=head1 DESCRIPTION
|
|
|
|
This Perl extension allows the reading, manipulation and writing of
|
|
a large number of image file formats using the ImageMagick library.
|
|
It was originally developed to be used by CGI scripts for Web pages.
|
|
|
|
A web page has been set up for this extension. See:
|
|

https://imagemagick.org/script/perl-magick.php
