Re: [Geotools-gt2-users] [Geotools-devel] JMapPane not transparent after pan/zoom

[Michael B. <mic...@gm...>]

Thanks for the bug report Tom. I'm moving this thread to the user list
where it is more appropriate.

Looking at the unit tests, I see that there is nothing in place to
test background colour and I don't remember much discussion of it on
the list previously, so it's not surprising that there glitches.

Here is a Jira issue based on your post:
http://jira.codehaus.org/browse/GEOT-4168

I'll try to look into it soon.

Michael
