Re: [mapserver-users] Turn off anti-alias Mapserver 6.0
Hi Thomas You could try to reduce the image size using 8bit PNGs, see the 3rd output format in http://mapserver.org/mapfile/outputformat.html.

RE: [mapserver-users] Turn off anti-alias Mapserver 6.0
Hi Thanks for the quick response I also tried PC256 as discussed in the outputformat instruction sheet. Although the image did look similar to the results from 5.7 and the size was much smaller it did not render transparent polygons correctly. I may have missed something else here. Is there a way to turn off anti-aliasing with the AGG driver ?

[mapserver-users] pointObj-project behaviour differences from 4.10 to 5.6 versions
Dear list, I have a webgis application working with different CRS all over the world. I have realized that the behaviour from version 4.10 of the function pointObj-project differs from the one of version 5.6 from Mapserver. For example, I try to convert (-116,-15) in 4326 and in mapscript from version 4.10 it returns (-26158630.407638,-25040425.679281) when passing to 32630. On the other hand, in version 5.6 of mapscript it returns the original coordinates without transforming them. Is this intended or am I doing something wrong? Which is the intended behaviour of project function in MapServer 5.6? Best regards, -- Juan Manuel Moreno Rivera.
