itext7

问题 In iText7 I need to create 5 lines of text at the top of a document that are centered to the page. The easiest way I found to do this is: doc.add(new Paragraph("text of line 1").SetTextAlignment(TextAlignment.CENTER)); doc.add(new Paragraph("text of line 2").SetTextAlignment(TextAlignment.CENTER)); etc. However there is a larger amount of space between each of the lines than I want.

Converting a text to PDF and adding a TOC is an easy task when following iText example here, but apparently it is not possible when converting HTML to PDF.

问题 I'm trying to get this c# function from within a asp.netcore razor project using itext7 (7.1.7) to output a div containing text that scales up to within the constraints given with height and width.
