Sporadic Problem with getPageNumber

Dominic Maricic — 2008-12-03T22:16:12

Hi Guys, Sorry if this posts twice. I tried posting it using Google Chrome about 14 hours ago and it still hasn't appeared so I'm going to assume it's another bug in their program. I've been using iText for years (using the latest version right now) and have had one problem that's occasionally occured. I finally sat down and tried to figure the problem out and here's my issue: I generate a table of contents which is a combination of a few tables. I call document.getNewPage, then call write.getPageNumber() before I start writing the TOC and I call it right after. Then I subtract the two and add 1 (as the TOC could start and end on the same page) to figure out the total number of TOC pages. The problem is that every once in a while the last table print out very close to the end of the last page (but does not go over and no extra page is printed). When this happens writer.getPageNumber() returns the NEXT page number rather than the current page number the TOC is on. To test this I also tried getting the end page number, call document.newPage() and getting the page number again. The times when the numbers come out ok there will be a difference of one page. When the problem occurs (table is close to end of the page), I'll get the same page number before and after the document.newPage() call, both are 1 higher than they should be. This screws up all my page numbering and my reordering later on as well. Anyone have any ideas on this? It's been happening since back in the 1.x versions of iText (this is for Java).

External digest size

Eneko González Benito — 2008-12-03T17:52:50

Hi all, I've a problem and i think it's related with the external digest array size. I have had this code working until today: tSignatureAppearance.setExternalDigest(new byte[128], new byte[20], "RSA"); I've just tested this with a new certificate (from a new CA, which i think generates bigger keys (4 Kb?)) and it doesn't work; the acrobat reader says the signature is not valid. I have read in previous posts that the size of the buffer depends on the signature size and the hash. Is there a way i could make the array big enought so i don't have this problem? I have to work with keys of both sizes (2Kb and 4 Kb) and would like to know: a) If is there a way i can calculate the size necessary from the certificate. b) If i can use a size (lets say 1Kb) for the array so it should work with every certificate, independently of it's size (i don't know if you MUST use a 128 bytes lenght array when singing with a 2 Kb key, o if you CAN use a 128 bytes (or bigger, this must be the minimum) length array.

Eliminate white space in PdfPTable

Swapna Guntu — 2008-12-03T14:05:04

Hi, I am using iText for generating PDF documents. I am adding data to a cell in the table and the data comes from database. When a cell contains more data that fits the rest of the page, it gets displayed in the next page and I don't want to have any blank space in between the pages. I am displaying data using pharse. Is there any property that displays the text irrespective of size. Any suggestions/recommendations would be greatly appreciated. Thanks. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ iText-questions mailing list iText-questions< at >lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/itext-questions Buy the iText book: http://www.1t3xt.com/docs/book.php

Footer with Page Count and additional Information

geke — 2008-12-03T10:06:03

I have a footer where on the left side a text like "Project a, Date: and so on" and on the right side "Page x of y" should be. The problem is, that the y, the total amount of pages, also prints on the text on the left side of the footer. I only need it in the page information on the right side. Maybe someone can help me. The source is http://www.nabble.com/file/p20810009/TimeRecordPdfViewEvent.java TimeRecordPdfViewEvent.java

