Overview

Package coreimage provides a fluent Go API over the macOS CoreImage framework.

Construction

New… functions create objects; each With… method sets one property and returns its receiver, so configuration calls chain. A <Type>FromID constructor adopts an Objective-C object obtained elsewhere.

Lifecycle

A wrapper releases its Objective-C object automatically once the garbage collector finds it unreachable. Call Release to relinquish the reference deterministically (for objects holding scarce resources); Release is idempotent, and afterwards the wrapper's methods are no-ops returning zero values.

Types

Each base type below lists the concrete types you construct and pass where the base is accepted:
