BOOST_CONCEPT_ASSERT()

template<typename TContainer, typename TValue>

DGtal::GenericReader< TContainer, 3, TValue >::BOOST_CONCEPT_ASSERT

(

(concepts::CImage< TContainer >)

)

import()

template<typename TContainer, typename TValue>

TContainer DGtal::GenericReader< TContainer, 3, TValue >::import ( const std::string & filename, unsigned int x = 0, unsigned int y = 0, unsigned int z = 0 )

static

Import a volume image file. For the special format of raw image, the default parameter x,y, z need to be updated according to the dimension if the image.

Parameters

filename	the image filename to be imported.
x	the size in the x direction.
y	the size in the y direction.
z	the size in the z direction.

importWithColorFunctor()

TContainer DGtal::GenericReader< TContainer, Tdim, TValue >::importWithColorFunctor ( const std::string & filename, const TFunctor & aFunctor, std::vector< unsigned int > dimSpace = std::vector<unsigned int>() )

inlinestatic

Import a volume nd image file by specifying a value functor.

Template Parameters

TFunctor

The type of the functor (should verify the concept CUnaryFunctor<TFunctor, TValue , TContainer::Value > )

Parameters

dimSpace	a vector containing the n dimensional image size.
filename	the image filename to be imported.
aFunctor	an ColorRGBEncoder. The type of the functor (should verify the concept CUnaryFunctor<TFunctor, TContainer::Value, DGtal::Color >).

Parameters

filename	the image filename to be imported.
aFunctor	an ColorRGBEncoder. The type of the functor (should verify the concept CUnaryFunctor<TFunctor, TContainer::Value, DGtal::Color > ).
x	x
y	y