Embedding fonts for PDFA in searchable PDF

Benjamin Podszun — 2008-12-02T17:41:59

Hi there. I'm using itextsharp to do exactly what someone else was trying to do a week ago (just joined, otherwise I'd have answered of course). My code works fine for "normal" PDF files, that is without trying to create PDF/A files. It fails as soon as I add the snippets to make it a PDF/A at content.SetFontAndSize(font, fontSize); with a PDFXConformanceException, "All fonts must be embedded". Yes, sure. Makes sense. But actually I already want to embed the font in the first place. I'm pasting a slightly longer snipped for the guys that want to do the same, marking the possible cause with a huge/caps comment. Again: The code works as long as I don't try to create a PDF/A compliant PDF (i.e. the parameter to my method is false). Thanks in advance for any help! Ben private static void ConvertToPDF(RandomAccessFileOrArray sourceFile, string destinationImageFile, bool searchable, bool pdfAcompliant) { // Create the PDF document Document document = new Document(); PdfWriter pdfWriter = PdfWriter.GetInstance(document, new FileStream(destinationImageFile, FileMode.Create)); pdfWriter.StrictImageSequence = true; pdfWriter.SetFullCompression(); pdfWriter.SetLinearPageMode(); if (pdfAcompliant) { pdfWriter.PDFXConformance = PdfWriter.PDFA1B; } // POSSIBLE CAUSE HERE: // This is the font I'm using. It's only used for invisible rendering anyway // The "embedded" parameter is true, but Visual Studio shows me that the resulting // BaseFont instance's "embedded" member is set to false when I debug this? BaseFont font = BaseFont.CreateFont(BaseFont.HELVETICA, BaseFont.WINANSI, pdfAcompliant); // I do this for multiple pages, leaving the loop out here Image pageImage = SomeConversionMethod(); // Set the size of the next page to the image dimensions iTextSharp.text.Rectangle PageRectangle = new iTextSharp.text.Rectangle(pageImage.Width, pageImage.Height); document.SetPageSize(PageRectangle); // Compute the scaling factor for coordinate transformations double horizontalScaling = pageImage.ScaledWidth / pageImage.Width; double verticalScaling = pageImage.ScaledHeight / pageImage.Height; // Prepare/start the next page in the PDF document if (document.IsOpen()) { document.NewPage(); } else { document.Open(); if (pdfAcompliant) { // Copied verbatim from the itext mailing list, see: // http://article.gmane.org/gmane.comp.java.lib.itext.general/31582/ PdfDictionary outputIntent = new PdfDictionary(PdfName.OUTPUTINTENT); outputIntent.Put(PdfName.OUTPUTCONDITIONIDENTIFIER, new PdfString("sRGB IEC61966-2.1")); outputIntent.Put(PdfName.INFO, new PdfString("sRGB IEC61966-2.1")); outputIntent.Put(PdfName.S, PdfName.GTS_PDFA1); PdfICCBased ib = new PdfICCBased(ICC_Profile.GetInstance(Properties.Resources.ICC_Profile)); ib.Remove(PdfName.ALTERNATE); outputIntent.Put(PdfName.DESTOUTPUTPROFILE, pdfWriter.AddToBody(ib).IndirectReference); pdfWriter.ExtraCatalog.Put(PdfName.OUTPUTINTENTS, new PdfArray(outputIntent)); } } if (searchable) { // Grab the OCR Data SomePageStructure ocrPage = GetPageFromSomewhere(); if (ocrPage != null) { // Read all words in all lines foreach (Line ocrLine in ocrPage.Lines) { foreach (Word ocrWord in ocrLine.Words) { // Calculate the font size for the OCR rectangle bounds float fontSize = CalculateFontSize(font, ocrWord.Rectangle.Width * horizontalScaling, ocrWord.Data); // Special case: Some characters are non-printable: Continue with the next word if (fontSize < 0.1f) continue; // Write the text to the PDF, on the layer below the default content, invisble PdfContentByte content = pdfWriter.DirectContentUnder; content.BeginText(); // EXCEPTION BELOW content.SetFontAndSize(font, fontSize); // EXCEPTION HERE, font seems not to be embedded // EXCEPTION ABOVE content.SetTextRenderingMode(PdfContentByte.TEXT_RENDER_MODE_INVISIBLE); content.SetTextMatrix( (float)(ocrWord.Rectangle.Location.X * horizontalScaling), pageImage.ScaledHeight - (float)(ocrWord.Rectangle.Bottom * verticalScaling) ); content.ShowText(ocrWord.Data); content.EndText(); } } } } // Draw/add the image to the PDF page pageImage.SetAbsolutePosition(0, 0); document.Add(pageImage); if (pdfAcompliant) pdfWriter.CreateXmpMetadata(); document.Close(); } Can anyone help out? ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ iText-questions mailing list iText-questions< at >lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/itext-questions Buy the iText book: http://www.1t3xt.com/docs/book.php

Image size in ColumnText

native.human — 2008-12-01T21:11:01

I am using ColumnText.addElement to add an Image object that I have run scalePercent on. It seems to be ignoring my scaling and making the image the width of the entire column. Seems like it might have to do with text mode vs. compsite mode, but I think I'm in composite mode. My code looks like this, and previous to this code is a call to ct.go(), so there's nothing else in the column but the image at this point: imgGraph.scalePercent(50); imgGraph.setAlignment(Image.LEFT); /* * Add chart for simulated render */ ct.addElement(imgGraph); /* * Start new page if necessary. */ handleOrphans(ct, document, columnTop); /* * Add chart again, because handleOrphans only simulates * render. */ ct.addElement(imgGraph); /* * Actual render, handling paging as necessary */ handlePaging(ct, document, columnTop, "Highlight graph"); handleOrphans looks like this: protected void handleOrphans(ColumnText ct, Document document, float columnTop) throws DocumentException { /* * Position to render at. Default to position before the render. */ float position = ct.getYLine(); /* * Pretend to render column */ int status = ct.go(true); /* * If it doesn't all fit... */ if (ColumnText.hasMoreText(status)) { /* * Clear column contents in case there's content still in there. */ ct.setText(null); /* * Start new page */ document.newPage(); /* * Set position to top of page */ position = columnTop; } /* * Set position to top of page */ ct.setYLine(position); } and handlePaging looks like this: protected void handlePaging(ColumnText ct, Document document, float columnTop, String description) throws DocumentException { /* * Page count. */ int pageCount = 0; /* * Max out at 100 pages to prevent an infinite loop. */ final int maxPage = 100; /* * Render column */ int status = ct.go(); /* * If there's more text, start a new page and continue. */ while (ColumnText.hasMoreText(status) && pageCount < maxPage) { /* * Start new page */ document.newPage(); /* * Move column position to top of page */ ct.setYLine(columnTop); /* * Render again */ status = ct.go(); } }

epsg entry in gcs dictionary?

Matthias Uhler — 2008-12-01T16:03:46

hi, when i choose a wkt string for WGS84 as entry in a geographic coordinat system dictionary (iso 32000 supplement, p. 51) like this: dictionaryGCS.put(new PdfName("WKT"),new PdfString("GEOGCS[...]")); The georeferencing works great! Instead of using an wkt string I tried to change the entry to an EPSG-code: dictionaryGCS.put(new PdfName("EPSG"),new PdfNumber("4326")); //EPSG of wgs84 This doesn't work! I tried also other epsg codes without any success. Do you have any idea or hints how to put the code for a working PDF? Thank you, Matthias
