IoSurfaceRingDescriptor class final
A ring of IOSurfaces that the library allocates, for
MapHandle.attachIoSurfaceRing().
Each surface has the map's size in pixels, logical_size times the map's
scale factor, and the pixel format kCVPixelFormatType_32BGRA, which Metal
names MTLPixelFormatBGRA8Unorm.
See mln_io_surface_ring_descriptor in the
C API reference.
