Struct IoSurfaceRingDescriptor

Namespace

Maplibre.NativeFfi

Assembly

Maplibre.NativeFfi.dll

A ring of IOSurfaces that the library allocates, for MapHandle.AttachIoSurfaceRing().

public readonly record struct IoSurfaceRingDescriptor : IEquatable<IoSurfaceRingDescriptor>

Implements

IEquatable<IoSurfaceRingDescriptor>

Inherited Members

ValueType.Equals(object)

ValueType.GetHashCode()

ValueType.ToString()

object.Equals(object, object)

object.GetType()

object.ReferenceEquals(object, object)

Remarks

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.
