Thanks for asking that question Michael I have the same problem, but I had not bothered to think about changing the linework colour.
I just tried a simpler approach (that leaves the header and grid coordinates black). I will use this from now on. symbol-colour group all [60] #makes everything grey colour map-fg [97 86 38] #add some colour And check out this code to make the grid grey http://therion.speleo.sk/wiki/doku.php/metapost?s[]=change&s[]=grid&s[]=symb ols#special_symbol_examples Code to change grid symbols from cross hairs to continuous lines Thanks Bruce (I don't know how to change the pen colours) -----Original Message----- From: therion-bounces at speleo.sk [mailto:[email protected]] On Behalf Of Michael Wasmund Sent: Tuesday, 19 May 2015 12:00 p.m. To: therion at speleo.sk Subject: [Therion] Redefining PENA...PEND to draw lighter Hello, Does someone have metapost code to redefine PENA...PEND to draw grey instead of black? Why I need this: My survey consists of 80% scanned bitmaps and 20% drawn scraps. The bitmaps are "grey", not black (can't make them better using image processing). The drawn scraps then stand out and look ugly compared to the bitmaps. I know how to redefine individual symbols (walls etc.) to be grey instead of black, but rather than redefining a large symbol set I'd rather redefine the PENs - if possible.
