问题 I'm creating a PDF file dynamically in an ASP.Net application. The data can vary from spanning 1 page to over 10 pages. I'm using PdpfTables and Cells to align the data which is working perfectly. IT's creating pages as it needs new pages. The only problem is I can't get it to add my template to all pages, only the first page. My Template is a 1 page PDF file.

问题 I don't know if it is possible to create a pdf with password security enabled, that also allows extraction of pages. I havn't found any property in itextsharp which will allow enable page extraction. Any one has any idea? This is the property that i would like to enable. Thank you very much. 回答1: I've taken a look at the permission bits in the draft of ISO-32000-2 and I've compared them with the parameters (written in ALL_CAPS) available in iText: bit 1: Not assigned bit 2: Not assigned bit 3

问题 I am creating PDF work orders that have a varying amount of items and notes. I am using ColumnText.SetSimpleColumn(phrase, x, y, x2, y2, height, alignment) to add text to a single column.
