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'],

['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.
