times = new (bfTimes, 12,, BaseColor.DARK_GRAY) ĭocument doc = new Document(. Add the following dependencies to your pom.xml and Maven will manage these dependencies automatically. Maven Dependencies We use Apache Maven to manage our project dependencies. Step 2 Create an iTextSample project as shown below. In this tutorial we show how to encrypt decrypt password protected PDF documents using iText. Step 1 Install Eclipse and open a new project in it as shown below. Private void button2_Click(object sender, EventArgs e)īaseFont bfTimes = BaseFont.CreateFont(BaseFont.TIMES_ROMAN, BaseFont.CP1252, false) Follow the steps given below to set the iText environment on Eclipse. Using (MemoryStream msDoc = new MemoryStream()) ", directoryInfo.FullName) * manipulate image files in ASP.NET applications, see the warning here: The main use is when concatenating multiple documents to keep the memory usage restricted to the current appending document. * you DO NOT want to use classes within the System.Drawing namespace to Description copied from class: PdfWriter Use this method to writes the reader to the document and free the memory used by it. We can also pass a stream instead - removing the need for the first MemoryStream using block.//. PdfDocument to take in the reader and produce results in the writer.įeel free to swap out the using blocks for.PdfWriter to write to the output stream.Another MemoryStream to serve as the PDF stream after the pages have been deleted.MemoryStream for reading in the byte array.In the order of above, the resources being managed are: Using (var document = new PdfDocument(reader, writer))Īs many iText7 Pdf objects implement IDisposable we have to manually release the unmanaged resources. Using (var writer = new PdfWriter(outputStream)) You can vote up the ones you like or vote down the ones you don't like, and go to the original project or source file by following the links above each example. These examples are extracted from open source projects. Using (var outputStream = new MemoryStream()) The following examples show how to use .PdfWritergetInstance(). Using (var reader = new PdfReader(inputStream)) Using (var inputStream = new MemoryStream(pdf)) Then with iText7, call the following: public byte DeletePages(byte pdf, IEnumerable pageNumbers) : Represents the generic document in which elements like paragraph, list tables etc are added and then finally this document is written to the PDF file. The PDF in result has no images at all But the result its without image because itext7 support base64 image. iText API Description Find the description of commonly used iText API. You could change the following setting to verify: Debug -> Exceptions -> Remove the checkbox in the column 'Thrown' of 'Common Language Runtime Exceptions'. This list is a normal 1 based index, meaning page 1 of the document is a 1 in the list.įor example, to delete pages 2, 5 and 6 you could pass in: new List Hello there, I am use Open XML SDK to convert docx word to html file and use iText (Version 7.1.1) to convert html to pdf using HtmlConverter (html2pdf version 2.0.1). If you don't catch any exceptions,this NullReferenceException can very well be one that is already caught and handled inside iTextSharp, so you don't care about it. This takes in a byte array and any sort of IEnumerable of type int ( List/ Array/etc) to represent which page numbers to delete. The full code for that line is: C: Paragraph header new Paragraph('HEADER').SetTextAlignment(TextAlignment.CENTER).SetFontSize(20) By the fluent interfaces convention, SetFont () should return the this reference, but bugs and typos do happen. I have a PDF document (using iText 7/C 4.01) that I am creating in a MemoryStream and at the end, I want to write it out to a file.
