  • Can I flip the coordinate system without flipping text in iTextSharp?

    - by I. J. Kennedy
    I have some chart-creating code written for a coordinate system in which a y-coordinate of 0 is the top of the page. We are now converting to iTextSharp, which uses the conventional system from mathematics where a y-coordinate of 0 is the bottom of the page. There are many calculations involved in producing the chart and I'd like to not mess with those calculations. I can partially "fix" the problem by transforming iTextSharp's coordinate system like this: pdfContentByte.ConcatCTM(1f, 0f, 0f, -1f, 0f, pdfDoc.PageSize.Height); This works great for lines, rectangles, and circles, but the text is now upside down! Is there a way to remedy this, using SetTextMatrix or otherwise?

  • tcpdf - HTML table showing up way too small

    - by LinuxGnut
    Hi folks. I'm using tcpdf (http://www.tcpdf.org/) to generate PDFs of some tables and images. The images are loaded without an issue, but I'm having issues with the writeHTML() function. I can't seem to control the font sizes or table width/height through the HTML, so I end up with a tiny, tiny, tiny table that you have to print of and squint at to even attempt reading. I've tried editing the table itself, CSS, even putting the table itself inside an h1, but nothing is changing the font size. I have the font size in tcpdf set to 16, but this also has no affect. Has anyone else run into this issue?

  • Anyone able to translate sIFR into AS3 (for hyphenation and with the help of a converter)?

    - by Murat Bezel
    One thing asked for a lot with sIFR is hyphenation. Now I almost solved it with integrating Hyphenator.as http://vis4.net/blog/2010/05/as3-hyphenation/. The only problem is that Hyphenator.as is written in AcionScript 3, while sIFR is in ActionScript 2. I found an AS2 to AS3 converter www.5etdemi.com/blog/archives/2006/11/as2-to-as3-converter-createtextfield-geturl-handling/ but the result examples.bezel.be/sIFR-as3.as is not working yet. Anyone able to contribute to making hyphenation work in sIFR? (Sorry for the links, but weirdly I am only allowed to post one link. Really weird.)

  • Is Prince the best way to create PDFs in Ruby on Rails?

    - by Angela
    After several Google searches, it appears that the way to create PDFs in Rails from HTML and CSS (versus a new markup language) is to use Prince. With licensing at $3800 for my non-big-commercial app, I'm wondering if this is, in fact, consensus or people have an alternative they can share the whats and hows.

  • Write large PDFs with Java sequentially

    - by Benjamin Muschko
    I am looking for a Java library that let's you write large PDFs sequentially with a minimum amount of memory. Most of the libraries I had a look at has to build up the document in memory first before you can actually write it. The problem I have to deal with are OutOfMemoryErrors. It would be great if I could flush the writer programmatically whenever needed e.g. for each page. Does anyone have any recommendations? I need something with a license along the lines of the LGPL (so not the GPL or the Affero GPL that iText uses).

  • Java library for converting Word documents to PDFs or images

    - by mieze
    Hey there What I need to do is convert Microsoft Word .doc files to PDFs or images. This has to occur in Java. I have done a fair bit of investigation already. I've tried Davisor Publishor but it doesn't give me the accuracy that I need - for instance text overlapping in the output document. Adobe has something called LiveCycle. Anyone tried this? It looks quite massive and a bit of overkill (its an "integrated server solution"). Sounds expensive. Saying that, it doesn't have to be free, or cheap. Even if you just know some names, please shout them my way. Many thanks in advance. Doug

  • iTextSharp Overlay Image

    - by pennylane
    Hi guys I have an instance where I have a logo image as part of some artwork.. If a user uploads a new logo I have a form field which is larger than the default logo. I then use that form field to position the new image. The problem is I need to set the background colour of that form field to white so that it covers the old logo in the event that the new image is smaller than the old logo.. what I have done is: foreach (var imageField in imageReplacements) { fields.SetFieldProperty(imageField.Key, "bgcolor", iTextSharp.text.Color.WHITE, null); fields.RegenerateField(imageField.Key); PdfContentByte overContent = stamper.GetOverContent(imageField.Value.PageNumber); float[] logoArea = fields.GetFieldPositions(imageField.Key); if (logoArea != null) { iTextSharp.text.Rectangle logoRect = new iTextSharp.text.Rectangle(logoArea[1], logoArea[2], logoArea[3], logoArea[4]); var logo = iTextSharp.text.Image.GetInstance(imageField.Value.Location); if (logo.Width >= logoRect.Width || logo.Height >= logoRect.Height) { logo.ScaleToFit(logoRect.Width, logoRect.Height); } logo.Alignment = iTextSharp.text.Image.ALIGN_LEFT; logo.SetAbsolutePosition(logoRect.Left, logoArea[2] + (logoRect.Height - logo.ScaledHeight) / 2); // left: logoArea[3] - logo.ScaledWidth + (logoRect.Width - logo.ScaledWidth) / 2 overContent.AddImage(logo); } } The problem with this is that the background colour of the field is set to white and the image then doesn't appear.. i remove the SetFieldProperty and RegenerateField commands and the image replacement works fine.. is there a way to set a stacking order on layers?

