Re: TPad based legend shown on screen and eps, not png/gif.

Hi Brett,
I LIKE such extreem examples :-) a good chance to improve and optimize a code. Yours TGraph has 477575 points (!!!). Thanks, that they are not drawn as polymarkers. Nevertheless I hope to improve very much TImageDump's performance for such cases.

Thanks for example. Regards. Valeriy
