offscreen context - physical address

Hi,

is it possible to retrieve more information about a photon offscreen context?

We need the physical memory address and the line pitch, so we can instruct some hardware to write to this area.

TIA

Hi Peter,

I spoke with one of the developers and here is the information your
looking for:

You can get the Pitch from the offscreen context structure:

osc->pitch

a physical address from the pointer can be gotten from mem_offset()

Hope this helps
Regards
Brenda
