- sdl_pixel_format(?Format:atom, ?Value:integer) is nondet
- Enumerate the SDL pixel formats and their exact bit values. Each
format is a Prolog atom linked to its SDL 32-bit pixel format value.
The user-facing format atoms are:
argb8888,rgba8888,bgra8888,abgr8888xrgb8888,xbgr8888,rgbx8888,bgrx8888argb32,rgba32,bgra32,abgr32xrgb32,xbgr32,rgbx32,bgrx32rgb24,bgr24rgb565,bgr565
The *8888, *24 and *565 formats are platform-independent. The *32 aliases are platform-dependent: they resolve to the concrete 8888 formats according to the CPU byte order of the running platform, as shown in the values below (valid for little-endian builds). The pack ships as a unit (.pl + .so built for the same platform), so this is always consistent.
