Hi all,

I'm using plplot with the pdl interface.

I'm using the plsdev("png") and when I draw plain circle using plpoin, they are far from being pretty circles,
more close to potatoes :-). Naturaly, this is a global issue: letters and other symbols are also

I've tried using plsetopt to set "compression", "dpi" inline argument and even
"drvopt" but with no success.

 I'm a bit disappointed since the quality of the example on the plplot website
is exactly the quality I'm expecting (and circles and circles, not potatoes :-( )

Probably, the solution is in a setting of GD or maybe libpng?
Does anyone has any idea of how I can set the relevant environment variable?
Is it a problem of resolution or of compression?
