method	Vision	MBS MacFrameworks Plugin	25.2	✅ Yes	❌ No	❌ No	✅ Yes	All

Creates a high-resolution image where everything becomes transparent black, except for the instances you specify.

instances: The collection of instances.
requestHandler: The image request callback.
cropResult: A Boolean value that indicates whether to crop the image to the smallest rectangle that contains all instances.
error: On output, an error object that describes why the method failed, or nil if no error occurred. If you are not interested in the error information, pass nil for this parameter.

Returns the pixel buffer that contains the image. On failure, this method returns nil.
Result is an object of CVPixelBufferMBS class.
