=head1 NAME

Image::Magick - Perl extension for calling ImageMagick's libMagick methods

=head1 SYNOPSIS

  use Image::Magick;
  $p = new Image::Magick;
  $p->Read("imagefile");
  $p->Set(attribute => value, ...)
  ($a, ...) = $p->Get("attribute", ...)
  $p->routine(parameter => value, ...)
  $p->Mogrify("Routine", parameter => value, ...)
  $p->Write("filename");

=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:

	 file://@DOCUMENTATION_PATH@/www/perl-magick.html
