Multiple GD Objects	Can't Post

I'm working on some code which handles 10 images. To create an image object with GD you use:

Code

$im1 = new GD::Image($width,$height,1);

However, since I'm using 10 images, I don't want to write:

Code

$im1 = ... 
$im2 = ... 
$im3 = ...

So I used a for loop and:

Code

${"im".$i} = new GD::Image($width,$height,1);

Where $i would be the image number, however this doesn't work.

What would be a better way of handling multiple GD objects?

Thank You :)

Use an array.

Code

my @image; 
for (1..10) { 
    push @image, GD::Image->new($width,$height,1); 
}

I should also point out that you could use a hash, if you wanted to refer to them by name.

Code

my %image; 
 
foreach my $name ( qw(foo bar bazz) ) { 
    $image{$name} = GD::Image->($width,$height,1); 
}
