Einhugur macOS Bridge plugin.

EinhugurCoreBridge.CGImage Class

Representation of macOS CGImage object.

The object has been wrapped to make it easy to us NSImage with Xojo API’s and Einhugur API’s.

The object can be used by it self, or with CGImage coming from Declare in Xojo, or with CGImage coming from 3rd party plugin (if they can provide Integer based handle to the CGImage).

The object will be automatically released like any other Xojo object. Do not manually use the Release method unless you have done something externally to the CGImage, with other plugin or declares that might call for release.
