jpeg quality

[Kristjan Annus]

Are you using raster or vector input data?
If you are using raster maps to generate your jpg output, then the
problem might be in
the poor resizing quality. I have created one application in wich the
raster files were drawn
in there own native scale and then rescaled with PHP and then re-readed
back to the Mapserver
to add some more data from vector layers. The output quality was much
better then.
