savepng is indeed much faster, but the resolution is still not as good as exportgraphics

Hi,

It seems the quality of the picture exported using exportgraphics is much better. I tried different compression/resolution w/ savepng but none of them can reach the quality produced by exportgraphics. Any clue?

Cheers~

Can you provide an example? PNG is a lossless compression, I don't know how if can actually resolve in a worse quality. Resolution of the saved image is wholly depended on the the RGB matrix you pass in to savepng().
