Header from files ?


Can I get size info of a file (GIF, JPG etc.) from its header ?

After I upload a file using the "file" input type, I require the width and height of the uploaded image in my Perl program.
How can I get it?

You want to use the Image::Size module. It knows 7 different file formats. Usage is simple:

use CGI ':all';
use Image::Size 'attr_imgsize';
print img({-SRC => '/server/images/arrow.gif',
  attr_imgsize('/server_root/server/images/arrow.gif')});


Get it from: http://www.cpan.org/authors/id/RJRAY/

Thanks.

But how do I find out if a particular module is already present in our server?
