	Example: irange r(0,2,10); r+=3; Then r is 3,5,7,9,11,13.
irange &	operator-= (const int &i)
	Other inc and dec operators are analogous to +=.

Detailed Description

Represents a range of integers with constant spacing, e.g. 2, 5, 8, .., 32.

iranges are used chiefly to index picture_of_ints and colour_picture_of_ints to define subimages.

Constructor & Destructor Documentation

clip::irange::irange (  const int &  first, const int &  second, const int &  last )

irange r(0,1,7); means r represents the range of ints 0,1,2,3,4,5,6,7. Similarly, irange s(3,7,31); means s represents 3,7,11,15,19,23,27,31.

Member Function Documentation

int clip::irange::operator[] (  const int &  i  )  const

Example: If we declared irange r(0,2,10); then the numbers in the range are 0,2,4,6,8,10 and r[3] equals 6.
