+     * 11x17, cd_front, inlay, inlay_nosides

+     * 'align' Alignment of the graph on the page, available options are:
+     * topleft, topcenter, topright, leftcenter, center, rightcenter,
+     * leftbottom, centerbottom, rightbottom
+     *
+     * 'orientation' Specifies the paper orientation, default is 'portrait' and
+     * 'landscape' is also supported.
+     *
+     * 'creator' The creator tag of the PDF/graph
+     *
+     * 'author' The author tag of the PDF/graph
+     *
+     * 'title' The title tag of the PDF/graph

+     * 'width' The width of the graph on the page

+     * 'height' The height of the graph on the page

+     * 'left' The left offset of the graph on the page
+     *
+     * 'top' The top offset of the graph on the page
+     *
+     * 'filename' The PDF file to open/add page to, using 'filename' requires
+     * the commercial version of PDFlib (http://www.pdflib.com/), this has for
+     * obvious ($ 450) reasons not been tested
+     *
+     * 'pdf' An existing PDFlib PDF document to add the page to
+     *
+     * 'add_page' (true/false) Used together with 'pdf', to specify whether the

+     * The 'page' and 'width' & 'height' can be mutually omitted, if 'page' is
+     * omitted the page is created using dimensions of width x height, and if
