Detailed Description

template<typename TImageContainer, typename TImageFactory, typename TReadPolicy, typename TWritePolicy>
class DGtal::ImageCache< TImageContainer, TImageFactory, TReadPolicy, TWritePolicy >

Aim: implements an images cache with 'read and write' policies.

Description of template class 'ImageCache'

Template Parameters

TImageContainer	an image container type (model of CImage).
TImageFactory	an image factory type (model of CImageFactory).
TReadPolicy	an image cache read policy class (model of CImageCacheReadPolicy).
TWritePolicy	an image cache write policy class (model of CImageCacheWritePolicy).

The cache provides 3 functions:

read : for getting the value of an image from cache at a given position given by a point only if that point belongs to an image from cache
write : for setting a value on an image from cache at a given position given by a point only if that point belongs to an image from cache
update : for updating the cache according to the read cache policy
