that's how the agg antialiasing works, I'm sorry but I don't think there's a way to avoid that. As david points out, the effect is amplified if the feature is drawn mutiple times, eg with adjacent outlined polygons.
you can observe the same kind of output on all webmaps. http://maps.google.com/maps?hl=en&ie=UTF8&ll=19.890723,-3.691406&spn=53.567248,81.210938&z=4&om=1 on the line between mauritania and mali http://maps.live.com/default.aspx?v=2&cp=42.157041~-0.353622&style=r&lvl=11&tilt=-90&dir=0&alt=-1000&encType=1 on the yellow/red road east of huesca and north of tierz ... concerning the format, you can probably get smaller images using the formatoptions to either quantize or use a forced palette (which is faster if the palette contains exactly 256 colors) regards, thomas On Jan 8, 2008 12:40 PM, Flavio Hendry <[EMAIL PROTECTED]> wrote: > Hi list, hi Thomas > > When using AGG output, lines at near horizontal/vertical angles become > "fuzzy".
