context
Creates a context without a specific rendering destination, using default options.
Declaration
+ (CIContext *) context;Return Value
A new Core Image context.
Discussion
If you create a context without specifying a rendering destination, Core Image automatically chooses and internally manages a rendering destination based on the current device’s capabilities. You cannot use a context without an explicit destination for the methods listed in Drawing Images. Instead, use the methods listed in Rendering Images.
To specify additional options for the context, use the contextWithOptions: method instead.
