KDE Digikam Image Plugins

## Introduction to Plugins for digiKam Image Editor and ShowFoto

One of the nicest things about the digiKam Image Editor is how easily its functionality can be extended, by using plugins. Plugins can manipulate images in almost any way you can imagine. Their advantage is that it is much easier to add a capability to the Image Editor by writing a small plugin than by modifying the Image Editor core. Many valuable plugins have C++ source code that amounts to 100-200 lines only or so.

A core plugin is included in the main digiKam distribution, and it is installed automatically along with the digiKam Image Editor. It provides some important features like Red Eye Reduction tool and Auto-Levels. The digiKam Image Plugins package adds more functions as new plugins. They add extra menus, shortcuts, and extentions to the image editor with features like new filters, special effects, and advanced tools.
