• Get the layout mode (landscape or portrait) of a pdf from php/linux

  - by Jonathan Hendler

  Given a PDF, how can one get the layout mode of a PDF (or relative width/height) using a PHP lib or linux command line tool? Using http://www.tecnick.com/public/code/cp%5Fdpage.php?aiocp%5Fdp=tcpdf which can set this variable on new PDFs, but for existing pdfs from adobe. Thought of converting pdfs to ps, or using gs in some other way - like converting it to an image first, and getting the width and height of that. Is this the best way?

• Automated obscuring of PDF content

  - by Manabenz

  Hello I'm looking for a tool which will allow me to automate the task of obscuring a certain section of content contained within a PDF. The PDF content is essentially one big image which contains some sensitive information, and it is this information we need to ensure is not readable. Any tips for where I should start looking for such a solution? Many thanks M

• How to Convert HTML to PDF Using PHP?

  - by Meng Longlong

  PDF or Portable Document Format is a popular file type that is often used for online documents. It's great for distributing downloadable written content, and is frequently used by governments and businesses alike. Because it's a format that's familiar to all, many applications allow the user to convert other document types to the PDF format. PHP is one programming language that has a built-in ability to convert to PDF. PHP scripts can be used to transform file types such as HTML into PDF files.

• What package is meant to replace thinkfinger in 11.10?

  - by misterhaan

  My laptop has a fingerprint reader that until 11.10 I used via thinkfinger. That package is no longer in the repositories, but I assume there’s a different package meant to support fingerprint readers in thinkfinger’s place. What is the recommended fingerprint reader package? Should I just find thinkfinger on my own and use that instead? Here’s my reader’s lsusb output: Bus 003 Device 002: ID 0483:2016 SGS Thomson Microelectronics Fingerprint Reader

• Converting PDF to images using ImageMagick.NET - how to set the DPI

  - by Avi Pinto

  Hi, I'm trying to convert pdf files to images. ImageMagick is a great tool, and using the command line tool gets me desired result. but i need to do this in my code, So added a reference to http://imagemagick.codeplex.com/ And the following code sample renders each page of the pdf as an image: MagickNet.InitializeMagick(); using (ImageList im = new ImageList()) { im.ReadImages(@"E:\Test\" + fileName + ".pdf"); int count = 0; foreach (Image image in im) { image.Quality = 100; image.CompressType = mageMagickNET.CompressionType.LosslessJPEGCompression; image.Write(@"E:\Test\" + fileName + "-" + count.ToString() + ".jpg"); ++count; } } The problem: IT LOOKS LIKE CRAP the rendered image is hardly readable. the problem i realized is it uses the default 72 DPI of ImageMagick. and i can't find a way to set it(96dpi or 120dpi gives good results) via the .Net wrapper. Am I missing something , or there is really no way to set it via this wrapper? Thanks

• PHP and C# communication on IIS7 (to generate dynamic PDF)

  - by David Murdoch

  Background: I couldn't find any decent free HTML to PDF conversion utilities in C#. There are 100s of them for PHP with extensive documentation, support, and CSS support. So I am using html2ps and html2pdf (php). I have PHP 5.2 installed on IIS7 and its working beautifully to create PDFs. I have the following in getPDF.aspx <!-- Output the header --> <DM:header runat="server" ID="header" /> <asp:Placeholder id="content" runat="server" /> <!-- Output the footer --> <DM:footer runat="server" ID="footer" /> and in getPDF.aspx.cs: protected void Page_Load(object sender, EventArgs e){ // AddContentControl simples adds a controls to the content Placeholder. AddContentControl("controls/page1.ascx"); AddContentControl("controls/page2.ascx"); AddContentControl("controls/page3.ascx"); } and in generatePDF.php: <?php /* ... includes and stuff here ... */ $data = "THE HTML GOES HERE!"; // creates the PDF from the $data and Outputs the created file. convert_to_pdf($data); ?> -- getPDF.aspx works perfectly...except the output is HTML. So how can I get getPDF.aspx to output its HTML as PDF generated by generatePDF.php?

