Detailed Description

template<typename T, int dim = 2>
class Imagine::Image< T, dim >

Image of variable size, dimension and pixel type. Memory is reference counted, i.e.:

a=b results in a and b sharing the same memory
the last object using memory frees it when it dies
use clone() when this sharing is not desired

Parameters

T	pixel type
dim	dimension (default=2)

Examples:: Images/test/test.cpp.

Member Typedef Documentation

◆ scalar_type

template<typename T, int dim = 2>

typedef PixelTraits<T>::scalar_type Imagine::Image< T, dim >::scalar_type

This is useful for images whose pixel type T is itself composed, like an FVector<U>, RGB<U>, or Color, in which case scalar_type is U (byte for Color).

◆ norm2

template<typename T, int dim = 2>

scalar_type norm2 ( const Image< T, dim > & I )

friend

Squared Euclidean norm of pixel values, i.e the sum of the squared norm of pixels. Beware of overflow.

Parameters

I argument

Returns: squared norm.

◆ operator*

template<typename T, int dim = 2>

Image operator*	(	scalar_type	s,
		const Image< T, dim > &	I
	)

friend

Multiplication by a scalar

Parameters

s	scalar factor
I	image

Returns: result

O=2*P; // scalar * image

◆ operator+

template<typename T, int dim = 2>

Image operator+	(	T	v,
		const Image< T, dim > &	I
	)

friend

Addition of a constant

Parameters

v	constant to be added to I
I	image

Returns: result

O=RGB<double>(1.,2.,3.)+P; // constant + image

◆ operator-

template<typename T, int dim = 2>

Image operator-	(	T	v,
		const Image< T, dim > &	I
	)

friend

Substraction of a constant

Parameters

v	constant from which I is to be substracted
I	image

Returns: result

O=RGB<double>(1.,2.,3.)-P; // constant - image

◆ sum

template<typename T, int dim = 2>

T sum ( const Image< T, dim > & I )

friend

Sum of pixel values. Beware of overflow.

Parameters

I argument

Returns: sum

cout << sum(Jd) << ' ' << sum(Jcd) << endl; // sum of pixels
