[mapserver-users] color. jpegs not showin up

[Tyler Mitchell]

But your mapserver isn't configured to display jpeg support.  When you do:
> mapserv -v
you need to have it saying OUTPUT=JPEG in order for mapserver to create
images in that format.  GDAL will allow you to READ JPEG images for mapserv
to display them.  But mapserver needs to be configured to display/output
them.  If you don't want to recompile mapserver, then switch to using PNG
files instead since it is already supported  in your mapserver program.
I'm not sure what is involved, but there is an image type setting in your
map file that specifies which format to use.   I suspect it is set to JPEG
right now - try changing it to PNG.

I am using gdal 1.1.5 to display 24, 8 bit TIFFs. As suggested by Frank
Warmerdam I got my TIFFs to display after I compiled gdal after
configuring it with internal tiff and geotiff libraries.
However I still get an error when I try to display colored jpegs:
drawJPEG(): Image handling error. JPEG support is not available.
These are my configs:
Banshee[20] pushkar$ mapserv -v
MapServer version 3.5 OUTPUT=PNG OUTPUT=WBMP SUPPORTS=TTF INPUT=EPPL7
INPUT=GDAL INPUT=SHAPEFILE
Banshee[99] pushkar$ gdal-config --formats
gxf gtiff hfa aigrid aaigrid ceos ceos2 iso8211 sdts raw dted mem jdem
envisat elas fit gif jpeg png
I have disabled jpeg support in mapserv, and my gdal is configured
to handle it. Still doesn't work?
If anyone has experience with this please help. Thanks,
