SYNOPSIS

use Math::Image;
my $i = new Math::Image;  # Make a new Image

my $i = new Math::Image(1,2,3);

DESCRIPTION

Default value

0 0 0

OPERATORS

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      alpha1

Examples:

$v = new Math::Image();
$v = new Math::Image( 2, 2, 4, [ 0xABCDEFAB, 0xABCDEFAB, 0xABCDEABF, 0xABCDABEF ] );

setValue(width, height, components, array)

setWidth(width)

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

Not implemented yet.

getHeight

Not implemented yet.

getComponents

Not implemented yet.

getArray

Not implemented yet.

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"
