Variants

Destroy

unbind from the cropping and scaling interface

Informs the server that the client will not be using this protocol object anymore. This does not affect any other objects, wp_viewport objects included.

This is a destructor, once received this object cannot be used any longer.

GetViewport

extend surface interface for crop and scale

Instantiate an interface extension for the given wl_surface to crop and scale its content. If the given wl_surface already has a wp_viewport object associated, the viewport_exists protocol error is raised.

Fields of GetViewport

id: NewResource<WpViewport>surface: Resource<WlSurface>
