public class PolygonBackground
extends Background

Paints a filled polygon as a background in a specific color.

usage:

 .myItem {
                background {    
                        type: polygon;
                        color: green;
                        points: 0,50 50,0 100,50 50,100;
                        max-x: 100; 
                        max-y: 100;
                        scale-mode: proportional; // none, scale, proportional, expand 
                        expand: false;
                }

Field Summary

static int	MODE_NO_SCALE use this mode for not scaling the polygon at all
static int	MODE_SCALE use this mode for scaling the polygon according to the width and height of the background - the given reference width and height are used for calculating the actual positions
static int	MODE_SCALE_PROPORTIONAL use this mode for scaling the polygon proportional according to the minimum of width and height of the background - the given reference width and height are used for calculating the actual positions
static int	MODE_SCALE_PROPORTIONAL_EXPAND use this mode for scaling the polygon proportional according to the maximum of width and height of the background - the given reference width and height are used for calculating the actual positions

Constructor Detail

PolygonBackground

public PolygonBackground(int color,
                         Point[] points,
                         int referenceWidth,
                         int referenceHeight,
                         int scalingMode,
                         int anchor)

Creates a new simple background.

Parameters:

color - the color of the background in RGB, e.g. 0xFFDD11

points - the points of the polygon

referenceWidth - the maximum horizontal position, 0 when the positions should not be scaled

referenceHeight - the maximum horizontal position, 0 when the positions should not be scaled

scalingMode - the scaling mode to be used

anchor - the anchor like Graphics.TOP | Graphics.RIGHT etc - only applicable in no-expanded proportional or non-scaling mode
