[Vis5d-users] Re: saving pics in little endian machines, USE_SYSTEM_FONTS

Jaakko,

THANKS I=B4m glad to here someone out there is using the CVS version.    =
I=B4ve applied your patch to
gl_to_ppm.c  and cleaned up the work.c  (the patch failed because i had a=
lready made another
change)   By the way defining  USE_SYSTEM_FONTS  causes your contour labe=
ls to be plotted using a
font loaded from the system rather than the one generated within vis5d.  =
This makes for a much
more readable contour label.  In the lui5 interface there is
only one font defined for the 3D window and it uses that one.  However th=
e gtk interface will
allow for the definition of different fonts for the various objects you m=
ight want to label...
