/** @file dummy-image-generator.hpp
|
|
** Generator for test dummy video frames to simulate playback of rendered output.
|
|
** As of 1/2009 the render engine and source reading functions are not ready yet.
|
|
** So, in order to learn how to build up the GUI/Playback interfaces, we use
|
|
** this dummy image generator to create visible output. First implemented
|
|
** by Joel within PlaybackController, then factored out into a separate
|
|
** dummy playback service.
|
|
**
|
|
** @see gui::controller::PlaybackController
|
|
** @see proc::play::DummyPlayerService
