NAME ^

Color::Similarity::RGB - compute color similarity using the RGB color space

SYNOPSIS ^

  use Color::Similarity::RGB qw(distance rgb2rgb distance_rgb);
  # the greater the distance, more different the colors
  my $distance = distance( [ $r1, $g1, $b1 ], [ $r2, $g2, $b2 ] );

DESCRIPTION ^

Computes color similarity using the RGB color space and Euclidean distance metric.

FUNCTIONS ^

distance

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

Synonim for distance_rgb, for consistency with other Color::Similarity::* modules.

rgb2rgb

  [ $r, $g, $b ] = rgb2rgb( $r, $g, $b );

Silly "conversion" function, for consistency with other Color::Similarity::* modules.

distance_rgb

  my $distance = distance_rgb( [ $r1, $g1, $b1 ], [ $r2, $b2, $b2 ] );

Computes the Euclidean distance between two colors in the RGB color space.

SEE ALSO ^
