com.eteks.java2d
Class PJAGraphicsEnvironment

java.lang.Object
  java.awt.GraphicsEnvironment
      sun.java2d.SunGraphicsEnvironment
          com.eteks.java2d.PJAGraphicsEnvironment

All Implemented Interfaces:: sun.java2d.FontSupport

public class PJAGraphicsEnvironment
extends sun.java2d.SunGraphicsEnvironment

Pure Java AWT GraphicsEnvironment implementation. This implementation enables to get an environment even when no Display is available.
java.awt.graphicsenv system property have to be set to com.eteks.java2d.PJAGraphicsEnvironment to allow the change of java.awt.GraphicsEnvironment default implementation. java.awt.fonts system property must be set to the path where True Type fonts files will be loaded from (this property must be defined to avoid calling the getFontPath () native method of the class NativeFontWrapper which needs a X11 Display in Motif implementation).
This path can be equal to :

/usr/openwin/lib/X11/fonts/Type1:/usr/openwin/lib/X11/fonts/TrueType directories on Solaris
WinDir\Font directory on Windows
($JAVAHOME)/lib/fonts
Any directory list containing True Type fonts

Java2D can work with PJA only with JVM version >= 1.2. When GraphicsEnvironment.getLocalGraphicsEnvironment () fails because PJAGraphicsEnvironment class can't be loaded or java.awt.graphicsenv system property can't be changed, java.awt.Font can't be instantiated without a Display since this class requires an instance of java.awt.GraphicsEnvironment in Java 1.2. In that case, it forbids to use Graphics2D methods in a program because Graphics2D needs a default font (see PJADemo.java source for a way to change of .pjaf font).
