Yep, that's why Cyrille says that you can use [pix_snap] or [pix_snap2tex].
like in exemple 07.texture/07.feedback
Or you can also use [gemframebuffer].
like in exemple 10.glsl/06.framebuffer and shader, but removing the shader.
With that, you can capture a certain part of your last frame and add it to your new. But the result could be not very nice.
why?

yes, but my problem is : I need to emulate single buffer on double buffer, i need to use double buffer because i work with iterations using repeat or until objects, and in single buffer with metro this iterators are so so so slow, almost "2" fps.
wow, it's strange that it is slower in single buffer. do you have a test patch that demonstrate this?
i want donŽt clear the image buffer when is drawed the new buffer, like an accumulation...but using double buffer!!....is possible???...in single buffer is easy, but with iterators....no way.
i don't understand why iterators can't work in single buffer.

thanks for your patience.

hello,
is possible in gem to change between single buffer and double buffer without destroy gemwindow??
no
or dont`t clear buffer(background image) in double buffer???
not really, but you can sna2tex and draw the last image on every frame.
you can also easily emulate 2 buffer while in single buffer, using metro to bang gemhead and clean windows / clear Z buffer.
Cyrille
thanks a lot!!!
