Member Function Documentation

FromDRM()

static constexpr wl_shm_format FromDRM ( RFormat  format )

inlinestaticconstexprnoexcept

Converts a DRM (FourCC) format to the equivalent wl_shm_format.

The XRGB8888 and ARGB8888 formats are mapped to their dedicated wl_shm enumerators; all other formats share the same numeric value and are cast through directly.

ToDRM()

static constexpr RFormat ToDRM ( wl_shm_format  format )

inlinestaticconstexprnoexcept

Converts a Wayland wl_shm_format to the equivalent DRM (FourCC) format.

The XRGB8888 and ARGB8888 enumerators are mapped to their DRM FourCC counterparts; all other formats share the same numeric value and are cast through directly.
