inline

Render element if it passes the filtering procedure. This method should be used for elements which can be used in scope of rendering algorithms. E.g. elements of groups during recursive rendering. If render filter is null, pure rendering is performed.

Parameters

theWorkspace	[in] the rendering workspace.
theFilter	[in] the rendering filter to check whether the element should be rendered or not.

Returns

True if element passes the filering check and is rendered.
