Third, the built-in class that's been around for years is the HTMLWorker however this has been replaced with XMLWorker ( Java /. If you get an exception saying The document has no pages or you think that "iText isn't parsing my HTML" it is almost definite that you don't actually have HTML, you only think you do. It is your responsibility to get the HTML from your choice of framework, iText won't help you. which are all framework-specific abstractions. Same with DataGridViews, Repeaters, Templates, Views, etc. ASP.Net, MVC, Razor, Struts, Spring, etc, are all HTML frameworks but iText/iTextSharp is 100% unaware of them. Second, iText and iTextSharp parse HTML and CSS. You also don't say "here's a table" but instead you say "draw this text at this exact location and then draw a rectangle at this other exact location that I've previously calculated so I know it will appear to be around the text".

Instead you say, "draw this text at this exact X,Y location using this exact font and don't worry, I've previously calculated the width of the text so I know it will all fit on this line". (There are other things like annotations and movies but I'm trying to keep it simple here.) In a PDF you don't say "here's a paragraph, browser do your thing!". There are three basic things that PDF supports: text, lines/shapes and images. A PDF file, however, must be independent of the rendering device, so regardless of your screen size it must always render exactly the same.īecause of the musts above, PDF doesn't support abstract things like "tables" or "paragraphs". In an HTML document you might have a paragraph that's 100% wide and depending on the width of your monitor it might take 2 lines or 10 lines and when you print it it might be 7 lines and when you look at it on your phone it might take 20 lines. PDF is intended to convey documents and the documents must "look" the same wherever they are rendered. Although there are methods to control it, it is ultimately up to the browser to draw these higher level concepts. HTML is intended to convey higher level information such as paragraphs and tables. First, HTML and PDF are not related although they were created around the same time.
