 /**
  * Create the PDF canvas.
  *
  * Parameters available:
  *
  * 'page' Specify the page/paper format for the graph's page, available
  * formats are: A0, A1, A2, A3, A4, A5, A6, B5, letter, legal, ledger,
  * 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
  * canvas should add a new graph page (true) or create the graph on the
  * current page (false), default is 'true'
  *
  * 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
  * width and height are omitted the page dimensions are used for the graph.
  *
  * If 'pdf' is specified, 'filename', 'creator', 'author' and 'title' has no
  * effect.
  *
  * 'left' and 'top' are overridden by 'align'
  *
  * It is required either to specify 'width' & 'height' or 'page'.
  *
  * The PDF format/PDFlib has some limitations on the capabilities, which
  * means some functionality available using other canvass (fx. alpha
  * blending and gradient fills) are not supported with PDF (see Canvas.txt
  * in the docs/ folder for further details)
  *
  * @param array $param Parameter array
