Detailed Description

template<typename TImageContainer, typename TNewDomain, typename TFunctorD, typename TNewValue, typename TFunctorV>
class DGtal::ConstImageAdapter< TImageContainer, TNewDomain, TFunctorD, TNewValue, TFunctorV >

Aim: implements a const image adapter with a given domain (i.e. a subdomain) and 2 functors : g for domain, f for accessing point values.

Description of template class 'ConstImageAdapter'

This class is (like Image class) a lightweight proxy on any models of CConstImage. It uses a given Domain (i.e. a subdomain) but work directly (for accessing process) thanks to an alias (i.e. a pointer) on the original Image given in argument.

ConstImageAdapter class is also a model of CConstImage.

Caution :

• the type of value of Point for the ConstImageAdapter Domain must also be the same than the type of value of Point for the original ImageContainer.

Template Parameters

TImageContainer	an image container type (model of CConstImage).
TNewDomain	a domain.
TFunctorD	the functor g that transforms the domain into another one
TNewValue	the type of value return by the functor f.
TFunctorV	the functor f that transforms the value into another one during reading process

The values associated to accessing the point values are adapted with a functor g and a functor f given at construction so that operator() calls f(img(g(aPoint))), instead of calling directly operator() of the underlying image img.

Here is the construction of a simple ConstImageAdapter that is a thresholded view of the initial scalar image:

  typedef ConstImageAdapter<Image, Domain, functors::Identity, bool, DGtal::functors::Thresholder<Image::Value> > ConstImageAdapterForThresholderImage;
  DGtal::functors::Thresholder<Image::Value> t(127);
  ConstImageAdapterForThresholderImage thresholderImage(image, domain, df, t);

NB: the underlying image as well as the 2 functors are stored in the adapter as aliasing pointer in order to avoid copies. The pointed objects must exist and must not be deleted during the use of the adapter

Examples:

geometry/volumes/distance/exampleFMM3D.cpp, images/exampleConstImageAdapter.cpp, images/exampleRigidtransformation2d.cpp, images/exampleRigidtransformation3d.cpp, images/extract2DImagesFrom3D.cpp, images/extract2DImagesFrom3DandVisu.cpp, images/extract2DSlicesImagesFrom3D.cpp, images/imageBasicSubsampling.cpp, io/viewers/viewer3D-8bis-2Dimages.cpp, and tutorial-examples/2DSliceImageFromVol.cpp.
