A new type of quote script

[mousey]

Want a new quote script? This will output a picture of a quote in a quote file with quotes on seperate lines. It will even auto-size itself to the quote.

#!/usr/bin/perl

use CGI::Carp;
use GD;

my $quote = &getquote;

my $img = GD::Image->new(length($quote)*8+30,46);

my $white = $img->colorAllocate(255,255,255);
my $black = $img->colorAllocate(0,0,0);

$img->transparent($white);

$img->string(gdLargeFont,15,15,$quote,$black);
print "Content-type: image/jpeg\n\n";
binmode(STDOUT);
print STDOUT $img->jpeg;

sub getquote {
  open FILE, 'quotes.txt' or die "Can't open quotes.txt: $!\n";
  my @quotes = <FILE>;
  close FILE;
  chomp(@quotes);
  my $quote = $quotes[rand @quotes];
  return $quote;
}

update: made the script much faster by having it output in jpeg format.

I wrote one too (once upon a time) whilst learning about GD, but I was just reading off *DATA

#!C:/perl/bin/perl
#!/usr/bin/perl

BEGIN {
    unless( -t STDIN){ # if run on commandline, none of this
        require CGI::Carp;
        CGI::Carp::carpout(\*LOGGY)
            if open(LOGGY,'>>'.__FILE__.'.err.log');
        CGI::Carp->import( 'fatalsToBrowser' );
    }
}
use strict;
use warnings;

use GD;
use constant PI => 3.141519; # close enough
use GD::Text::Wrap;
use GD::Text::Align;

my $quote = [ grep { $_ } map { chomp; $_ } <DATA> ];
$quote = $$quote[rand @$quote];

my $author = substr $quote,
             rindex($quote,'--'),
             length($quote) -rindex($quote, '--'),
             '';

#my $gd = GD::Image->new(800,600);
my $gd = GD::Image->new(800,600);

$gd->colorAllocate(255, 255, 255);

my $black = $gd->colorAllocate(0, 0, 0);
my $red = $gd->colorAllocate(255, 0, 0);
my $blue = $gd->colorAllocate(0, 0, 255);

#$gd->transparent($red);
$gd->interlaced('true');

$quote = GD::Text::Wrap->new(
      $gd,
      width       => 800, # has no effect (a bug)
      line_space  => 4,
      color       => $black,
      text        => $quote,
      preserve_nl => 1,
);

$quote->set_font(gdLargeFont);
$quote->set(align => 'center', width => 12 * 30);
$quote->draw(10,10);


$author = GD::Text::Align->new($gd,
        valign => 'base',
        halign => 'right',
        text   => $author,
    );

$author->set_font(gdLargeFont);

# STUPID API, always have to pass x,y, otherwise its undef
my($left, $top, $right, $bottom) = $quote->get_bounds(10,10);
$author->draw( $right , $bottom + 20, PI, $blue);
$gd->rectangle( $left -10, $top -10, $right +10, $bottom + 35 , $red);

# resize the image (even if it don't affect file-size much for png's)
my $gd2 = GD::Image->new( $right + 12, $bottom + 37 );

#$image->copy(sourceImage,dstX,dstY,srcX,srcY,width,height) object 
$gd2->copy( $gd, 0,0,0,0, $right + 12, $bottom + 37 );

print qq{Expires: Thu, 01 Jan 1970 00:00:00 GMT
Date: Fri, 02 Jan 1970 00:00:00 GMT
Content-Type: Image/Png\r\n\r\n};

binmode(STDOUT);
print $gd2->png();
