The above are compiled into the therion executable in some way so that therion knows about those area symbols. If I want to override one of the above area symbols with my own metapost code I can do that by including the metapost code in thconfig.
Yes, you can override only existing symbols.
But if the area symbol is not in the list above I can't just create metapost code for say "a_something_ASF" as therion will not know about it even if it's in thconfig.
Is that right?
Well, symbol types/subtypes are in fact defined in thpoint/thline/tharea.h/.cxx files. In metapost files, there is only their visualization defined, therefore it does not help to define only new metapost symbols.
Now I understand. Thank you.
Soon we would like to add some generic point/line/area symbols, that could be used in cases, when desired symbol does not exists in therion.
I'm learning about metapost and how to pull in survex data via a 3d file and my wife is drawing up the cave we are surveying with the xtherion map editor. There are quite a few ASF symbols that she needs. Mike -- Michael Lake Computational Research Support Unit Science Faculty, UTS Ph: 9514 2238
