Function Documentation

template<class T_or_RGB >

std::ostream& operator<<	(	std::ostream &	os,
		const Image< T_or_RGB > &	img
	)			[inline]

Write the pixel values of the Image in a nice human-readable format.

Caveat emptor: it may only be "nice" if the img has a fairly small number of elements, so that one row of the image fits in one row of text. This format is not intended to generate a representation that can be re-parsed by the computer to recreate the original image.

template<class T >

void readImageFromStream	(	std::istream &	is,
		Image< T > &	img
	)			[inline]

Read img from "is" which has been written with writeImageToStream before.

template<class T >

void writeImageToStream	(	std::ostream &	os,
		const Image< T > &	img
	)			[inline]

Write img to to "os", one line of the image into one line of text.

This is only useful for rather small images!
