Hi guys,

Looking at the XComposite protocol, looks like you're
using CreateRegionFromBorderClip, and having a look to
Xfixes -wich I haven't had read anything about
before-, looks like you're using
CreateRegionFromWindow.

But once again, I cannot test any of that till I've
ahieved to extract a 1bit image from the original one
(I'm quite close already).

I've tried today to use Xfixes, which would make my
life much easier, and could even help me with this,
seeing it done from another perspective, but it looks
like fuctions like CreateRegionFromPicture, and
CreateRegionFromGC are not yet implemented, although I
can see some related source code within my
distribution sources.

Yes of course it does. Haven't tried, but looking at
xcompmgr sources, plus what you've said, it looks like
giving to my window a shaped-shadow is not going to be
an impossible task for me, or at least not one
difficult enough for not even trying. The key is in
the pixmap, for sure.

Thanks very much, I'll contact you of finding
something I cannot get through in regards of this.


>From Deron:

lg3d-core CVS

Deron It was my fault, Im sorry. I've been browsing
your project's website a bit further, and is clearly
stated that you've got to register to (at least)
download the lg3d, on the getting-started web page.

Thanks very much for pointing me directly to related
files, been looking at them, althought there's not too
much I can understand. However they've been very
useful, overall to check that your xfixes
implementation support more or less the same functions
my xserver does (cose I thought I was doing something
wrong since some of those functions worked, but no
others).

Thanks very much for you attention.

Kind Regards,