• I seek a PDF paginator

  - by Cameron Laird

  More precisely, I need software that will allow me to consume existing PDF instances, decorate them with page numbers, or page-number-like writing, then write them back to the filesystem. I'll happily pay for an application, or program it myself. I almost certainly require the software run under Linux (Ubuntu, more specifically). iText comes close. iText certainly can read existing PDF instances. While iText is, for this purpose, only a library, and requires me to program a tiny amount to specify where on the page the numbers should appear, I'm happy to do that. I hesitate with iText only because the latest iText license is a headache at certain government agencies (in practice, I'd probably request and pay for a special license), and because, over the last few years, I've observed cases where iText doesn't appear to keep up with the standard, that is, it has more troubles than I expect reading PDFs observed "in the wild". Similarly, every other possibility I know has at least one difficulty: ReportLab would likely require a disproportionate licensing fee for the small value it provides in this situation, and so on. This application requires no particular sophistication with Unicode, fonts, ... I recognize there are plenty of executables and libraries that do some or all of what I require. I welcome any tips on software that is reliable, generally current with PDF practice, flexible/programmable/configurable/..., and "automatable". In the absence of any new insight, I'll likely go with a specific open-source library I don't want to mention now for which I've already contracted enhancements, or perhaps revisit iText.

• Streaming PDF via invocation of HTTPHandler using $.get into object element

  - by mythicdawn

  What I am trying to do is invoke an HTTPHandler via the $.get method of jQuery which will stream back a PDF and display it in a web page using an object element. My previous method of setting the src attribute of an IFrame to be the result of a handler invocation works, but I would like cross-browser completion notification, so have moved to using $.get(). Sample code: function buttonClick() { $.get("/PDFHandler.ashx", {}, function(data, textStatus, XMLHttpRequest) { var pdfObjectString = "<object data='' type='application/pdf' width='600' height='600'></object>"; var pdfObject = $(pdfObjectString); pdfObject.attr("data", data); $("#container").append(pdfObject); }); As you can see, I am attempting to stick the 'data' variable into an object element. This is not working (no error, PDF just doesn't display), presumably because the data that comes back is binary, yet the attr() method expects a string (I think). My question is thus: how can I invoke an HTTPHandler via $.get and somehow assign the data from the callback to the data attribute of an object?

• PDFBox: Problem with converting pdf page into image

  - by user552910

  My mission is pretty simple: converting every single page of a pdf file into images. I tried using icepdf open source version to generate the images but they don't generate the image with the correct font. So I start using PDFBox instead. The code is the following: PDDocument document = PDDocument.load(new File("testing.pdf")); List<PDPage> pages = document.getDocumentCatalog().getAllPages(); for (int i = 0; i < pages.size(); i++) { PDPage singlePage = pages.get(i); BufferedImage buffImage = convertToImage(singlePage, 8, 12); ImageIO.write(buffImage, "png", new File(PdfUtil.DATA_OUTPUT_DIR+(count++)+".png")); } The font looks good, but the pictures within the pdf file look fainted out (See the attachment). I look into the source code but I still have no clue how to fix it. Do you guys have any idea what's going on? Please help. Thanks!!

• Convert SVG to PDF

  - by Adrian Smith

  How would one go about converting a SVG file to a PDF programatically? (I need to alter the SVG in certain respects before generating the PDF so simply pre-converting it using a tool won't be sufficient.) Ideally using Java but Perl or PHP would be fine too. Obviously I am basically considering Apache FOP and Batik with Java. However no matter how long I search I cannot find a simple introduction on how to do it. Things like SVGConverter have descriptions like "Defines the interface for classes that are able to convert part or all of a GraphicContext", but I don't really know what that means. I have this feeling there must be an API to do this quite simply, provided by FOP or Batik, but I'm just not able to find it at the moment (or perhaps it really doesn't exist.) In terms of the supported SVG features I need, the file has some paths which are filled with some linear gradients. Ideally if I could pass the SVG in as a DOM Document that would be ideal; then I would load my template SVG file, change it as specified by the user, and then generate the PDF.

