NAME

Color::Similarity - common interface to different Color::Similarity::* modules

SYNOPSIS

  use Color::Similarity;

  my $package = ...; # for example Color::Similarity::HCL

  my $s = Color::Similarity->new( $package );

  my $d1 = $s->distance( [ $r1, $g1, $b1 ], [ $r2, $g2, $b2 ] );

METHODS

new

  my $s = Color::Similarity->new( $package );

Constructs a new Color::Similarity object wrapping the given $package. The module will not try to load the package, so the caller must have done it already.

distance_rgb

  my $d = $s->distance_rgb( [ $r1, $g1, $b1 ], [ $r2, $g2, $b2 ] );

Converts the RGB triplets to the appropriate representation (usually a different colorspace) and computes their distance.

convert_rgb

  my $c = $s->convert_rgb( $r, $g, $b );

Converts the given RGB triplet to a representation suitable for passing it to distance.

distance

  my $d = $s->distance( $c1, $c2 );

Computes the distance between two colors already in an appropriate representation (either using convert_rgb or by alternate means).
