MigraDoc - only Last Page Footer

问题

I have this code:

        Document document = new Document();

        Section sec = document.AddSection();
        Paragraph par;

        for (int i = 0; i < 50; i++)
        {
            par = sec.AddParagraph();
            par.AddText("Wiki je označení webů (nebo obecněji hypertextových dokumentů), které umožňují uživatelům přidávat obsah podobně jako v internetových diskusích, ale navíc jim také umožňují měnit stávající obsah; v přeneseném smyslu se jako wiki označuje software, který takovéto weby vytváří.Původně se termín wiki používal zcela opačně. Wiki bylo označení typu softwaru a weby postavené.");
        }

        par = sec.Headers.Primary.AddParagraph();
        par.AddText("hlavicka");
        Borders hranice = new Borders();
        hranice.Width = 1;
        sec.Headers.Primary.Format.Borders = hranice;

        sec.AddImage("images.jpg");

        par = sec.AddParagraph();
        par.AddText("paticka");

        PdfDocumentRenderer print = new PdfDocumentRenderer(false, PdfFontEmbedding.Always);
        print.Document = document;
        print.RenderDocument();
        print.PdfDocument.Save("ahoj.pdf");

I need to make a Footer only on the last page. Is it possible?

回答1:

There is no way to create a real footer on the last page.

You can create a TextFrame with your last paragraph. TextFrames are Shapes and can be placed at an absolute position on the page, so you can also place them where the Footer would be.

回答2:

For example:
You need a 30mm place over the footer on the last page. (That could be a signature field.)

Define the PageSetup without this place (only footer hight + your distance from the bottom of the page)
Define your 30mm paragraph or table as TextFrame on a fix position: TextFrame.RelativeVertical = RelativeVertical.Page; frame.Top = ShapePosition.Bottom;
Define an empty paragraph as the last paragraph of the document with paragraph.Format.SpaceBefore = 30mm

Now the 30mm empty paragraph is on the end of all Documents and the signature overlapped it or the place for signature is not enough. Then the 30mm empty place forces a page break.
