Detailed Documentation

Fields

struct tw_surface_buffer buffer

the tw_surface::buffer is used to present; should stay available from imported to destroy of the surface

struct wl_list links[MAX_VIEW_LINKS]

many types may need to use one of the links, eg: backend_ouput, layer, compositor, input. Plane.

struct tw_mat3 transform

map from (-1,-1,1,1) to global coordinates in a Y-down coordinate system

unnamed-struct geometry

transform of the view
