◆ StartLayer()

void IGraphics::StartLayer	(	IControl *	pOwner,
		const IRECT &	r,
		bool	cacheable = `false`
	)

Create an IGraphics layer.

Switches drawing to an offscreen bitmap for drawing IControl* pOwner The control that owns the layer

Parameters

r	The bounds of the layer within the IGraphics context
cacheable	Used to make sure the underlying bitmap can be shared between plug-in instances
