SYNOPSIS # Use via imgsize CLI script FUNCTIONS imgsize Usage: imgsize(%args) -> [status, msg, payload, meta] Show dimensions of image files. Examples: * Example #1: imgsize(filenames => ["foo.jpg"]); # -> [200, "OK", "640x480", {}] * Example #2: imgsize(filenames => ["foo.jpg"], detail => 1); Result: [ 200, "OK", [ { filename => "foo.jpg", filesize => 23844, width => 640, height => 480, res_name => "VGA", }, ], { "table.fields" => ["filename", "filesize", "width", "height", "res_name"], }, ] * Example #3: imgsize(filenames => ["foo.jpg", "bar.png", "baz.txt"]); Result: [ 200, "OK", [ { filename => "foo.jpg", filesize => 23844, width => 640, height => 480, res_name => "VGA", }, { filename => "bar.png", filesize => 87374, width => 400, height => 200, res_name => undef, }, { filename => "baz.txt", filesize => 2393, width => 0, height => 0, res_name => undef, }, ], { "table.fields" => ["filename", "filesize", "width", "height", "res_name"], }, ] 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]* Returns an enveloped result (an array). First element (status) is an integer containing HTTP status code (200 means OK, 4xx caller error, 5xx function error). Second element (msg) is a string containing error message, or 'OK' if status is 200. Third element (payload) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information. Return value: (any) HOMEPAGE Please visit the project's homepage at .
