NAME
    Image::Imlib2::Thumbnail::S3 - Generate thumbnails of an image into S3

SYNOPSIS
      use Image::Imlib2::Thumbnail;
      use Image::Imlib2::Thumbnail::S3;
      use Net::Amazon::S3;

      my $thumbnail = Image::Imlib2::Thumbnail->new;
      # add extra sizes if necessary
      $thumbnail->add_size(
          {   type   => 'landscape',
              name   => 'header',
              width  => 350,
              height => 200
          }
      );

      my $aws_access_key_id     = 'fill me in ';
      my $aws_secret_access_key = 'fill me in too';

      my $s3 = Net::Amazon::S3->new(
          {   aws_access_key_id     => $aws_access_key_id,
              aws_secret_access_key => $aws_secret_access_key,
          }
      );
  
      # create a bucket...
      my $bucket = $s3->add_bucket( { bucket => 'image_imlib2_thumbnail_s3' } )
          or die $s3->err . ": " . $s3->errstr;
      # ... or use an existing one:
      my $bucket = $s3->bucket('image_imlib2_thumbnail_s3');
  
      my $thumbnail_s3 = Image::Imlib2::Thumbnail::S3->new(
          {   thumbnail => $thumbnail,
              bucket    => $bucket,
          }
      );

      my @thumbnails = $thumbnail_s3->generate( 'photo.jpg', 'thumbnails/4' );
      foreach my $thumbnail (@thumbnails) {
          my $name   = $thumbnail->{name};
          my $width  = $thumbnail->{width};
          my $height = $thumbnail->{height};
          my $type   = $thumbnail->{type};
          my $key    = $thumbnail->{key};
          my $url    = $thumbnail->{url};
          print "$name/$type is $width x $height at $url ($key)\n";
      }

DESCRIPTION
    This module generates a set of thumbnails of an image and stores them in
    Amazon S3.

    Digital cameras take photos in many different sizes and aspect ratios.
    Photo websites need to display thumbnails of different sizes of these
    photos. This module makes it easy to generate a series of thumbnails of
    an image of the right sizes. It resizes and crops images to match the
    requires size and uploads them to Amazon's Simple Storage Service.

    What sizes does it generate? By default it generates thumbnails of the
    same dimension that Flickr generates. See Image::Imlib2::Thumbnail.

    It makes the thumbnails publically-readable and uploads the original
    photo but keeps that private.

METHODS
new
    The constructor. Takes an Image::Imlib2::Thumbnail object and a
    Net::Amazon::S3::Bucket object.

      my $thumbnail_s3 = Image::Imlib2::Thumbnail::S3->new(
          {   thumbnail => $thumbnail,
              bucket    => $bucket,
          }
      );

  generate
    Generates a set of thumbnails for the image and stores them in S3. It
    makes the thumbnails publically-readable and uploads the original photo
    but keeps that private. You pass in a filename and a key prefix. For
    example, with the code below the URLs will be:

      http://s3.amazonaws.com/image_imlib2_thumbnail_s3/thumbnails/4/original.jpg
      http://s3.amazonaws.com/image_imlib2_thumbnail_s3/thumbnails/4/square.jpg
      http://s3.amazonaws.com/image_imlib2_thumbnail_s3/thumbnails/4/thumbnail.jpg
      http://s3.amazonaws.com/image_imlib2_thumbnail_s3/thumbnails/4/small.jpg
      http://s3.amazonaws.com/image_imlib2_thumbnail_s3/thumbnails/4/medium.jpg
      http://s3.amazonaws.com/image_imlib2_thumbnail_s3/thumbnails/4/large.jpg
      http://s3.amazonaws.com/image_imlib2_thumbnail_s3/thumbnails/4/header.jpg

      my @thumbnails = $thumbnail_s3->generate( 'photo.jpg', 'thumbnails/4' );
      foreach my $thumbnail (@thumbnails) {
          my $name   = $thumbnail->{name};
          my $width  = $thumbnail->{width};
          my $height = $thumbnail->{height};
          my $type   = $thumbnail->{type};
          my $key    = $thumbnail->{key};
          my $url    = $thumbnail->{url};
          print "$name/$type is $width x $height at $url ($key)\n";
      }
