NAME

Math::PlanePath::MathImageStaircaseAlternatingContinuous -- integer points in stair-step diagonal stripes

SYNOPSIS

 use Math::PlanePath::MathImageStaircaseAlternatingContinuous;
 my $path = Math::PlanePath::MathImageStaircaseAlternatingContinuous->new;
 my ($x, $y) = $path->n_to_xy (123);

DESCRIPTION

This path makes a staircase pattern up from the X axis to the Y axis and back again,

FUNCTIONS

See "FUNCTIONS" in Math::PlanePath for the behaviour common to all path classes.

$path = Math::PlanePath::MathImageStaircaseAlternatingContinuous->new ()

Create and return a new staircase path object.

($x,$y) = $path->n_to_xy ($n)

Return the X,Y coordinates of point number $n on the path.
