NAME

Imager::LineTrace::Algorithm - Line trace algorithm

SYNOPSIS

use Imager::LineTrace::Algorithm;

my @pixels = Imager::LineTrace::Figure->new(
    [ 1, 1, 1 ],
    [ 1, 0, 1 ],
    [ 1, 1, 1 ]
);

my %args = ( ignore => 0 );
my $figures_ref = Imager::LineTrace::Algorithm::search( \@pixels, \%args );

DESCRIPTION

Trace algorithm for Imager::LineTracer.

RETURN DATA

# $figures_ref is ARRAY reference.
my $figures_ref = Imager::LineTrace::Algorithm::search( \@pixels, \%args );

# $figure_ref is HASH reference.
my $figure_ref = $figures_ref->[0];

# $figure_ref->{points} is ARRAY reference.
foreach my $point (@{$figure_ref->{points}}) {
    printf( "x = %d, y = %d\n", $point->[0], $point->[1] );
}

# Traced pixel value.
print $figure_ref->{value}, "\n";

# Figure is closed.
print $figure_ref->{is_closed}, "\n";
