◆ import()

template<typename TContainer >
static TContainer DGtal::GenericReader< TContainer, 2, DGtal::uint32_t >::import ( const std::string &  filename,
unsigned int  x = 0,
unsigned int  y = 0 
)
static

Import a volume image file. For the special format h5 (you need to set WITH_HDF5 of cmake build), the default parameter datasetName needs to be updated according to the dimension if the image.

Parameters
filenamethe image filename to be imported.
xspecify the x image size to be used with raw format.
yspecify the y image size to be used with raw format.

◆ importWithColorFunctor()

const TFunctor &  aFunctor,
unsigned int  x = 0,
unsigned int  y = 0 
)
inlinestatic

Import an image file by specifying a color encoder functor (used only for color image format ppm, png, tga, bmp,jpeg) .

Template Parameters
TFunctorThe type of the functor (should verify the concept CUnaryFunctor<TFunctor, TContainer::Value, DGtal::Color > ).
Parameters
filenamethe image filename to be imported.
aFunctoran ColorRGBEncoder. The type of the functor (should verify the concept CUnaryFunctor<TFunctor, TContainer::Value, DGtal::Color > ).
xspecify the x image size to be used with raw format.
yspecify the y image size to be used with raw format.

)

Import an image file by specifying a value functor used for grayscale image.

Template Parameters
TFunctorThe type of the functor (should verify the concept CUnaryFunctor<TFunctor, unsigned char, TContainer::Value > ).
Parameters
filenamethe image filename to be imported.
aFunctorto transform input unsigned char of image value into the given image type.
xspecify the x image size to be used with raw format.
yspecify the y image size to be used with raw format.
