The 'inner structure' - the page descriptions - are presumed to be generated before each page is saved. pdfgen.py calls this and provides a 'canvas' object to handle page marking operators. piddlePDF calls pdfgen and offers a high-level interface. The classes within this generally mirror structures in the PDF file and are not part of any public interface. Instead, canvas and font classes are made available elsewhere for users to manipulate.

The 'page' argument, an integer, is the page number in the PDF document with which the 'label' should be associated. Page numbering in the PDF starts at zero! Thus, to change the label on the first page, '0' should be provided as an argument, and to change the 6th page, '5' should be provided as the argument. The 'label' argument should be a PDFPageLabel instance, which describes the format of the labels starting on page 'page' in the PDF and continuing until the next encounter of a PDFPageLabel. The order in which labels are added is not important.

PDF page labels have nothing to do with 'physical' page numbers printed on a canvas, but instead influence the 'logical' page numbers displayed by PDF viewers. However, when using roman numerals (i, ii, iii...) or page prefixes for appendecies (A.1, A.2...) on the physical pages PDF page labels are necessary to change the logical page numbers displayed by the PDF viewer to match up with the physical numbers. A PDFPageLabel changes the properties of numbering at the page on which it appears (see the class 'PDFPageLabels' for specifying where a PDFPageLabel is associated) and all subsequent pages, until a new PDFPageLabel is encountered. The arguments to this initialiser determine the properties of all subsequent page labels. 'style' determines the numberings style, arabic, roman, letters; 'start' specifies the starting number; and 'prefix' any prefix to be applied to the page numbers. All these arguments can be left out or set to None. * style: - None: No numbering, can be used to display the prefix only. - PDFPageLabel.ARABIC: Use arabic numbers: 1, 2, 3, 4... - PDFPageLabel.ROMAN_UPPER: Use upper case roman numerals: I, II, III... - PDFPageLabel.ROMAN_LOWER: Use lower case roman numerals: i, ii, iii... - PDFPageLabel.LETTERS_UPPER: Use upper case letters: A, B, C, D... - PDFPageLabel.LETTERS_LOWER: Use lower case letters: a, b, c, d... * start: - An integer specifying the starting number for this PDFPageLabel. This can be used when numbering style changes to reset the page number back to one, ie from roman to arabic, or from arabic to appendecies. Can be any positive integer or None. I'm not sure what the effect of specifying None is, probably that page numbering continues with the current sequence, I'd have to check the spec to clarify though. * prefix: - A string which is prefixed to the page numbers. Can be used to display appendecies in the format: A.1, A.2, ..., B.1, B.2, ... where a PDFPageLabel is used to set the properties for the first page of each appendix to restart the page numbering at one and set the prefix to the appropriate letter for current appendix. The prefix can also be used to display text only, if the 'style' is set to None. This can be used to display strings such as 'Front', 'Back', or 'Cover' for the covers on books.
