This document introduces you to the Camera Plugin Support API.
This API is implemented as an Ecom plug-in.
Camera Plugin Support Library Details
The DLL that provides the functionality and the library to which your code must link is identified below.
When a new camera object is required, the Ecam library requests a camera plug-in from the Ecom framework. When more than one ROM based plug-ins have been registered on the platform, the one with the highest version defined in its resource file is selected.
Symbian version of the plug-in is a stub intended for replacement by an alternate implementation.
ECam implementation provides static information about camera support to the client, by deriving from CcameraInfoPlugin() . Method Ccamera::CamerasAvailable() is implemented through concrete implementation of CcameraInfoPlugin virtual method. Implementers need to register support for the interface KuidOnboardCameraPlugin in their resource file.
All cameras are Ecom plug-ins sub-classed from CcameraPlugin class and register support for the interface KuidOnboardCameraPlugin in their resource file. The key classes that make up the Camera Plug-in Support API is CcameraPlugin .
The current implementation of the camera expects cameras to be implemented as Ecom plug-ins. The ROM plug-in with the highest version is selected at instantiation phase. The plug-in implements CCamera interface, defined in ECam.h .
