Class PatternFactory

java.lang.Object

gov.nasa.worldwind.render.PatternFactory

public class PatternFactory
extends java.lang.Object

Static class to creates tilable patterns.

The createPattern() method draws a shape inside a usually square bitmap, so that it will match if tiled.

Each pattern supports a scale factor between zero and one - default is .5. With a scale of zero no pattern will be produced. With a scale of one the pattern will cover all the background.
