[mapserver-users] Image quality

[Travis Kirstine]

I am having issues with the output image quality of MapServer.  I have
a mapserver set up as a wms server up high res orthophoto images.  The
images are in tiled geotiff format with JPEG / YCBCR compression with
internal gaussen overviews and referenced using a tile index in the
mapfile with the PROCESSING RESAMPLE=BILINEAR directive.  Mapserver
5.6.7 is set up using AGG with imagemode RGBA.  I have noticed that
the images generated have aliasing in areas of high contrast when
viewing at various scales (full res seems fine).  What is the optimal
setup to reduce this effect?
