<DIV><FONT face=Arial size=2>Serving a satellite image ECW (approx 4GB file) as
a MapServer CGI consumable. While a 24bit PNG looks great, the filesize can be
quite huge, therefore I've modified to serve it as a JPEG with QUALITY set to
100. This still looks good and gives a very small filesize compared to the PNG.
</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Now here is the main question, when serving the
same layer as a WMS service, the JPG looks really washed-out, where as the PNG
while looking great has too big a filesize for the end-users. So I was wondering
if there was a bug with Mapserver or GDAL (as I take it MapServer uses GDAL to
serve ECW's), or if anyone out there has a solution? </FONT></DIV>
