When I try to call renderer.takeSnapshot from inside a SimpleCanvasImpl, I am getting the following exception.
Exception in thread "main" java.lang.NullPointerException
at org.lwjgl.opengl.GL11.glReadPixels(GL11.java:2337)
at com.jme.renderer.lwjgl.LWJGLRenderer.grabScreenContents(Unknown Source)
at com.jme.renderer.lwjgl.LWJGLRenderer.takeScreenShot(Unknown Source)
Has anyone else run into this? I looked at the source for GL11 and it's an interface. Before I go and reverse engineer the code, does anyone have any helpful hints?
thanks.
