I tried changing the text colour to 1 0 0 ,instead of 0 0 0 and the =
problem disappears.
The text is now readable but interestingly still has a little shadow of =
whiteness on the right hand side.
If I try the ANTIALIAS FALSE I don't get the shadow but the text does =
not look as good.
Using the bitmap the text is perfect, except the font doesn't look very =
good.
=20
In summary I think I'll use the ANTILALIAS FALSE option with the =
truetype font with a colour of 1 1 1.
=20
Many thanks again for the replies,=20
Craig.

Craig,
mapserver as client processes WMS layer as other raster data. If the =
picture has transparent background, underlying data are seen too.
When I am thinking about this, your problems may also be caused by =
background color and transparency colision in the picture. Please try:
=20
1. temporarily change the text color - what is the result?
2. show the WMS maps in some DHTML client (maps are stacked at the =
client html page) e.g. www.wmsviewer.com
=20
Are your WMS maps seen from world? What is the address? I'd like to =
test them.

Thanks for the reply. The text returns when antialias false is turned =
off.
=20
However, I don't really understand how this would make any difference.
The png file being created by the server has the text in, it's just =
when it's merged with the client map that the text dissappears (in the =
case of antialias false) or becomes fuzzy (in the case of antialias =
true).
=20
Forgive my ignorance but how do the client and server images get =
merged?=20
Could the caause be in the merge somewhere?
=20
Thanks again
Craig.

Stepan,
The labels disappear completely when I use the ANTIALIAS FALSE =
option

Your layer uses anti-aliased fonts (to be smoother) as default =
option. Try set ANTIALIAS FALSE in the LABEL object:

Folks,=20
Excuse me if I'm being daft here as I'm pretty new to this WMS =
stuff.=20
I have some layer labels coming through a WMS server that when =
displayed on the client map lose their focus and become off colour and =
fuzzy. They are supposed to be black, but appear in the final image as a =
mix of grey/white/black. Hopefully my image attachments will appear on =
the list. If not then please mail me for them if you know anything about =
this.
The WMS server is passing an image that looks just as it should, =
e.g.=20
<<1082638016134960.png>>=20
However, when this is placed on the client map the labels appear =
like this:=20
<<DEMO108263801613496.gif>>=20
Both maps are using the British National Grid projection =
epsg:27700.=20
My client map layer looks like this:=20
LAYER=20

TYPE RASTER=20

END=20
END=20
[ For the sharp eyed among you, you may notice this is directed to =
an asp page. This redirects the request to the mapserv cgi-bin script =
with all the same parameters but without the epsg parameter as this is =
the only way I can get a client using projection 27700 and a server =
using the same projection to respond with a map. Mapserver crashes with =
a page fault otherwise! This is not restricted to just epsg 27700 - if =
the server/client has the same family of projection as 27700 this page =
fault will occurr. Not knowing enough about the projection code and =
being too dum to get it to compile on my own windoze machine I've failed =
to trace what's causing this problem ]
