Constructors

OpenCvSafeHandle()

Initializes a new instance of the OpenCvSafeHandle class that owns the handle.

OpenCvSafeHandle(bool)

Initializes a new instance of the OpenCvSafeHandle class.

OpenCvSafeHandle(nint, bool)

Initializes a new instance of the OpenCvSafeHandle class with an existing handle.

Properties

IsInvalid

When overridden in a derived class, gets a value indicating whether the handle value is invalid.

Null

A non-owning handle wrapping a null native pointer. Pass this for an optional SafeHandle-typed P/Invoke argument (e.g. a mask) when the caller has none, instead of overloading the parameter type with a plain nint.

Methods

RunPostReleaseAction()

Runs and clears the registered post-release cleanup without allowing an exception to escape the SafeHandle critical-finalizer path.
