Re: [ferret_users] Odd lines on postscript with fill command

Hi Stephen,
I checked back and here is the proposed solution. Note that this helps with rendering of
ps (and eps, I think) files but I am not sure if it will help with the pdf.
If you open .ps file in ggv, go to Edit->Poscscript Viewer Preferences and unckeck the
antialiasing box. The lines *should* disappear.
Hope this helps in any way!

I am seeing some unwanted, odd thin white lines on my postscript plot
(attached pdf).  I remember someone having similar issues before, but
couldn't find it in the archives.

Some key lines of my ferret script (note that using shade removes the
problem, but I want to use fill)...

set mode metafile:fig19.plt
ppl ylab "Radius (km)"
ppl xfor (i2)
ppl axlint,4
ppl fill
label/nouser 4,-0.55,0,0,0.15 "Day (July 2005)"

let er2 = (14*60 + 40)/(24*60) + 9
plot/vs/overlay/nolab/line/thick=3/color=black {`er2`,`er2`},{50,600}

My shell script to convert...

#! /bin/tcsh
ferret -unmapped -script plot_inertial.jnl
set file = `echo *.plt | cut -d"." -f1 `
gksm2ps -p portrait -o $file.ps $file.plt

# script to increase line weights of Ferret output
sed 's_3.000000 lw_6.000000 lw_g' < $file.ps >! foo; \mv foo $file.ps
sed 's_2.000000 lw_4.000000 lw_g' < $file.ps >! foo; \mv foo $file.ps
sed 's_1.000000 lw_2.000000 lw_g' < $file.ps >! foo; \mv foo $file.ps

convert $file.ps $file.pdf
rm -f *.ps *.plt

Note also, that sometimes fill works (for other plots).  I am using FERRET v6.1
for Linux.

Thanks for ideas,
