SYNOPSIS

           use CGI::Application::Plugin::JSON qw(to_json);
           use CGI::Application::Plugin::AJAXUpload;

               my $profile = $c->ajax_upload_default_profile;
               $profile->{field_filters}->{value} = filter_resize(300,200);

               $c->ajax_upload_setup(
                   run_mode=>'file_upload',
                   upload_subdir=>'/img/uploads',
                   dfv_profile=>$profile,

               return;
           }

DESCRIPTION

       This module rewrites and formats an image. It is intended specifically to work with
       CGI::Application::Plugin::AJAXUpload and hence Data::FormValidator. Unlike, for example
       Data::FormValidator::Filters::Image, it takes raw image data and returns raw image data.

INTERFACE

   filter_resize
       This returns the subroutine reference that does the work. It takes as arguments the width
       and height in that order. There is an optional third argument which is the format. This
       defaults to "jpeg" but can be anything that works as a method on a GD::Image object
       returning image data.

ACKNOWLEDGEMENTS

       The core of the code is copied from Image::Resize. However the constructor for that module
       does not take raw data.

DEPENDENCIES

       This module uses the GD module.
