Bob,
Sounds like the "type" of PNG is causing the problem. Have a look at
the properties (using gdalinfo) of the PNG image the wms produces (use
"curl" to get and save the image. Is it RGB? RGBA?
Best Regards,
Brent Fraser

Hi Adam,
I doubt it, but I won't rule out anything. But the MapServer
(non-WMS) layers display fine, so that's one thing that doesn't make
sense.

Is it possible the issue is with the CSS of your print stylesheet?

Hi all,
I've posted this to the GeoMoose list since the problem was occurring
in a GeoMoose application, but also would like to see what insights
there may be here on the MapServer list. Sorry for any duplication.
I have a few WMS layers that I consume in GeoMoose. Some of these are
vector line layers such as roads. They look correct in the
application's map view. But when I compose a printable map, these
layers have a black background which obscures other layers. If I set
the "transparent" property to false, the black background goes away,
but then I can't see any underlying data.
By the way, I do have control over the WMS services in this case. I
tried to set Offsite to 0 0 0, but that didn't seem to help either.
The image format should be png, and as best as I can tell, this is
what it's producing. The WMS is at MapServer 6.0.1, while the
application is at MS 5.6. It appears to be some problem with the
alpha channels. Any suggestions?
