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().

References _sharedData.

DD::Image::DeepPlane::DeepPlane

(

)

Create an uninitialised plane.

References _sharedData.

DD::Image::DeepPlane::DeepPlane

(

const DeepPlane &

other

)

Construct one deep plane based on another. The data is shared.

References _box, _channels, _ordering, and _sharedData.

DD::Image::DeepPlane::~DeepPlane

(

)

Destroy this plane.
