Description Ulrich Windl 2011-11-07 23:47:15 UTC

When exporting a drawing that uses transparent areas, some export filters (e.g. WMF) use a solid fill instead. There is no warning during export about that fact.
I don't know if WMF could do transparency (if so, that would be another bug), but a warning would be nice.
(PNG exports do transparency properly, but lack good resolution; SVG exports do transparency, but the writer cannot import (or at least display) SVG images)

So either support transparency better, or at least warn now that transparent areas aren't properly rendered.

I can not reproduce this in Draw 3.5.0. Please, if it is still reproducible, attach document that demonstrates this problem.

[Reproducible] with server-installation of Master " 3.7.0alpha0+  – WIN7 Home Premium (64bit) ENGLISH UI [Build ID: b255de8]" (tinderbox: Win-x86@6-fast, pull time 2012-06-05 23:16:58) and attached test kit. Exported sample.wmf does not show transparency.

@sasha
What did you test that you got a different result?

Thanks for reproducing.
Draw 3.5.4 on Fedora 64 bit still exports to wmf with transparency. May be I do something wrong. Please, attach source odg file for tests
