Hello Astrid,

I use Mapbender 3.3.0. As you recomended I created GetMap request with Transparency parameter set on True. This is the result: https://pasteboard.co/TVfZV2ctv10s.png
and the request:

I tried changing the BGCOLOR, but the background remains black. So it's not a Mapbender bug (good job 🙂 ), but do you have any idea what I can change to make it work, I would appreciate any suggestions.

See you,

Hello Marcin,

what version of Mapbender do you use?

There was a bug, that Mapbender does not send the parameter
TRANSPARENT=TRUE in upper case in the getMap-Request. Some services
ignore the parameter, when it is in lower case.

Image png is fine for a layer with transparency

Please check your getMap-Request and modify it. If TRANSPARENT=TRUE
solves the problem you can go to the Mapbender code and fix it.

You find a desciption here:



The fix will also be available in the next version.

See you Astrid
