Description (last modified by )
The "title" of a raster map is part of ps.map's "header" instruction. Defining a title to a raster map (r.support) with more than 100 characters, causes a segfault when trying to draw this map with ps.map.
Tested using data from the "spearfish60" Location in both G6 and G7, e.g.:
# under G7 -- set a low resolution for a quick test! g.region res=1000 -pa # define raster "title" r.support landcover.30m title="123456789 123456789 123456789 123456789 123456789 123456789 123456789 123456789 123456789 123456789" # ps.map-it ps.map --v in=spearfish_landcover_30m.psmap out=spearfish_landcover_30m.ps Scale set to 1 : 21668 Reading raster map <landcover.30m@user1>...

Replying to neteler:
There seems to be a (wild) mixture of buffer lengths for the raster map title:
Compare:
- http://grass.osgeo.org/programming7/put__title_8c_source.html#l00016 int Rast_put_cell_title()
- raster/r.support/main.c: #define MAX_TITLE_LEN 1022
- r.clump/main.c: char title[512];
- r.los/main.c: char title[128];
- r.neighbors/main.c: char title[1024];
- r.param.scale/close_down.c: char map_title[80], map_type[32];
- etc
- ps.map/ps_info.h: char celltitle[100];
Interesting mixture :-). If it is not possible to equalise all these, maybe, at the very least, warn the user to "conform" to a fixed length and below, and not letting him to a scary seg-fault?
