5.5.2.1 Input

 
The Input class is the parent class for all the Input modules in the system, and so it is conceptually abstract -- it defines its destructor, the getImage() and getDimension() methods as virtual. However, it provides a minimal null implementation of an Input module, which always returns NULL from getImage() and always returns a dimension of \( 10\times 10 \) pixels from getDimension().

This module is the default when no input module is specified, has the valid name of default, and takes no parameters.
