Indeed, that seems to be the problem. Comparing the output from the following code gives the svg as smooth but the png not smooth. p = plot(2*r- r^2, r, 0,1) + plot(1, r, 1, 2) p.save("plot.svg") p.save("plot.png") -- You received this message because you are subscribed to the Google Groups "sage-support" group.
