hi devs,<br>I've commited a few changes to the agg rendering logic, which greatly increase performance when drawing many shapes. what's changed is that the imageObj now holds a pointer to the rendering object and all it's dependencies, instead of recreating them nearly from scratch each time a shape is drawn.
<br>on the "ntdb_roads_50" from a recent osgeo-discuss post<br>before: 1.1seconds<br>after: 0.5 seconds<br><br>this is still much more than what gd does, but getting closer (that particular test file is probably a worst case scenario when comparing rendering times: many tiny line segments that just show up as a pixel with gd, but all have to be antialiased in agg)
<br><br>all this to say that I don't think there should be much breakage arising from this, but I'd appreciate if all of you who are set up to test agg could give the new version a run and report if anything weird is happening.
<br><br>thanks,<br>thomas<br>
