Re: gnuplot: set terminal png

[Henry F. Mollet]

On Mac another way is to save as pdf in AquaTerm. Then open the file in
Preview and save as PNG. Quality of png on screen looks just as good as pdf
(viewing a contour plot). I have not checked if there's a difference when
printing. Size of pdf was 52 kB and surprisingly? increased to 132 kB for
png file.
