The Sample App
The sample app for this chapter is called ImagePlayground. The app demonstrates selecting an image from the device’s photo library or acquiring an image from the camera to be used as a source image, which the app then resizes to a smaller size. The user can select and chain filters to apply to the source image to alter how it looks, with the effect of each filter displayed in a table alongside the name of each selected filter. The filter selection process demonstrates how Core Image filters are organized into categories, and enables the user to customize a selected filter and preview its effect.
