com.reportmill.graphics.RMFill

com.reportmill.graphics.RMContourFill

All Implemented Interfaces:

java.awt.Paint, java.awt.PaintContext, java.awt.Transparency

public class RMContourFill
extends RMFill
implements java.awt.PaintContext, java.awt.Paint

RMFill implementation of a shape-burst gradient. Implements Paint & PaintContext methods for scan converting the gradient into an ARGB raster. Can be used on its own for a vaguely-interesting fill, or to create a bump map for the emboss effect. Currently the edge profile is a 45 degree straight line, but other edge profiles (rounded, cove, whatever) can easily be added.

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

Paint & PaintContext interfaces.

Specified by:

createContext in interface java.awt.Paint

getRaster

public java.awt.image.Raster getRaster(int x,
                                       int y,
                                       int w,
                                       int h)

Creates a new raster.

Specified by:

getRaster in interface java.awt.PaintContext

doShading

public void doShading(int[] samples,
                      int offset,
                      int devicex,
                      int devicey,
                      int w,
                      int h,
                      int rowbytes)

Replaces image samples with distance from pixel scaled to the range [0-1]. We scale every distance by the maximum. This means that the color of each edge will change with the same slope, and thicker sections will therefore be taller (if edge color is thought of as height). Another possibility would be to scale each edge by its local max, so each section ultimately reaches same height.
