How to define the page size based on the content?

I'm generating a PDF document with iTextSharp. This document must have only one page. In other words the content must fit the page size. Is it possible to achieve this with iTextSharp?

I tried to get the height of the content before adding it to the document, so I can calculate the total size before creating the document, but some content types (tables for example) don't have height until they are added to the document.

If you create a PdfPTable and if you define the width of the table, for instance like this:

table.TotalWidth = 400f;
table.LockedWidth = true;

Then you can use ask the table for its height like this:

Float h = table.TotalHeight;

You can use h to define your page size, for instance:

Document document = new Document(400, h, 0, 0, 0, 0);

Note that all measurements are done in user units and that one user unit equals 1 pt by default. The getTotalHeight() method will return 0 if you don't define the width, because the height depends on the width and the table doesn't know the width before it is rendered.
