Detailed Description

Support for the debug "surface to screen" coordinate translation interface.

Note
For shells which do surface transformations the default implementation will return incorrect results.

§ surface_to_screen()

virtual geometry::Point mir::scene::CoordinateTranslator::surface_to_screen ( std::shared_ptr< frontend::Surface surface,
int32_t  x,
int32_t  y 
)
pure virtual

Translate a surface coordinate into the screen coordinate space.

Parameters
[in]surfaceA frontend::Surface. This will need to be dynamic_cast into the scene::Surface relevant for the shell.
[in]x,yCoordinates to translate from the surface coordinate space
Returns
The coordinates in the screen coordinate space.
Exceptions
Astd::runtime_error if the translation cannot be performed for any reason.
Note
It is acceptable for this call to unconditionally throw a std::runtime_error. It is not required for normal functioning of the server or clients; clients which use the debug extension will receive an appropriate failure notice.
