Class NonlinearColorScale

java.lang.Object

com.hfg.graphics.NonlinearColorScale

All Implemented Interfaces:

ColorRule, Comparable

public class NonlinearColorScale
extends Object
implements ColorRule, Comparable

Non-linear Color scale created from three or more colors.

Ex:

 OrderedMap<Float, Color> colorMap = new OrderedMap<>(3);
 colorMap.put(20f,Color.GREEN);
 colorMap.put(80f,Color.YELLOW);
 colorMap.put(200f,Color.RED);

 NonlinearColorScale colorScale =new NonlinearColorScale(colorMap);

 center.br(4);
 center.addSpan("Non-linear Color Scale Created from Green (20), Yellow (80), & Red (200)");
 Table table = center.addTable();
 Tr row = table.addRow();

 for (int i = 20; i <=200; i+=20)
 {
   HTMLColor scaleColor = new HTMLColor(colorScale.assignColorForValue(i));
   row.addCell(String.format("%d", i))
       .setStyle(CSS.color(scaleColor.getContrastingColor()) + CSS.bgColor(scaleColor));
 }
