for an overview map I need to specific the labels I want to have in the output. Just sorting them by size is not possible. After searching I found a label re-definition at http://marcocorvi.altervista.org/caving/tbe/m_07/m_072.htm (7.2.10).
Works like a charm in a small cave but taken to my project it behaves odd: If I compile, Therion (5.5.6) gives this error (and creates no map): converting scraps ... done making map ... C:\Program Files (x86)\Therion\therion.exe: error -- Can't open file data.8bbox!
Therion expects to find a *bbox file for each scrap containing labels. It is generated by metapost when the labels are processed. In your case, you instructed metapost to skip all the labels in a scrap (so no *bbox file was produced), but therion knows there were some labels defined for that scrap (if you displayed at least one label in the scrap, the *bbox file would be generated). The easiest solution is to create an empty *bbox file if there is none by writing an empty string to it. Here is a modified Marco's macro: vardef p_label@#(expr txt,pos,rot,mode) = if known ATTR_visibility: if ATTR_visibility="on": % ADDED CONDITIONS if (mode=1) or (mode=7): interim labeloffset:=(u/8). fi; lab:=thelabel@#(txt, pos); if mode>1: pickup PenD fi; if mode=1: % altitude pickup pencircle scaled (u/6); drawdot(pos); process_label(pos,0); elseif mode=2: process_uplabel; % passage height positive elseif mode=3: process_downlabel; % passage height negative elseif mode=4: process_updownlabel; % passage height both elseif mode=5: process_circledlabel; % passage height unsigned. elseif mode=6: process_boxedlabel; elseif mode=7: process_label(pos,rot); % station name elseif mode=8: process_filledlabel(pos, rot); else: % mode=0 date process_label(pos,rot); fi; else: write "" to jobname & "." & decimal(charcode) & "bbox"; fi; else: write "" to jobname & "." & decimal(charcode) & "bbox"; fi; % END OF CONDITIONS enddef;
However, if I put in the –d command it compiles and produces the warning: warning -- cavern exit code – 1 But it creates a nice map showing the labels I want.
There was surely some old data.8bbox file in the thTMPDIR, as therion doesn't clean this directory between runs in the debug mode. Check the timestamps of the files. Best wishes Martin
