Converts a page range of a PDF document to images using one of the defined image handlers:

image-to-image image-to-byte-array image-to-file

Or pass in a custom one. Returns a sequence consisting of the images, byte arrays or pathnames depending on the selected image handler.

Options are key-value pairs and may be one of: :page - Page to convert to image, takes precedence over :start-page and :end-page :start-page - The start page, defaults to 0 :end-page - The end page, defaults to PDF's pages length - 1 or Integer/MAX_VALUE :dpi - Screen resolution, defaults to 300 :quality - Quality to be used when compressing the image (0 < quality < 1), defaults to 1 :ext - The target file format, defaults to png :pdf-file - A PDF java.io.File, takes precedence over :pathname :pathname - Path to the PDF file, used if :pdf-file is not specified (= nil)
