get_line_approx — Get the current approximation error for contour display.
get_line_approx is obsolete and is only provided for reasons of backward compatibility.
get_line_approx( : : WindowHandle : Approximation)
get_line_approx returns a parameter that controls the approximation error for region contour display in the window. It is used by the operator disp_region. Approximation controls the polygon approximation for contour display ( 0 <=> no approximation). Approximation is only important for displaying the contour of objects, especially if a line style was set with set_line_style.
Window handle.
Current approximation error for contour display.
get_line_approx returns 2 (H_MSG_TRUE) if the window is valid. Otherwise an exception is raised.
