Edit Core Image Filter Code in Quartz Composer
If you want to write Core Image Filters, you will use the Core Image Filter module in Quartz Composer. Click on the Core Image Filter Module, open the Preferences Panel, go to the Settings drop down. There you got the code. Notice the additional options like “Edit Filter Function” (that will open another window with editable code). “Show Advanced Input Sample Functions” will show additional input-nodes at the module view.
There is a comprehensive documentation about the Core Image Filter programming language at the dev-site of Appel. Core Image Filters are also known as Core Image Kernels. A beginners guide is also available at the Apple Documentation.
