Sat-picture - no colors!?

[Leopold Schefcik (MULTIMEDIAPLAN.AT)]

hi,

My sat-picture has about 16,7 Mio colors but in the client only about 256
grew-colors.

I tried to change PNG to PNG24, but it's still b/w.

When I change  IMAGEMODE PC256 to MAGEMODE "png24" or IMAGEMODE png24 my
GetCapabilitiesRequest isn't accepted any more.

Some other idea to get the colors displayed.

best regards - Leopold

Hi Leopold,

Q1: you will need to use a style that uses a vector symbol, e.g.

SYMBOL
   NAME "circle"
   TYPE ellipse
   FILLED true
   POINTS
     1 1
   END
END

then you can use the SIZE parameter in the mapfile on that symbol.

Q2: Are you sre mapserver finds your shapefile in ./data? Did you try to
use an absolute path to your data directory?

Q3: Not sure, but did you try using a 24-bit output format, e.g. png24 ?

Cheers, Michael
