pix_write will only write the size specified on the inlets. So for example if you need to make a 2048x5000 size, then you have to send [2048 5000< message to the size inlet!
of course you have to draw an image of this size in order to snap it.
this can be done either with :
-a very big screen
-a virtual screen : you can define a virtual screen bigger than screen size, so you can draw a big gem windows and snap it.
-using framebuffer and snap it's content...
