I don't quite understand why your transparent areas are exporting as Black:

I want to compose an image using a bunch of LC objects, then export a

that part's not critical).
The documentation for export snapshot is not very clear. I've tried
things like exporting a transparent group containing some objects; the
PNG was just filled with black where there were no objects.
There is an option "with mask xx", but it appears that this is only
for PBM format - and in any case I can't make it work.
Is there any way to do this?
TIA
