Hi list, a bit of squeezed with ps.map : is there a simple way to draw arrowheads on top of vector lines in a map composition ? I did not find any option in vlines instruction. Did I miss it ?
Perhaps should I extract tnodes (or fnodes) from the source lines vector, then print arrowheads as symbols with vpoints instruction. But I can't figure out how I can obtain the angle to rotate symbols the right way, ie finding the azimuth of the last (or first) segment of each line... If anyone experienced this, I would be glad to know how you proceeded. Thank you, Vincent _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
