This is my overloaded symbol for gradient point. I want to make a line symbol for gradient but I havent gotten around to it. code metapost def p_gradient_AMER (expr pos,theta,sc,al) = U:=(.15u, .4u); T:=identity aligned al rotated theta scaled sc shifted pos; pickup PenC; #Left Hand side thdraw (-.3u, -.2u) -- (-.7u, .1u); thdraw (-.2u, -.1u) -- (-.4u, .6u); #Centerline thdraw (0u, 0u) -- (0u, .9u); #Right side thdraw (.3u, -.2u) -- (.7u, .1u); thdraw (.2u, -.1u) -- (.4u, .6u); enddef; initsymbol ("p_gradient_AMER"); endcode Philip Schuchardt On Wednesday 03 May 2006 11:34 pm, Wookey wrote:
British cavers are complaining that therion doesn't have a BCRA-type slope symbol. I know I know learn metafont and do one myself but time is short and i'm hoiping it's easy for an expert so I can get MArtin to do it :-)
Here: http://cucc.survex.com/expo/smkridge/161/300dpi/balley.png and http://cucc.survex.com/expo/smkridge/161/300dpi/knoss.png are examples showing typical use - the filled black triangles in boulder alley and the smaller ones at over the rainbow, then more in knossos chamber, tower blocks,tower hamlets and waterfall chamber.
Long thin ones are used for very steep slopes. Short fat ones for more normal sloping floors.
Can you help, or give me a lcue for where to start doing it myself?
Also I just noticed there is a therion 0.3.10. Did I miss an announcement for this? I'll do a debian upload now I know about it, anyway.
