[GRASSLIST:10540] Re: Labels and ps.map

[Michael Barton]

Nick,

Point vector attribute display in d.m and gis.m is done by d.labels--with
original labels file prepared by v.label (or by hand).

There is a fair amount of control over the display possible. However, the
labels ultimately are rendered to the screen as rasters. Gis.m can output
the screen to EPS or a postscript device now (if you have ghostscript
installed). However, it is output as a postscript bitmap/raster image. If
you make your map display larger, it might give you higher resolution in the
final EPS.
