Detailed Description

template<typename TImageContainer>
class DGtal::ImageFactoryFromImage< TImageContainer >

Aim: implements a factory to produce images from a "bigger/original" one according to a given domain.

Description of template class 'ImageFactoryFromImage'

Template Parameters

TImageContainer

an image container type (model of CImage).

The factory images production (images are copied, so it's a creation process) is done with the function 'requestImage' so the deletion must be done with the function 'detachImage'.

The update of the original image is done with the function 'flushImage'.

Examples

images/exampleImageFactoryFromHDF5.cpp, and images/exampleTiledImage.cpp.
