Method Detail

viewLegend

void viewLegend(IDrawing drw)

This method will be called when the Open GL context has been set and the matrix mode has been set to GL_PROJECTION. That is, this method is used to draw objects in the screen (or instrument) co-ordinates. The projection matrix is set so that the screen area has the co-ordinate space (0.0, 0.0) to (1.0, 1.0), thus the point (0.5, 0.5) will be in the centre of the screen. This mode of drawing is intended for drawing a map legend.
