Introduction

The Core Image kernel language defines functions, data types, and keywords that you can use to specify image processing operations for custom Core Image filters that you write. You can also use a subset of the OpenGL Shading Language (glslang).

This document defines the symbols in the Core Image kernel language and lists the symbols in the OpenGL Shading Language that are unsupported in Core Image filters.

Any developer who wants to use the Core Image API to write custom image processing filters should read this document. Before reading this document you should be familiar with the documents listed in the See Also section.
