A while back I engaged in an experiment combining two of my interests - Perl and quilting. I was pleased with the outcome, and decided to continue working on my script to extend its capabilities. This version uses Image::Magick to create an image of the generated random layout.

#!/usr/bin/perl -w
use strict;
use Image::Magick;

# Revenge of the Perl Quilt
#  - an extension of the original perl quilt generator that
# uses ImageMagick to create a montage image of the generated layout

my @swatch;
my @quilt;
my $number_of_blocks;
my $number_of_columns;
my $number_of_rows;
my %numbers_to_fabrics; # This is a hash containing the 
# number and the location of the fabric images. For example,
# my %numbers_to_fabrics = (1 => 'red.jpg', 2 => 
# 'yellow.jpg', 3 => 'blue.jpg')
my $count = scalar keys %numbers_to_fabrics;

# Prompt for the number of columns and rows desired.
do {
   print "How many columns would you like? \n";
      chomp($number_of_columns = <STDIN>);
   print "How many rows would you like? \n";
      chomp($number_of_rows = <STDIN>);
   $number_of_blocks = $number_of_columns * $number_of_rows
   } 
# Check that the number of blocks is less than or equal 
# to the number of available fabrics. At this time, to 
# reuse a fabric requires that it be entered multiple times 
# in the hash. I'll probably revise this later.
   until ($number_of_blocks <= $count);

@swatch=(1 .. $number_of_blocks);
my $images = Image::Magick->new();
while (@swatch) {
   my $x = rand(@swatch);
   my $v = $swatch[$x];
   # This print statement is useful for finding
