J.F. Do you have symbol and layer definitions handy? Steve
>>> "Doyon, Jean-Francois" <[EMAIL PROTECTED]> 03/02/06 12:45 PM >>> Here is a visual sample of the symbology problem: http://atlas.gc.ca/mapserver-symbol-problem.png Note on the left a sample of the legend. The most obvious problem is for the symbol for Aurora ... Though others also have issues. This is using: MapServer 4.8.1 GD 2.0.33 FreeType 2.1.10 Forcing ANTIALIASING OFF on the symbol definitions doesn't really seem to help. In the cases where symbols have overlays, playing with the sizes helps some, but often circles insist on coming out ever so slightly distorted (i.e. a slightly oval shape). There's also reports that a certain symbol will have the proper shape only with a specific size. Res-sizing the symbol distorts it? Anybody run into anything like this, or have any idea what's going on here??? The cartographers are going crazy here ...

This however seems inconsistent. Some layers have fine looking POSITION ll labels, while some others show offsets that are wayyy off. For a while even th wrapping was acting strangely, adding lots of vertical spacing between 2 lines of a label. I've tried in vain to get one layer's label's to appear like another's in vain. The one that looks "wrong" always does, no matter what we do. We can have 2 layers with the exact same font, font size, placement, and so on, and one will label as expected, and one won't. I have NO idea how/why this happens. We've noticed things like this before between versions of mapserver ... We use lots of basolutely positionned labels, so this is problematic. Also, the symbols now seem to be anti-aliased or something, in a different way? The symbols in the legend look blurry and deformed. The symbols within the map also seem to be bleeding colors ... It's all very weird. I'm going to get some screen shots and put them up somewhere so everyone can look at them, I'd be very interested in hearing about other's experiences with this!
