It is taking tasks dispatched by the RenderJob (RenderJobImp) and renders them. The RenderThread returns it's results incrementally (asynchronosly) via the ImageWriter Callback object provided by the RenderJob. On terminated the ImageWriter::finishWriter is called and the RenderJob either let the thread terminate or dispatches another rendering task to the thread. Member Function Documentation RenderThread * RenderThread::getInstance ( ) throw (WrongContextError) [static]   getInstance returns the RenderThread instance of the current thread execution context. A WrongContextError is thrown if the current thread isn't a RenderThread. Reimplemented from ContextThread. void RenderThread::getRenderTask ( Area & area, Strategy *& rpStrategy )   Query the currently prepared or performed rendering task. Parameters: area   the area to render rpStrategy   the strategy to use to render this area void RenderThread::setRenderParameter ( long nWidth, long nHeight, int nFormat )   Set the initial rendering parameters. Parameters: nWidth   total width of the whole image the rendering takes place on nHeight   total height of the whole image the rendering takes place on nFormat   the pixelformat the output should be (e.g. 8/16 Bit per channel, alpha channel settings) void RenderThread::setRenderTask ( const Area & area, Strategy * pStrategy )   Set the render task to do. Parameters: area   the area to render pStrategy   the strategy to use to render this area The documentation for this class was generated from the following file: RenderThread.h
