I would like to do at runtime in a program, what Quartz Composer does with the Core Image Filter patch: Compiling a CIFilter inside Quartz Composer. Quartz Composer has a patch that takes the text of the CIFilter kernel, with which it creates the CIFilter.
Do we have access to this in the public API?
The solution is to apply a kernel, and the kernel is created with the + kernelsWithString: class method.
