NAME ^

File::Type::WebImages - determine web image file types using magic

SYNOPSIS ^

    use File::Type::WebImages 'mime_type';
    
    my $type_1 = mime_type($file);
    my $type_2 = mime_type($data);

DESCRIPTION ^

mime_type() can use either a filename, or file contents, to determine the type of a file. The process involves looking the data at the beginning of the file, sometimes called "magic numbers".

THE BIG TRADE OFF ^

For minimum memory consumption, only the following common web image file types are supported:

BMP, GIF, JPEG and PNG. ( image/bmp, image/gif, image/jpeg and image/png ).

Unlike with File::Type and File::MMagic, 'undef', not "application/octet-stream" will be returned for unknown formats.

Unlike File::Type, we return "image/png" for PNGs, not "image/x-png";

If you want more mime types detected use File::Type or some other module.

TODO ^

It would be even better to have a pluggable system that would allow you to plug-in different sets of MIME-types you care about.

SEE ALSO ^

File::Type. Similar, but supports over 100 file types.

ACKNOWLEDGMENTS ^

File::Type::WebImages is built from a mime-magic file from cleancode.org. The original can be found at http://cleancode.org/cgi-bin/viewcvs.cgi/email/mime-magic.mime?rev=1.1.1.1.
