Detailed Description

template<class T, template< class > class CheckPolicy = GenImage_NoCheck>
class qgar::GenImage< T, CheckPolicy >

Template class for a generic image with pixels of type T.

Predefined types:

The implementation code uses some of Scott Meyers' tips from [Meyer, 1996]. See especially item #20, pages 101-104, about the return value optimization (RVO).

Warning:
The following operators and functions are not normalized:

Operators
Warning:
Using stand-alone versions of operators (operator+, operator-, operator*) is much less efficient then using assignment versions (operator+=, operator-=, operator*=). For example, an expression like: 
    res = a + b - c;
uses 2 temporary objects, one for each call to operator+ and operator-(the pixel map of the last temporary object is then copied into the pixel map of res). These considerations also apply to functional operators (see the corresponding section). To preserve efficiency, the code should be written in this way: 
    res = a;
    res += b;  // no temporary needed
    res -= c;  // no temporary needed


GenImage & operator= (const GenImage &anImg)
 Assign given image to current image.
template<template< class > class OtherCheckPolicy>
GenImage & operator= (const GenImage< value_type, OtherCheckPolicy > &anImg)
 Assign given image to current image.
template<template< class > class OtherCheckPolicy>
GenImage< value_type, GenImage_NoCheck > operator+ (const GenImage< value_type, OtherCheckPolicy > &anImg) const
 Same as function qgar::GenImage::plus.
template<template< class > class OtherCheckPolicy>
GenImage & operator+= (const GenImage< value_type, OtherCheckPolicy > &anImg)
 Same as function qgar::GenImage::plusEqual.
template<template< class > class OtherCheckPolicy>
GenImage< value_type, GenImage_NoCheck > operator- (const GenImage< value_type, OtherCheckPolicy > &anImg) const
 Same as function qgar::GenImage::minus.
template<template< class > class OtherCheckPolicy>
GenImage & operator-= (const GenImage< value_type, OtherCheckPolicy > &anImg)
 Same as function qgar::GenImage::minusEqual.
template<template< class > class OtherCheckPolicy>
GenImage< value_type, GenImage_NoCheck > operator * (const GenImage< value_type, OtherCheckPolicy > &anImg) const
 Same as function qgar::GenImage::times.
template<template< class > class OtherCheckPolicy>
GenImage & operator *= (const GenImage< value_type, OtherCheckPolicy > &anImg)
 Same as function qgar::GenImage::timesEqual.
Functional operators
Warning:
Using stand-alone versions of these functions (plus, minus, times) is much less efficient then using assignment versions (plusEqual, minusEqual, timesEqual). For example, an expression like: 
    res = a.plus(b).minus(c);
uses 2 temporary objects, one for each call to plusEqual and minusEqual (the pixel map of the last temporary object is then copied into the pixel map of res). These considerations also apply to operators (see the corresponding section). To preserve efficiency, the code should be written in this way: 
    res = a;
    res.plusEqual(b);   // no temporary needed
    res.minusEqual(c);  // no temporary needed
Operators implementation uses Scott Meyers' tips from [Meyer, 1996]: item #22, pages 107-110.

Todo:
Constructor qgar::GenImage::GenImage(AbstractPbmPlusFile&) should just work when T is instantiated by an unsigned char because function qgar::AbstractPbmPlusFile::readRow only works with rows of unsigned integers whereas the first argument of function qgar::GenImage::setRow is a pointer to a row of type T!
