the fix for <span class="sg"><a onclick="return top.js.OpenExtLink(window,event,this)" href="http://trac.osgeo.org/mapserver/ticket/2264#comment:6" target="_blank">http://trac.osgeo.org/mapserver/ticket/2264</a> introduced some regressions that result in artifacts on thick lines and font outlines (anywhere else ?). will be looking into this soon.
<br><br>as for cartoline endcaps and joins, the documentation already exists, but will have to be updated for agg: <a href="http://mapserver.gis.umn.edu/docs/reference/symbology/syntax">http://mapserver.gis.umn.edu/docs/reference/symbology/syntax
</a><br>I'll keep you updated when those keywords will be taken into account for line drawing<br><br>what should the default endcaps and joins be?<br></span><br><div><span class="gmail_quote">On 8/27/07, <b class="gmail_sendername">

</a><br><br>I noticed that the endcaps of fat lines used to be rounded like GD, but<br>now it abruptly ends. look at the ends of the test spiral and the roads<br>on the bottom of the side by side comparison.<br><br>Also, You meantioned a while back that some or all of the cartoline
<br>endcap styles worked with AGG, could you review for me and the doc team<br>what the keywords are and how to include them in the AGG layer definition.<br><br>Thanks,<br> -Steve W<br></blockquote></div><br>
