Re: transparent layer?

["Luis A Escobar" <luis lsu edu>]

Alan, thank you for the help.

  I meant pictures to teach the concepts of union, intercepts, etc to
  illustrate those operations. I saw the case you document and that
  is exactly what i was looking for.

  Thanks again.

Regards, Luis A

There is the FAQ web pages, the gnome documentation, and a PDF file that
gets included with the windows distribution which is the Gnome
Documentation agian (i only skim read it).

Someone recently started a Wiki (online colloborative encyclopedia type
thingey in case you are unfamiliar with wiki).

I dont know the link, so please try searching the archive or perhaps
someone else will get back to you, or if you are lucky a link to it has
been added some where on the site.

"Grokking Dia" does not have quite the same ring to it.

What exactly do you mean?

Do you mean pictures simply explaning set operations for people learning
mathematics or Dia actually performing the operations and giving you lots
of little pieces?

I just happened to have documented this kind of "set operation"
functionality from Visio as someone mentioned it recently.

and seeing as Lars answered before i did i went off and filed it instead
of rambling on in an email.

Turn off "Fill"
Partial Transparencey or Alpha Channels would be cool,
Gobe Productive does it.
