gf_draw_blit2()

If your current process is not the process that created the surface, you
need to somehow obtain the sid of the desired surface
(gf_surface_get_info() can provide that data on the "server" side), then
send it to your current process.  The current process can then passively
attach with gf_surface_attach_by_sid().  Now wait for h/w idle, then do
the blit.

Does anyone know of a way to get the pixel data from a surface back out
of the surface into other memory?  This could be useful for me to create
a screenshot of the current surface attached to the layer or do
computations and analysis of the framebuffer.

I am using a full software implementation with the devg-imx25.so driver
on an i.mx25 PDK development kit.

Thanks for the help.

Hi John,

Did you ever find an answer to this?  Looks like I'm following down the same road now.

Thanks,
Devan
