[PD] GEM: Change buffer without destroying?

[David Sabine]

Hello,

I'm using GEM to render a number of different visual effects and ONE of those structures requires a gemwin buffer value of "1" while all others work best at "2".

These structures don't need to render simoultaneously - but it would be nice.

However, when I try to change the buffer size by sending the value to gemwin, the GEM window starts acting erratically.  Hence, I'm guessing that the buffer size can only be changed after destroying the gem window before creating a new one (am i right to assume this?)

So the question is: How can I change the buffer size of the gem window without destroying the window?

sub-question: The gemlist that I'm having difficulty with is similar to gemPixDataSimple.pd from the GEM examples.  Why does that type of structure require "buffer 1"?  How can that example patch be modified to work with "buffer 2"?

Thanks...
Dave S
