[PD] GEM: pix_coordinate: how to use (was GEM: possibility to split gemframebuffer or gemlist?)

Wed Mar 31 21:27:40 CEST 2010

Hi again,

the patch Jack sent me was what I was looking for. However I have some  
troubles with the pix_coordinate object. Currently the final image is  
split into two rectangles  that sit left to right next to each other,  
but what I actually need now is from top to down.

I don't know how to manipulate pix_coordinate. I have no idea how to  
use them as they are no XYZ coordinates. How can I achieve what I need?

Thanks a lot & best

Johannes
