NAME

App::MathImage::NumSeq::PlanePathDelta -- sequences of coordinates from PlanePath modules

SYNOPSIS

use App::MathImage::NumSeq::PlanePathDelta;
my $seq = App::MathImage::NumSeq::PlanePathDelta->new (planepath => 'SquareSpiral',
                                                  delta_type => 'X');
my ($i, $value) = $seq->next;

DESCRIPTION

This module gives coordinates from a Math::PlanePath as a sequence. There's various choices of what coordinate to take from the path, such as X, Y, radius, dX, dy, etc.

FUNCTIONS

$seq = App::MathImage::NumSeq::PlanePathDelta->new (key=>value,...)

Create and return a new sequence object.

$bool = $seq->pred($value)

Return true if $value is a happy number, meaning repeated sum of squares of its digits reaches 1.
