Hello, i currently try to make the little points in an "intermittent waterflow" more visible on clay background. For this i tried to make the points bigger and added to my layout section: ---------------- layout hvho_basic.layout # more irrelevant stuff here... symbol-set AUT # Thicker lines for water flow in default symbol; note that AUT does not define l_waterflow_conjectural code metapost def l_waterflow_conjectural_SKBB (expr Path) = %thdrawoptions(dashed withdots scaled (0.9 * optical_zoom) withpen PenB); l_waterflow_permanent_UIS (Path); %thdrawoptions(); enddef; endcode # more irrelevant stuff here ---------------- However, this does yield nothing. I even (see above example) removed the thdraw commands so it should print a straight line, but it still is pointy. Whateer i do, i cannot bring this to work. What am i overlooking here? With best regards, Beni
