pix_snap will not do this
pix_snap2tex as well
in both situation raw rendered object is still in the gem window
gemframebuffer might do this (there is an exaple .in textures catalog - 10.framebuffer.pd, that does almost what i need)
gemframebuffer however plugs straight to pix_texture so i can`t any pix object on the way
i posted a question about this once on the list if gemframebuffer could be modified to allow further processing and then i was answered by chris clepper
that this task would be easier to slove with a shader
