Re: [ferret_users] thicken lines in postscript output

[Andrew Wittenberg <Andrew.Wittenberg@xxxxxxxx>]

Ferreters,

On the same topic, see below for a tiny C-shell (csh) script that will 
thicken all Ferret PostScript lines by any integer factor.  You'd put it 
somewhere in your path, and make it executable with "chmod +x ps_thicken". 
Run "ps_thicken" without arguments for a usage message.

Andrew


#!/bin/csh -f
# Usage: ps_thicken ps_file factor

# get list of all arguments
set args = ($*)

# if not enough arguments, complain.
if ($#args < 2) then
   echo "Usage: ps_thicken ps_file factor"
   echo "Thickens all lines in a PostScript file by changing the linewidth macro."
   echo "Result goes to standard output."
   echo "Example: ps_thicken myfile.ps 3 > myfile_thick.ps"
   exit 1
endif

sed -e "s/^\/lw {\(.*\) div setlinewidth/\/lw {$2 mul \1 div setlinewidth/" $1
