CONSTRUCTOR

new

Create a WWW::LibraryThing::Covers object with the following parameters:

api_key

Your LibraryThing API key (required).

directory

Output directory for the cover images.

size

Default size for cover images (optional, defaults to medium). Possible values are large, medium and small.

not_found

Defines behaviour for cover images not available. LibraryThing returns a transparent 1�1 pixel GIF image.

delay

Delay between requests. Defaults to 1 second as this is required for automatic downloads.

user_agent

LWP::UserAgent object (optional).

METHODS

get

Retrieves an image for given isbn and size (optional).

The image is stored as ISBN.jpg in the directory provided to the constructor or just returned as scalar reference otherwise.

The actual return value in case of success is a list with three members:

  • Filename or scalar reference of the image data.

  • Image width.

  • Image size.

Returns undef in case of errors.

Returns 0 if constructor parameter not_found is set to return_zero and cover image is not available.
