man File::Type::WebImages (3): 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.
