SYNOPSIS
use Math::Image;
my $i = new Math::Image; # Make a new Image
my $i = new Math::Image(1,2,3);DESCRIPTION
Default value

Summary
'""' => Returns a string representation of the vector.METHODS
new(w, h, components, array)
w is the width of the image. h is height of the image. comp is the number of components of the image, 1 for greyscale, 2 for greyscale+alpha, 3 for rgb, 4 for rgb+alpha). All these values are scalar. Array is an array ref containing the w*h values for the pixels of the image.
Format of each pixel:
Comp. byte[0] byte[1] byte[2] byte[3]
------- ---------- ---------- ----------- -----------
1 intensity1 intensity2 intensity3 intensity4
2 intensity1 alpha1 intensity2 alpha2
3 red1 green1 blue1 red2
4 red1 green1 blue1 alpha1Examples:
$v = new Math::Image();
$v = new Math::Image( 2, 2, 4, [ 0xABCDEFAB, 0xABCDEFAB, 0xABCDEABF, 0xABCDABEF ] );copy

getValue
Returns the value of the image (width, height, components, array) as a 4 components array.
($width, $height, $components, $array) = $i->getValue;
@i = $i->getValue;getWidth

toString
Returns a string representation of the image. This is used to overload the '""' operator, so that image may be freely interpolated in strings.
my $i = new Math::Image(0, 0, 0);
print $c->toString; # "0 0 0"
print "$c"; # "0 0 0"SEE ALSO
