Hi,
By default, without having any OUTPUTFORMAT sections in the mapfile,
Mapserver is advertising following imageformats in WMS GetCapabilities
document:
<GetMap>
<Format>image/gif</Format>
<Format>image/png</Format>
<Format>image/png; mode=24bit</Format>
<Format>image/jpeg</Format>
<Format>image/vnd.wap.wbmp</Format>
<Format>image/tiff</Format>
<Format>image/svg+xml</Format>
Some users have been confused because WMS client builds menu items
according to that list, but at least "image/png; mode 24bit" and
"image/tiff" do not give any output. What is the reason to include these
formats in getCapabilities by default, if they do not work without
creating OUTPUTFORMATs in the mapfile first?
Jukka,
I don't know why image/tiff and image/png; mode=24bit would not work.
Perhaps you could file a ticket with minimal details to reproduce this
problem. Please include the mapserv -v string in the ticket so I can
try to reproduce a similar scenario. Assign the ticket directly to me.
Second question is about JPEG outputformat. It works through GD with
these settings
OUTPUTFORMAT
NAME "jpeg"
MIMETYPE "image/jpeg"
DRIVER "GD/JPEG"
EXTENSION "jpg"
IMAGEMODE RGB
END
If I change driver to "GDAL/JPEG" I get this error on ms errorlog
[Mon Mar 16 11:16:05 2009].825000 msSaveImageGDAL(): General error
message. Failed to create output JPEG file.
JPEG driver doesn't support 4 bands. Must be 1 (grey) or 3 (RGB) bands.
What makes GDAL/JPEG driver to believe that I want 4 bands? Or is it
just best to use DG/JPEG always?
I'm surprised. This should not occur with IMAGEMODE RGB. I would
appreciate your also filing a ticket on this issue and assigning it to
me.
Best regards,
