- Obsolete: Types with embedded references are not supported in this version of your compiler.
Scoped access to the raw bytes of the rows of a frame, valid only during a ImageFrame.ProcessPixelBytes callback.
[Obsolete("Types with embedded references are not supported in this version of your compiler.", true)]
public readonly ref struct PixelBytesAccessorRemarks
Each row is contiguous and contains exactly PixelBytesAccessor.RowLength bytes of visible pixels; 16-bit components are in native endianness. The accessor is bound to the lease of the callback: once the callback returns, PixelBytesAccessor.GetRowSpan throws an InvalidOperationException. A default instance has no rows.
