},
{
filename => "bar.png",

res_name => undef,
},
{
filename => "baz.txt",
filesize => 2393,

This function is not exported by default, but exportable.
Arguments ('*' denotes required arguments):
* detail => *bool*
Whether to show detailed records.
The default is to show detailed records when there are more than 1
filenames specified; when there is only 1 filename, will only show
dimension in WxH format (e.g. 640x480). If this option is specified,
will show detailed records even if there is only one filename
specified.
* filenames* => *array[filename]*
(No description)
Returns an enveloped result (an array).
First element ($status_code) is an integer containing HTTP-like status
code (200 means OK, 4xx caller error, 5xx function error). Second
element ($reason) is a string containing error message, or something
like "OK" if status is 200. Third element ($payload) is the actual
result, but usually not present when enveloped result is an error
response ($status_code is not 2xx). Fourth element (%result_meta) is
called result metadata and is optional, a hash that contains extra
information, much like how HTTP response headers provide additional
metadata.
Return value: (any)

CONTRIBUTING
To contribute, you can send patches by email/via RT, or send pull
requests on GitHub.
Most of the time, you don't need to build the distribution yourself. You
can simply modify the code, then test via:
% prove -l
If you want to build the distribution (e.g. to try to install it locally
on your system), you can install Dist::Zilla,
Dist::Zilla::PluginBundle::Author::PERLANCAR,
Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two
other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps
required beyond that are considered a bug and can be reported to me.
