Description of class 'PPMReader'

Template Parameters
TImageContainerthe type of the image container
TFunctorthe type of the functor to transform the source image color into scalar value. This functor should follows the concept CUnaryFunctor<TFunctor, DGtal::Color, TImageContainer::Value>

Main method to import a PPM (24bit, 8bits per channel) into an instance of the template parameter ImageContainer.

Parameters
aFilenamethe file name to import.
aFunctorthe functor that from a given color return it associated code (by default set to BasicColorToScalarFunctors::ColorRGBEncoder).
topbotomOrderif true, the point of coordinate (0,0) will be the bottom left corner image point (default) else the center of image coordinate will be the top left of the image (not usual).
Returns
an instance of the ImageContainer.
