However, the quantity of information to encode in an antialiased image rendering is higher than in a non antialiased one, thus the higher file size when using agg/png8 vs. gd/gif. Even if we were to add a an agg/gif format, you would still be seeing this size overhead.</div>

<div dir="ltr"><div class="gmail_extra"><div class="gmail_quote"><div>To put this bluntly, if the 15% overhead is important for you, you would have to stick with gd aliased rendering and the 6.4 release. I would also like to put this in context: a 15% overhead compared to the 2001 (2005?) outputs does not seem like a big deal given the evolution of available bandwidth since that time.</div>

And when considering bandwidth we need to keep mobile applications in mind alos. MapServer has always been synonymous with speed and from the user experience perspective speed is determined by the whole pipeline.<br>

I was mainly wondering if there was a way to reduce the anti-aliasing (and consequently the rendered image file size) when using AGG, which I'm sure sounds like a pretty silly question given the "A" in AGG.<br>
