Hello again, i want to define an optional layout in which some formations are colored differently, however i have no idea what to do. Following the examples in the wiki, i tried: ------- layout colorMap.layout symbol-colour group water [30 30 95] #this works! :) symbol-colour line chimney [0.95 0.15 0.15] # no change :( symbol-colour line ceiling-meander [0.95 0.15 0.15] endlayout ------- The water color changes like expected, but the chimney and meander parts remain black :( What am i doing wrong here? Also the same occurs with sand and clay patterns, however here i did my custom version: -------- code metapost % --- LEHM --- beginpattern(pattern_clay_AUT_HVHO); % Zeichnet einfach eine Reihe punkte an fixen X/Y Koordinaten pickup PenC; draw (0.20u, 0.30u); draw (0.35u, 0.70u); draw (0.40u, 0.40u); draw (0.60u, 0.50u); draw (0.80u, 0.10u); endpattern; def a_clay_AUT (expr Path) = T:=identity; % thclean Path; %thfill Path withpattern pattern_sand_AUT ; % original thfill Path withpattern pattern_clay_AUT_HVHO ; enddef; % --- SAND --- beginpattern(pattern_sand_AUT_HVHO); % Zeichnet einfach eine Reihe punkte an fixen X/Y Koordinaten pickup PenB; draw (0.20u, 0.20u); draw (0.40u, 0.60u); draw (0.80u, 0.40u); patternbbox(0u,0u, 1.0u,1.0u); % definiert Rechteckgroesse des Symbols endpattern; def a_sand_AUT (expr Path) = T:=identity; % thclean Path; %thfill Path withpattern pattern_sand_AUT ; % original thfill Path withpattern pattern_sand_AUT_HVHO ; enddef; endcode --------- I think i need to tell Therion somehow to draw the line in the color specified using "symbol-colour". I know i could duplicate metapost code and add my colors there, however i want to use the distributions symbol definitions here if possible (maintianing upwards compatibility). Thank you very much!
