      com.jmex.bui.text.AWTTextFactory

All Implemented Interfaces:

BConstants

public class AWTTextFactory
extends BTextFactory

Formats text by using the AWT to render runs of text into a bitmap and then texturing a quad with the result. This text factory handles a simple styled text syntax:

 @=b(this text would be bold)
 @=i(this text would be italic)
 @=s(this text would be striked-through)
 @=u(this text would be underlined)
 @=bi(this text would be bold and italic)
 @=bi#FFCC99(this text would be bold, italic and pink)
