问题 Is there any way to shift / move the text inside existing pdf page to some other position ? Like there is some text at area x=100, y=100, w=100, h=100 and i want to move it to x=50, y=200, w=100, h=100. I did a lot of research and it seems iTextSharp cannot do that. PDFSharp claims that it can be done but i could not find any examples. One way is to make a bitmap of specific area of the text i want to shift, draw white rectangle over that area and insert bitmap at new location. I don't want

问题 We have an ASP.NET application that users use to generate certain reports. So far we had one PDF template that had one image on it, and we would just replace that image with our programatically generated one (graph). We have used code from this site for that:http://blog.rubypdf.com/2007/12/12/how-to-replace-images-in-a-pdf/ Problem now is that we have two different images on one PDF page, and the code from link above selects both images on one page and replaces them all at once with our

问题 I have a view that returns a pdf (using iTextSharp) with multiple pages, but now I have to change it so that each page is a separate pdf (with it's own unique title) and return a zip file. My original code looks like this: public FileStreamResult DownloadPDF() { MemoryStream workStream = new MemoryStream(); Document document = new Document(); PdfWriter.GetInstance(document, workStream).CloseStream = false; document.Open(); // Populate pdf items document.Close(); byte[] byteInfo = workStream

问题 I have a requirement to generate invoice reports in PDF using some predefined company templates. I am able to create/generate SINGLE PAGE PDF reports using iTextSharp. Problem: The problem comes when the invoice statement spans MULTIPLE PAGES . I am not able to extend the report(invoice statement) to next(2nd) page. If all the data can not be accommodated on one page it should be written on 2nd page, while still using the company template. The template is present at following path:

问题 I've looked up some documentations and examples under the http://developers.itextpdf.com/examples. I know iText is able to generate tagged pdf from scratch, but is it possible to insert alternative text to images in an existing tagged pdf (without changing anything else)? I need to implement this feature in a program without using GUI applications (such as Adobe Acrobat Pro). Thanks. 回答1: Please take a look at the AddAltTags example. In this example, we take a PDF with images of a fox and a

问题 I have a pdf , and I want to get the width and Height for each page in pdf using iTextSharp? given this is the pdf I want to work with string source=@"D:\pdf\test.pdf"; PdfReader reader = new PdfReader(source); 回答1: Do you want the MediaBox?

问题 I want to put a check mark using zapfdingbatslist on my pdf document in iTextSharp in a specific location . What I could do so far is I could show the check mark but it's all on the side of the document and not on a specific X, Y coordinate that I want it to be. I have a code below that would hopefully give you the idea of what I am talking about. String outputFile = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "Test.pdf"); System.IO.FileStream fs; Document doc =

问题 I'm using the latest version of iTextSharp found here: http://sourceforge.net/projects/itextsharp/ I am trying to use ColumnText.SetSimpleColumn after getting the position of some AcroFields using GetFieldPositions( fieldName ). All the examples I can find show GetFieldPositions returning a float[] however this doesn't appear to be the case anymore. It now appears to be returning IList which doesn't (according to Visual Studio) implicitly convert to a float[]. Inside the return value at the 0

问题 I want to extract an Image from a PDF file. I tried with the following code and it extracted a jpeg Image perfectly from the PDF. The problem is how to extract image from a particular page e.g. Page 1 or from some other page. I don't want to read the whole PDF to search for the Image. Any suggestions?
