Detailed Description

Deep image plane class. Represents deep data on certain channels for a certain box. The actual deep data is stored in a separate reference-counted structure, so that copying is cheap. This class is read-only. If you wish to write to a DeepPlane, use the DeepOutputPlane subclass.

Constructor & Destructor Documentation

DD::Image::DeepPlane::DeepPlane	(	DD::Image::ChannelSet	channels,
		DD::Image::Box	box,
		DeepPixel::Ordering	ordering = DeepPixel::eUnordered
	)			[protected]

Create an empty deep plane for a given set of channels and bounding box. addPixel() or addHole() must be called for each position in the box for the object to be valid for returning from doDeepEngine().
