Overview
The CIPlugInRegistration protocol defines a method for loading Core Image image units. The principal class of an image unit bundle must support this protocol.
Instance Methods
load:
Loads and initializes an image unit, performing custom tasks as needed. (required)
- (BOOL)load:(void *)host
Parameters
- host
Reserved for future use.
Return Value
Returns true if the image unit is successfully initialized
Discussion
The load method is called once by the host to initialize the image unit when the first filter in the image unit is instantiated. The method provides the image unit with an opportunity to perform custom initialization, such as a registration check.
Availability
- OS X v10.4 and later.
