问题 I am currently generating a large document from a database scheme and especially in bigger databases the amount of pages quickly exceeds 1000 pages... I use PDFBox to create the document and I am wondering whether PDFBox supports any way of creating Bookmarks that are displayed in the left side of Acrobat when viewing the document.

问题 I'm trying to include an image into a pdf wich is generated via XSL using Apache Cocoon. I've read about the tag <fo:external-graphic> wich works fine when a image is stored on the local drive or when you request an image wich resides physically on any server. But what i need is to show in the pdf an image (codebar image) wich is generated dinamically by a jsp , that is to say, java generates the image and it will never be stored on the hard drive. The image is generated correctly by the jsp

So I need some kind of margin for the HTML only. Here is my code so far: var doc = new Doc(); doc.MediaBox.String = "A4"; doc.Rect.String = doc.MediaBox.String; var id = doc.AddImageUrl(url.ToString()); doc.AddImageDoc("template.pdf", 1, doc.MediaBox); while (doc.Chainable(id)) { doc.Page = doc.AddPage(); id = doc.AddImageToChain(id);

问题 I am generating collections (Acrobat Portfolios) via iTextSharp. I would like to assign an existing custom navigator (custom layout) to the generated collection. I believe iTextSharp allows for the CUSTOM parameter to define a custom navigator, as in the last code line of this block: Document document = new Document(); FileStream stream = new FileStream(portfolioPath, FileMode.Create); PdfWriter writer = PdfWriter.GetInstance(document, stream); document.Open(); document.Add(new Paragraph(" ")
