[mapguide-users] WMS questions

[Brian Flood]

thanks

via the Author...

also, after closer inspection turning off the outline does not fix the
issue, it just makes it harder to see. (on the right side this time)

Note the dithering of the GIF image as well (I need transparency in all
browsers so no png). Not much you can do there I guess. Are you guys
optimizing the GIF palette? I know the default GIF codec in .Net does not
(unless this is changed in 2.0). The antialiasing and non default palette
colors would look a lot better if this occurred.

mapguide.osgeo's Project Tracker (left panel) is the place to enter
suggestions, defects, and enhancements.

BTW, were you thinking of controlling (anti)aliasing by the author (in
studio) or by the client (via WMS parameter)?

thanks Traian

1) If you happen to know, how would I go about doing this?

2) yes, this was it. Turning off the outline prevents this from
happening
although, as you stated, this is not a very good work around.

1) No. Currently there is no way to turn off antialiased drawing. You
can
enter this as an enhancement request.
 
2) My guess is that this may be caused by a polygon layer that spans
many of
your tiles and is getting clipped to the extent you request, resulting
in
the black lines. The WMS serving component uses a map rendering call
that
does this kind of clipping. May be we should switch it to not clip, like
what the tiled AJAX viewer uses. Or fix the polygon clipper to not
generate
polygon segments that parallel the image bounds. Anyways, this will be
fixed. As a workaround (not a perfect one), you can try turning off the
outline of that polygon layer.

hello all

 

1) Is there anyway to turn off anti-alias drawing (per layer
preferably)?

 

2) I keep getting a solid black line on the left and top edges of images
returned. When tiling requests together (think Google Maps custom
layer),
this creates an unwanted grid pattern. Any thoughts?

 

cheers
