I tested your patch here on an Intel Mac and it works like I think it should work.  Two of the layers are partially transparent based on the individual R G and B values.  Can you post a screen capture of the working and non-working output?

hi,

I am finding that gem is doing things very differently in two versions. The
attached patch is slightly simplified from what I am running but the essence
is running 3 versions of the same movie on 3 'screens' using [pix_threshold]
and [pix_alpha] to selectively hide elements of the pictures at the front.
This works fine when I use pd-extended0.38 When I try it with
pd-extended0.39 (from http://at.or.at/hans/pd/installers.html ) it doesn't
work. The pictures on the front 'screens' are all turned blueish but the
selections aren't removed.
I am running this on an intel Mac OSX10.4
I would be happy to stick with 0.38 but other things aren't working correctly
with it, and I can't even run two versions in parallel because hans' version
handles libraries internally, and gets confused when there is a preference
file like the older version wants :(

Any ideas?

Thanks
Oded
