However, a commercial license is needed for usage in any commercial project.

That means the library is free to use in open source projects. The library has been using the AGPL license model since iText 5. In addition to this, they can benefit from our rich and up-to-date technical documentation in the Resource Center.

At the same time your development team has full access to all internal PDF structures, offering them the possibility to read, insert, update and delete any PDF object they want. With iText 7 Core you don't have to worry about PDF technologies and standards, you can just focus on your business needs and document content. IText 7 Core is a straightforward, performant and extensible library that is ready to handle the challenges of today's digital document workflows. See some definitions from the iText site. The library is a collection of several components, but the primary concern of this article is the IText Core component. It can be used to create static or dynamic PDFs and manipulate already existing PDFs with minimum concern for the PDF standards. The iText library can be used to manipulate almost any PDF. To start, I'll begin with a short overview of the library to provide readers with a better understanding of the concept. This will be followed by examples of styling texts or paragraphs.

I will provide an example of how to generate a PDF using the library and some methods for testing PDF content. If that assumption happens to be wrong, you might want to use PdfAnnotation.In this article, I will introduce the latest version of the iText 7 library. In the course of layout'ing your chunks, ColumnText also establishes the desired goto-emebedded links.īy the way, from your writing embedded files and using a PdfAction.GotoEmbedded I assumed you attach another PDF. (I used somewhat more descriptive names than your f.sDataFileName, s, b)
PdfAction action = PdfAction.GotoEmbedded(null, target, dest, true) PdfContentByte cb = stamper.GetOverContent(1) Ĭt.SetSimpleColumn(30, 30, reader.GetPageSize(1).GetRight(30), 60) PdfFileSpecification pfs = PdfFileSpecification.FileEmbedded(stamper.Writer, pdfPath, pdfName, pdfBytes) Using (PdfStamper stamper = new PdfStamper(reader, new FileStream(result, FileMode.Create, FileAccess.Write))) You can do this by means of a ColumnText instance like this: using (PdfReader reader = new PdfReader(source)) Thus, to allow for new content to be automatically layout'ed, you have to tell iTextSharp where to put the content. In particular in case of pages the stamper retrieved from the underlying PdfReader (and didn't add to them) this does make sense: If there is content somehow scattered across a page, where should the stamper add the new content? Should it consider the existing content background material and start at the top? Or should it somehow find a big unused page area and paint the elements there? (In case of newly added pages, though, the stamper indeed could have been programmed to serve like a regular PdfWriter and have allowed linkage with a Document to automatically layout content.)

Nonetheless, this assumption is wrong, the class hierarchies overlap for internal code reuse reasons, not to suggest similar usages the Add implementation of the PdfWriter descendant iText_Stamper.Writer merely returns false and does not even attempt to add the given element to the document. The class hierarchy unfortunately suggests this as both PdfWriter and Document implement the interface IElementListener which provides a method bool Add(IElement element). The main issue in your code is that you assume that the PdfWriter descendant iText_Stamper.Writer can be used like a Document to which you can add text chunks using the Add method, and expect iTextSharp to layout such material automatically. PdfDestination dest = new PdfDestination(PdfDestination.FIT) PdfTargetDictionary target = new PdfTargetDictionary(true) IText_Stamper.AddFileAttachment(desc, pfs) With: PdfFileSpecification pfs = PdfFileSpecification.FileEmbedded(iText_Stamper.Writer, I've replaced the : iText_Stamper.AddFileAttachment(desc, b, s, s) The thing is i want to add files to my pdf document as an embedded files,Ĭan some one tell me if i'm doing this the right way?!
I'm having a little bit trouble changing from PdfStamper.AddFileAttachment that receives four arguments to PdfStamper.AddFileAttachment which recieves PdfFileSpecification object as an argument.
