void
drawRectangle(SunGraphics2D sg2d, double rx, double ry, double rw, double rh, double lw)

public void
fill(SunGraphics2D sg2d, Shape s)

Implements sun.java2d.pipe.ShapeDrawPipe.fill.

This utility function handles the case where a drawRectangle operation discovered that the interior hole in the rectangle or parallelogram has been completely filled in by the stroke width. It calculates the outer parallelogram of the stroke and issues a single fillParallelogram request to fill it.
