Fx protocol defines the methods a filter plug-in must implement to render output.
- FxPlug 3.1+
Filters are a type of plug-in that takes an input image, modifies it, and produces an output image. This differs from generators which create output without having any input image, and transitions which take two images and move between them.
Filters can be used for color manipulations, distortions, timing changes, and much more.
Fx protocol derives from
Fx protocol and adds several other methods, including the
render method which is where a plug-in actually renders its effect.
