Additional content for AGG Rendering Specifics Howto

[woodbri]

Thomas posted the follow to the users list which might be of interest to people generating tiles with AGG. This should probably be added to HowTo? page "AGG Rendering Specifics":

Just a side note on the subject: seeding your tiles probably involves using tilecache's metatiles. quantizing a 5x5 tile in mapserver will very probably give poorer visual results than quantizing each individual tile. For this reason I tend to seed in 24bit mode, and postprocess the split up tiles with pngnq:

for file in `find tilecache/mylayer -name "*.png"`;
do
 echo $file;
 pngnq -e .png.tmp -n 256 $file;
 mv $file.tmp $file;
done

I am not sure if this should be included in the docs, and in case it should be included - where to include it and how.

I add Thomas on the CC list, and hope that he can decide what to do with this ticket.

I'll deffer to Thomas on this, but my sense is that this is somewhat out dated and I'm not sure it applies to mapcache. I'm ok if it is closed as "wont fix".

mapcache and mapserver can do this step natively, and this is really related to tilecache, not mapserver.
