Of course you can define as many attr xyz as you need, and create different layout definitions to select them at will. - Ben

Although ultimately it would be good to move away from having to modify each station with text in the th2 files each time we wanted to toggle the output of text for individual point types (mark or flag), and move towards putting this type of control back into the layout files. A symbol-show, symbol-hide that pertained to the text comment for stations with specific mark and flag combinations would perhaps be ideal. So we could have control of printing each of the three components of station individually (mark, flag symbol, text) dependant on the mark and flag status of each point. Of course having a fourth controlling factor or override, ATTR_print, as you have come up with is useful as well.

For each station that you want to print the text for, set attr print "true" in the th2 file as I illustrated in my earlier email. If you want to turn off printing you can set the text to "false". This works for any station, no matter what its subtype or flags that are set. The code is as follows: layout l_p_station_text code metapost def p_station(expr pos,mark,txt)(text flags) = % draw default station p_station_SKBB(pos, mark, txt, flags); % now print the text if picture(txt): picture ATTR__text; ATTR__text := txt; if known(ATTR_print): if (ATTR_print="true"): if not numeric txt: p_smartlabel(txt,pos); else: % draw filled label with text next p_label.urt(ATTR__text,(.5u,-.25u) transformed T,0.0,8); fi; fi; fi; save ATTR__text; fi; enddef; endcode endlayout -------------- next part -------------- An HTML attachment was scrubbed...
