[PD] [GEM] pix_write option for rendering a texture only

[cyrille henry]

ok,

what about : 

[gemhead]
|
[gemframebuffer)
|
[pix_video]
|
[pix_crop]
|
[square 4]


and: 

[gemhead]
|
[pix_texture]
|
[rectangle 4 1.5]

with a link from gemframbuffer right outlet to pix_texture right inlet

you can render whatever you wish to a texture, and using this texture on different rectangles.
why do you want to write them somewhere?
