itextsharp

问题 I have a table which I'm trying to space down about 20/30 floating points (f) from the top margin of a pdf document. The reason I want to space down a bit is because I have a rectangle border running around the margin of my pdf document. PdfPTable table = new PdfPTable(1); table.SpacingBefore = 20f; table.SpacingAfter = 20f; table.TotalWidth = 700f; table.LockedWidth = true; table.SpacingAfter works perfectly well but table.SpacingBefore will not, my table just sits at the top margin and will

问题 I use the last version of itextsharp. I use the property HeaderRows=1 so that if there is a pagebreak, the Header rows will appear again in the next page. Then we have the rows of the content with the border style without bottomline like this: PdfPCell cell1 = null; cell1 = new PdfPCell(new Phrase(string.Format("{0}", c1), fn)); cell1.Border = Rectangle.RIGHT_BORDER | Rectangle.LEFT_BORDER; When there is a pagebreak, the line bottom of the table is not shown, which is not logical. Even if the

问题 Is there a way we can delete the first page of the PDF using iTextSharp? 回答1: There's no direct way to remove pages from a PDF using iTextSharp. However, you can copy all the pages you want from a PDF and skip the pages you don't want. In your case you'd copy out all but the first page. I wrote a method that does this based on the code I found on this blog entry. 回答2: PdfReader reader_SecondPdf = new PdfReader(pdf_of_Second_File); for (j = 2; j <= reader_SecondPdf.NumberOfPages; j++) { } 回答3:

问题 I looked at a few examples online and came up with this code to merge pdfs using iTextSharp. But I am getting an error :. {"The document has no pages."} It fails at Page = writer.GetImportedPage(reader, X); Here is stack trace : at iTextSharp.text.pdf.PdfPages.WritePageTree() at iTextSharp.text.pdf.PdfWriter.Close() at iTextSharp.text.pdf.PdfCopy.Close() at iTextSharp.text.Document.Close() It has 3 pages when I debugged it.

问题 I am able to create barcode using itextsharp CreateDrawingImage method. But I want to include the actual text into the image. How do I do that? or How do I use CreateImageWithBarcode method to save as image (Jpeg/Png)? Thanks 回答1: Facing the same problem and after looking in iTextSharp sources it appears you can't. Besides with CreateDrawingImage() I had problems with image resizing, it was fuzzy and unreadable. I ended up using this library (very cool): http://www.codeproject.com/KB/graphics

问题 I am trying to read PDF file using iTextSharp. The issue is when trying to read a PDF file other than English (Hindi or Arabic for example) it's not getting the correct words. I am wondering, should I install the Hindi or Arabic font on my system or do I need to do something with encoding? ITextExtractionStrategy strategy = new SimpleTextExtractionStrategy(); string currentText = PdfTextExtractor.GetTextFromPage(pdfReader, page, strategy); currentText = Encoding.UTF8.GetString(ASCIIEncoding

问题 So we have some really inefficient code that splits a pdf into smaller chunks based on a maximum size allowed. Aka. if the max size is 10megs, an 8 meg file would be skipped, while a 16 meg file would be split based on the number of pages. This is code that I inherited and feel like there has got to be a more efficient way to do this that requiring only one method and less instantiation of objects. We use the following code to call the methods: List<int> splitPoints = null; List<byte[]>

问题 Is it possible to add a border to a page in a PDF document using iTextSharp ? I'm generating the PDF file from scratch, so I don't need to add borders to an already existing document. Here's my code for example: Document pdfDocument = new Document(PageSize.LETTER); Font headerFont = new Font(baseFont, 13); Font font = new Font(baseFont, 10); PdfWriter writer = PdfWriter.GetInstance(pdfDocument, new FileStream(fileName, FileMode.Create)); pdfDocument.Open(); //I add IElements here. pdfDocument
