Editing Images
With Image Tricks, you can use custom or third party quartz compositions. Image Tricks looks for them in the following folder:
~/Library/Compositions/
“~” means the user's Home folder.
To make new quartz compositions listed in Image Tricks, place them in the specified folder.
To be compatible with Image Tricks, a composition should conform to Image Filter. To verify this, choose the Editor > Edit Protocol Conformance menu in the Quartz Composer application.
