问题 I am reading and filling a dynamic pdf template(having dynamic table with textfields in each cell) below way using iTextSharp [assuming I would be getting a single product info from source]: FileStream fs = new FileStream("C:\\ABC\\DestinationFile.pdf", FileMode.Create); PdfReader reader = new PdfReader("C:\\ABC\\SourceTemplateFile.pdf"); PdfStamper stamper = new PdfStamper(reader, fs); xfa = stamper.AcroFields.Xfa; string[] strProductList = productInfo.Product.Split('|'); string dName=

问题 I am trying to create a PDF on z/OS using JZOS and iText. I have tried so many combinations for the font as well as the DefaultPlatformEncoding but I just don't seem to be able to get the Arabic characters to display in the PDF. They display as Latin characters. When I turn the PDF compression off and display the hex characters, I see the EBCDIC hex codes. The input file on z/OS is IBM-420 and the output PDF should have Cp1256 or Windows-1256 for display on Windows. Here is the snippet of the

问题 I have an incoming jpg file, that I can set a colour to transparent. When I add the image to another image, this works perfectly. I am trying to add the same image to a PDF using iTextSharp, but I cannot get the transparency to work. I have tried two ways, but neither is working. The first way was to open the image in a Bitmap, set transparency, then use that Bitmap object in the PDF. The second way (shown here) was saving the Bitmap to disk and opening the file into the iTextSharp image.

问题 I've recently had to upgrade to iText, but I'm having problems getting setEncryption to work. I'm using iText 5.5.6. document = new Document(PageSize.LETTER, 36, 36, 72, 72); writer = PdfWriter.getInstance(document, out); writer.setEncryption(null, OWNER_PASSWORD.getBytes(), writer.AllowPrinting|writer.AllowCopy, PdfWriter.STANDARD_ENCRYPTION_128); gets me the following error: java.lang.SecurityException: class "org.bouncycastle.asn1.ASN1Primitive"'s signer information does not match signer

问题 This question compress pdf with large images via java gives the code to compress a PDF with iText in Java. Since in Android there are no Graphics2D, AffineTransform, BufferedImage and ImageIO, I thought of adapting this code by using the Bitmap class. UPDATE: Thanks to @TilmanHausherr, I modified the compression to JPEG and got the following working code. public static void manipulatePdf(String src, String dest) throws IOException, DocumentException { // Read the file PdfReader reader = new

问题 I want to add text into a rectangle(x,y,w,h). Text should be fitted size of rectangle (mean it has a maximum size but it still contains in rectangle). I tried to measure the text size base on BaseFont.getWidthPoint() The problem is the final text size can't fit the rect. It looks like this: Here is my try: PdfContentByte cb = writer.getDirectContent(); cb.saveState(); ColumnText ct = new ColumnText(writer.getDirectContent()); Font font = new Font(BaseFont.createFont()); int rectWidth = 80;

问题 Just as the title says, I'm using iTextSharp to generate a report. And I want to add a space between two tables, but I don't know how. this is my code: var boldFont = FontFactory.GetFont(FontFactory.HELVETICA_BOLD, 12); PdfPTable table1 = new PdfPTable(2); table1.WidthPercentage = 25; table1.HorizontalAlignment = Element.ALIGN_LEFT; table1.AddCell(new PdfPCell(new Paragraph("Factura No: "))); table1.AddCell(new PdfPCell(new Paragraph("#1"))); table1.AddCell(new PdfPCell(new Paragraph("Tipo

问题 I have the need to convert any multipage PDF file into a set of JPGs. Since the PDF files are supposed to come from a scanner, we can assume each page just contains a graphic object to extract, but I cannot be 100% sure of that. So, I need to convert any renderable content from each page into a single JPEG file. How can I do this with iText? If I can't do this with iText, what Java library can achieve this? Thanks. 回答1: ICEpdf - http://www.icepdf.org/ - has an open source entry version which
