VERSION

       This document describes Test::CGI::Multipart::Gen::Image version 0.0.3

SYNOPSIS

           use Test::CGI::Multipart;
           use Test::CGI::Multipart::Gen::Image;

           my $tcm = Test::CGI::Multipart;

           # specify the form parameters
           $tcm->upload_file(
               name='Image',
               file=>'cleopatra.doc',
               width=>400,
               height=>250,
               instructions=>[
                   ['bgcolor,'red'],
                   ['fgcolor','blue'],
                   ['rectangle',30,30,100,100],
                   ['moveTo',280,210],
                   ['font','Times:italic'],
                   ['fontsize',20],
                   ['angle',-90],
                   ['string','Helloooooooooooo world!'],
               ],
               type=>'image/jpeg'
           );
           $tcm->set_param(name=>'first_name',value=>'Jim');
           $tcm->set_param(name=>'last_name',value=>'Hacker');

           # Behind the scenes this will fake the browser and web server behaviour
           # with regard to environment variables, MIME format and standard input.
           my $cgi = $tcm->create_cgi;

           # Okay now we have a CGI object which we can pass into the code
           # that needs testing and run the form handling various tests.

DESCRIPTION

       This is a callback package for Test::CGI::Multipart that facilitates the testing of the
       upload of text files of a given size and sample content.  One can specify the dimensions
       of the image and the size, font and colours of a simple string.

INTERFACE

       For information on how to use this module, see Test::CGI::Multipart especially the section
       on callbacks. What this module offers is that if the "type" parameter begins with 'image/'
       and there is no "value" parameter you can specify various human comprehensible inputs into
       the image rather than the raw binary.  In particular this covers what appears to be common
       use cases in testing image upload: namely images of various types, file sizes and
       dimensions.

       "type"
           The MIME type of the content. For this module to be interested this parameter must be
           set, and must begin with 'image/'.  What follows is taken to be the image format and
           is treated as a function to the GD::Image module.

       "width", "height"
           These are the requested dimensions of the proposed image. They are mandatory
           parameters.

       "font", "fontsize", "bgcolor", "fgcolor", "string"
           These parameters are passed straight through to the GD::Simple module.

DIAGNOSTICS

       "unexpected data structure"
           During the construction of the MIME data, the internal data structure turned out to
           have unexpected features.  Since we control that data structure that should not
           happen.

       "mismatch: is %s a file upload or not"
           The parameter was being used for both for file upload and normal parameters.

CONFIGURATION AND ENVIRONMENT

       Test::CGI::Multipart::Gen::Image requires no configuration files or environment variables.
