=head1 SYNOPSIS

	package foo;
	use Meta::Image::Magick qw();
	my($image)=Meta::Image::Magick->new();
	my($thumbnail)=$object->thunb(50,50);

=head1 DESCRIPTION

Since I found there were a few methods I wanted that were missing from
Image::Magick I inherited from it and extended it. This is the result.
The original motivation was the creation of well scaled thumbnails.

=head1 FUNCTIONS

	Thumb($$$)
	TEST($)

=head1 FUNCTION DOCUMENTATION

=over 4

=item B<Thumb($$$)>

This method will create a thumbnail with x and y as the maximum x and
y size. It will make the image the largest possible within that frame
without distorting it. The image that will be returned may be smaller
than x and y dimensions but only in a single dimension.

=item B<TEST($)>

Test suite for this module.
