It provides a compact and powerful image-processing architecture that allows developers to build unique, hardware-accelerated or CPU-based effects with customized user interfaces and onscreen controls. FxPlug primarily utilizes Objective-C protocol definitions. Developers implement these protocols in Objective-C, Objective-C++, or Swift to create plug-ins. Host applications provide capabilities for protocols with the API suffix, while plug-in developers implement the remaining protocols. FxPlug 4 introduced fully out-of-process plug-ins, enhancing security and offering flexibility in rendering technologies (OpenGL, Core Graphics, Core Image, Metal). This version also includes the `FxTileableEffect` API for efficient rendering of specific output portions (tiles). ``` === COMPLETE CONTENT === This response contains all available snippets from this library.
