                       int y2)

annotate

public void annotate(javax.media.opengl.GLAutoDrawable drawable)

Description copied from interface: FrameAnnotater

Each annotator enters annotate with graphics context current, in coordinates with pixel 0,0 in LL corner (note opposite from Java2D) and pixel spacing 1 unit after the scaling transform (which is already active). The FrameAnnotater then can use JOGL calls to render to the screen by getting the GL context, e.g. the following code, used in the context of an AEChip object, draws a golden lines from LL to UR of the pixel array.

        GL gl = drawable.getGL();
        gl.glBegin(GL.GL_LINES);
        gl.glColor3f(.5f, .5f, 0);
        gl.glVertex2f(0, 0);
        gl.glVertex2f(getSizeX() - 1, getSizeY() - 1);
        gl.glEnd();
