Developing with Core Image |
 | | When an Image Unit is loaded and configured with an image (or images), as well as any needed parameters that define the settings that the Image Unit can take, pixels are fetched from the input image by a sampler object that handles any needed coordinate transformation and scaling. |
 | | Since Image Units execute in near real-time, and only on the pixels that need to be processed, it is possible to keep the original state of the source images and reprocess the displayed pixels as needed. |
 | | And finally, Image Units defines a new way to share image processing capabilities between applications and paves the road for a marketplace of plug-ins that can be used by any image processing application on the system that supports Core Image. |
