阅读更多关于 iTextSharp for PDF - how add file attachments?

问题 I am using iTextSharp to create a PDF document in C#. I would like to attach another file to the PDF. I'm having just loads of trouble trying to do so. The examples here show some annotations, which apparently attachments are. This is what I've tried: writer.AddAnnotation(its.pdf.PdfAnnotation.CreateFileAttachment(writer, new iTextSharp.text.Rectangle(100,100,100,100), "File Attachment", its.pdf.PdfFileSpecification.FileExtern(writer, "C:\\test.xml"))); Well, what happens is it does add an

阅读更多关于 Header, footer and large tables with iTextSharp

问题 I've added an header and a footer on my document by PdfPageEventHelper. The document has several "large" tables populated at runtime.

阅读更多关于 Rotating PDF 90 degrees using iTextSharp in C#

问题 I am trying to use a PDF for stamping and need to rotate it 90 degrees to lay it on correctly? Anyone know how to do this? Can't seem to find it online. 回答1: The Rotate90Degrees example uses PdfReader to get an instance of the document then changes the /Rotate value in every page dictionary. If there is no such entry, a /Rotate entry with value 90 is added: final PdfReader reader = new PdfReader(source); final int pagesCount = reader.getNumberOfPages(); for (int n = 1; n <= pagesCount; n++) {

What are the ways of checking if piece of text in PDF documernt is bold using iTextSharp

阅读更多关于 What are the ways of checking if piece of text in PDF documernt is bold using iTextSharp

I have an application, that extracts headings out of pdf files. The documents, that the application is supposed to work with, all have more or less coherent structure and formatting, in fact, telling if a text chunk is bold or not, is very important. Recently I came across a bunch of files, where some chunks visually appear bold, but do not have "bold" piece in string representation of font. The following SO thread how can i get text formatting with iTextSharp helped me to understand, that there is one more way of making text appear bold. However in my case calling GetTextRenderMode() does not

Get ONLY word count from PDF document

阅读更多关于 Get ONLY word count from PDF document

问题 I was hoping to get just the word count from a pdf document programmatically. I've looked at PDFSharp, but it's awefully bulky for what I want to do. I don't have access to the server, so I can't install acrobat to get to their api's or anything. I'd be willing to do it in iTextSharp or another tool. 回答1: iTextSharp has a wonderful PdfTextExtractor object that will get you all of the text (assumming as @Rob A pointed out that its actually stored as text and not images or pure vector). Once

How to Set Height of PdfPTable in iTextSharp

阅读更多关于 How to Set Height of PdfPTable in iTextSharp

i downloaded the last version of iTextSharp dll. I generated a PdfPTable object and i have to set it's height. Despite to set width of PdfPTable, im not able to set height of it. Some authors suggest to use 'setFixedHeight' method. But the last version of iTextSharp.dll has not method as 'setFixedHeight'. It's version is 5.5.2. How can i do it?

For instance, if you set a two row table to a height of 500, does that mean that each cell get's 250
