MetaPost drawarrow dashed evenly
Hello, How does one draw a dashed arrow (without getting a dashed arrowhead)? Minimal example: \startMPpage drawarrow origin--(1cm,1cm) ; drawarrow origin--(-1cm,1cm) dashed evenly ; \stopMPpage Is this a bug? Alan

To be complete I've added an undashed operator: \startMPpage drawarrow origin--(1cm, 1cm) dashed evenly withcolor red undashed ; drawarrow origin--(1cm,-1cm) dashed evenly withcolor blue ; \stopMPpage ----------------------------------------------------------------- Hans Hagen | PRAGMA ADE Ridderstraat 27 | 8061 GH Hasselt | The Netherlands tel: 038 477 53 69 | voip: 087 875 68 74 | www.pragma-ade.com | www.pragma-pod.nl -----------------------------------------------------------------
