Class Method Details

.call(path, image_extension:, image_file_basename_template:) ⇒ Enumerable, ...

Split the file found at the given :path

Parameters:

  • path (String) —

    the path to the source PDF that we’re processing.

  • image_extension (String) —

    used to determine the splitting service we use; there is an implicit relationship between image_extension and image_file_basename_template (though filenames do not necessarily reflect mime types)

  • image_file_basename_template (String) —

    use this string to generate the unique filename for an image “split” from the given PDF. It must include “%d” as part of the declaration. For example if the template is “hello-world-%d.png” then the first split page will be “hello-world-1.png”.