  • Is the google docs embeddable previewer out of beta and will it have an have an API?

    - by Jonathan Hendler
    https://docs.google.com/viewer is awesome, but there are some customizations I need to make, and documentation would be helpful. Discovered here http://googlesystem.blogspot.com... . Haven't seen any public documentation that would help. http://code.google.com/apis/documents/overview.html covers the Google docs - where the above is more a clone of the Google Books previewer http://books.google.com/books .

  • Python 3-compatibe HTML to text converter preserving basic structure under permissive licence?

    - by hawk64
    I am looking for a relatively simple HTML to text converter which displays links and works on strings. So far I have tried lynx but performance is too bad, html2text which gives weird and verbose markdown output and is under GPLv3 which is too restrictive for my (BSD-licensed) project, http://effbot.org/librarybook/formatter-example-3.py using htmllib.HTMLParser with formatter.AbstractFormatter and a custom writer, however htmllib.HTMLParser is drpeceated and has been removed from Python 3. So is there any simple, performant, Python 3-compatible HTML to text converter under a permissive license such as MIT/BSD/Apache and the like? Edit: I dont just need something to strip HTML-Tags but also to preserve the basic structure of the HTML, that is output that somewhat resembles that of Lynx.

  • Online OCR website for processing an entire pdf file at one time?

    - by Tim
    I am looking for an online OCR website for processing a multi-page pdf file at one time. Free preferably. I know http://www.newocr.com/. If I am correct, it can only OCR one page at a time, by manually clicking "Preview" and then clicking "OCR" for each page. After each page is OCRed, I have to copy out the text result manually too. If my pdf file has 30~ pages, it will be tedious to repeat the above process for each page. I wonder if there is some other online websites that OCR a whole pdf file, without asking me for manual operation? Thanks!

  • How to enlarge a .PDF document to better show it in a Kindle 6"?

    - by Gus
    I have a kindle 6". The problem is that I often read pdf files that are technical, therefore, it doesn't get converted very well to kindle's native format (for example, code blocks get messed, and things like that). When I view the pdf page, it's very small to read easily, so I have to rotate the screen to a horizontal position in order to see it better, but my page get divided. But some documents would be easy to read in vertical position if I had the chance to enlarge the font size a little bit in a external pdf editor, therefore enabling the reading in the vertical orientation. Has anybody had the same situation? Is there a solution for that?

  • Microsoft Office Compatibility Pack "The converter failed to open the file" error & "This is a pre-release version"

    - by HaydnWVN
    What issues have people encountered with older OS's (2000, XP) and olders versions of Microsoft Office (2000, XP, 2003) with the 'Microsoft Office Compatibility Pack'? I have a couple of Windows 2000 client PC's encountering different errors when attempting to open .docx or .xlsx documents, some with Office XP and the others with Office 2003. Reading through forums it appears that the different versions of the compatibility pack, not all were compatible with Windows 2000 (versions 3 & 4 are not). There are also Service Packs for the Compatibility Pack. With these Windows 2000 clients, it seems i need the Compatibility Pack version 2, then to install the Service Packs, yet i'm unable to find a link for version 2 of it. First error message: "This is a pre-release version of the Compatibilty Pack and can open pre-release Office 2007 files only." Is solved below. Second error message: "The converter failed to open the file." My troubleshooting is still on-going.

  • How to suppress the unsolicited footer when converting HTML -> PDF with Acrobat?

    - by gojira
    I often convert & combine (via contextmenu) HTML pages to PDF using Acrobat (not Acrobat Reader). I use Adobe Acrobat Pro 9 Extended, version 9.1.2. The converted PDFs always have the full path of the original file on the bottom of the PDF-page, also they have an additional header line with the document. I need to suppress that. I do not want the unsolicited header and footer in the resulting PDF files as they are a pain to reomve manually, with a certain page count per document it becomes impossible. Is it possible to suppres that and if, how?

  • How to calculate the correct image size in out pdf using itextsharp ?

    - by MK
    I' am trying to add an image to a pdf using itextsharp, regardless of the image size it always appears to be mapped to a different greater size inside the pdf ? The image I add is 624x500 pixel (DPI:72): And here is a screen of the output pdf: And here is how I created the document: Document document = new Document(); System.IO.MemoryStream stream = new MemoryStream(); PdfWriter writer = PdfWriter.GetInstance(document, stream); document.Open(); System.Drawing.Image pngImage = System.Drawing.Image.FromFile("test.png"); Image pdfImage = Image.GetInstance(pngImage, System.Drawing.Imaging.ImageFormat.Png); document.Add(pdfImage); document.Close(); byte[] buffer = stream.GetBuffer(); FileStream fs = new FileStream("test.pdf", FileMode.Create); fs.Write(buffer, 0, buffer.Length); fs.Close(); Any idea why on how to calculate the correct size ?
