[mapserver-users] resolution

[Alan Boudreault]

Hi 

Set the DEFRESOLUTION to 72 (I assume all your mapfile settings are for a 
72dpi image) , change the RESOLUTION to 300. Change your map size if you want 
a big 300dpi image.

It is possible that the image header doesn't contain the DPI information. This 
can easily be modified with a graphic program like "The GIMP".
