[mapserver-users] AGG: Internal vs. External

[Alberto Najera]

Hello

I am using Mapserver as a WMS server and would like to improve the rendered
image quality. Currently we get jagged lines and poor text rendering as  you
can see in this link

http://www.bicimapas.com.mx/SpatiaRetail.html


Source are SHP files. We plan to use AGG to improve this and are using
Mapserver 6.01. I have not installed AGG  but when running /.configure it
shows AGG Support: Internal and with ./mapserv -v shows  SUPPORTS: AGG.

The question is whether there is a difference between internal or external
AGG support?   Is this internal AGG support provided by GD?  Finally, is
there a suggestion on how to improve the image rendering quality?


The map file has this image rendering setting:

MAP
NAME "DemoFerre"
UNITS dd
SIZE 640 480
IMAGECOLOR 244 244 244
IMAGETYPE png
SHAPEPATH "/home/bicimapas/mapdata/"
EXTENT -99.070427 17.869010 -96.723984 20.839951
FONTSET "/home/bicimapas/mapdata/fontset.txt"


Thanks in advance
