Detailed Description

template<typename TContainer, int Tdim = TContainer::Point::dimension, typename TValue = typename TContainer::Value, typename TFunctor = functors::Identity>
struct DGtal::GenericWriter< TContainer, Tdim, TValue, TFunctor >

Aim: Provide a mechanism to save image (2D or 3D) into file with the best saver loader according to an filename (by parsing the extension).

Description of template class 'GenericWriter'

The typical use is very simple:

• First include the header of the generic reader (and StdDefs) and define image type:

  #include "DGTal/io/readers/GenericWriter.h"
  #include "DGtal/helpers/StdDefs.h"
  typedef DGtal::ImageContainerBySTLMap<DGtal::Z3i::Domain, unsigned char> Image3D;
  typedef DGtal::ImageContainerBySTLMap<DGtal::Z2i::Domain, unsigned char> Image2D;

• After contructing and filling an image (anImage2D or anImage3D), just save it with:

  anImage3D >> "aFilename.pgm3d";
  anImage3D >> "aFilename.vol";
  anImage2D >> "aFilename.pgm";

  Note

  the stream operator hide a default functor (c++ cast to a given type) and if the user want to control the cast he can used the exportFile function (see below).

  Template Parameters

  TContainer	the container (mainly an ImageContainer like ImageContainerBySTLVector or ImageContainerBySTLMap).
  Tdim	the dimension of the container (by default given by the container).
  TValue	the value type of data contained in the image (by default given by the container)
  TFunctor	a functor type to apply image transformation before saving the image (by default set to functors::Identity).
