[OpenLayers-Users] AW: [mapserver-users] "Low-resolution" raster image problem when usingOpenlayers

[Arnd Wippermann]

hi,
 
if you do a right click on a tile to get the context menu, you should be
able to copy the url (if the tiles of your server is the most top of the
visible layers). Compare the different urls. If you load them in your
browser you should get a response for a single tile from your server.
 
Perhaps that gives you an idea, what goes wrong.

Betreff: [mapserver-users] "Low-resolution" raster image problem when
usingOpenlayers


Hi!

I am trying to use MapServer as a WMS layer in Openlayers. I setup the
MapServer in our server machine, using my own PC as the test client. I
created a simple .map file in our server that contains one raster image.
Using the mapserver tool 'mapserv' in a URL string, I was able to load the
output map with full resolution correctly in a browser (Google Chrome).
However, when I tried to load the map using a simple Openlayers script
(HMTL) which I created on our server (accessible via browser), the map image
appeared to have a much lower-resolution (i.e. 256-colors only) and was
pixelized. Also, I could see white lines representing the tile edges of the
map. 

I did another test. This time, I installed MapServer in my own PC. I created
a .map file similar to the one I used in our server, with the same raster
image. I created a similar Openlayers script (HTML) in my own PC, but this
time it would call the MapServer from my own PC. I loaded the script using a
browser and the image displayed correctly with full resolution. 

Does anyone have an idea what the problem could be?

I would appreciate any help in this matter.

Thanks in advance! :)
