I have some conceptual questions:
a) What is the relationship between layers and screens.
I see one can enumerate layers from a screen interface, and given a
layer it's possible to retrieve its screen.
=> Relationship Screen 1 : N Layers.
b) How would one set a video mode for an arbitrary screen?
For IDirectFB::SetVideoMode: The primary surface is attached to a
layer and this is present on a given screen; it is that screen that is
affected in this case. Correct?
But is it possible to set the mode directly for any screen? There are
methods via IDirectFBScreen to set mixer, encoder and output
configurations, but I don't see any explicit resolution or timing
structure.
Or is this implicit from the layer dimensions - which layer? Is it
the 'primary layer' on each screen?
Regards,
Jason Barstow.
