Graphics mavens, help me to antialias [mi]

post by: orthogonality at: 04:21 | 3 comments

I have some roughly circular lines, output with gnuplot to a png file.

gnuplot doesn't anti-alias. How can I antialias these plots to make them look smoother?

Bonus: how can I do this from the command line, in a typical linux setup.

Here's what the output looks like, at 400% zoom:

Export to EPS from gnuplot, then convert to PNG (eps2png).

To second Alex's suggestion I use the following ImageMagick command to convert a graph in post script format:
convert -density 288 -geometry 30%% c:\bat\graph.ps c:\bat\graph.png
Comes up lovely.