• How Do I Export Pages from Browser with Embedded Hyperlinks?

  - by Volomike

  Made a sad discovery today. I have Ubuntu 10.04 LTS. My client is in the ad business and she had a marketing competition task for me. She wanted me to visit websites of the competitors, and export the home pages as PDF. However, she wanted me to do so with embedded hyperlinks. As it turns out, Firefox (and even the latest Chrome) on Ubuntu 10.04 LTS do not embed hyperlinks in PDF web page exports. Sure, there are several Chrome and FF plugins that let you export as PDF, but what these do is connect to the URL remotely, generate the PDF remotely, and then force a download in your browser to download it from a remote location. That's not good for me, though, because some of these competitor pages require an initial login. That means that all I get back on the PDF printing from these FF or Chrome plugins is a login page. Is there a way to get around this problem, to fix the broken PDF printer on Ubuntu 10.04?

• Converting .docx to pdf (or .doc to pdf, or .doc to odt, etc.) with libreoffice on a webserver on the fly using php

  - by robertphyatt

  Ok, so I needed to convert .docx files to .pdf files on the fly, but none of the free php libraries that were available let me do it on my server (a webservice was not good enough). Basically either I needed to pay for a library (and have it maybe suck) or just deal with the free ones that didn't convert the formatting well enough. Not good enough! I found that LibreOffice (OpenOffice's successor) allows command line conversion using the LibreOffice conversion engine (which DID preserve the formatting like I wanted and generally worked great). I loaded the latest version of Ubuntu (http://www.ubuntu.com/download/ubuntu/download) onto my Virtual Box (https://www.virtualbox.org/wiki/Downloads) on my computer and found that I was able to easily convert files using the commandline like this: libreoffice --headless -convert-to pdf fileToConvert.docx -outdir output/path/for/pdf I thought: sweet...but I don't have admin rights on my host's web server. I tried to use a "portable" version of LibreOffice that I obtained from http://portablelinuxapps.org/ but I was unable to get it to work on my host's webserver, because my host's webserver didn't have all the dependencies (Dependency Hell! http://en.wikipedia.org/wiki/Dependency_hell) I was at a loss of how to make it work, until I ran across a cool project made by a Ph.D. student (Philip J. Guo) at Stanford called CDE: http://www.stanford.edu/~pgbovine/cde.html I will let you look at his explanations of how it works (I followed what he did in http://www.youtube.com/watch?feature=player_embedded&v=6XdwHo1BWwY, starting at about 32:00 as well as the directions on his site), but in short, it allows one to avoid dependency hell by copying all the files used when you run certain commands, recreating the linux environment where the command worked. I was able to use this to run LibreOffice without having to resort to someone's portable version of it, and it worked just like it did when I did it on Ubuntu with the command above, with a tweak: I needed to run the wrapper of LibreOffice the CDE generated. So, below is my PHP code that calls it. In this code snippet, the filename to be copied is passed in as $_POST["filename"]. I copy the file to the same spot where I originally converted the file, convert it, copy it back and then delete all the files (so that it doesn't start growing exponentially). I did it this way because I wasn't able to make it work otherwise on the webserver. If there is a linux + webserver ninja out there that can figure out how to make it work without doing this, I would be interested to know what you did. Please post a comment or something if you did that. <?php //first copy the file to the magic place where we can convert it to a pdf on the fly copy($time.$_POST["filename"], "../LibreOffice/cde-package/cde-root/home/robert/Desktop/".$_POST["filename"]); //change to that directory chdir('../LibreOffice/cde-package/cde-root/home/robert'); //the magic command that does the conversion $myCommand = "./libreoffice.cde --headless -convert-to pdf Desktop/".$_POST["filename"]." -outdir Desktop/"; exec ($myCommand); //copy the file back copy("Desktop/".str_replace(".docx", ".pdf", $_POST["filename"]), "../../../../../documents/".str_replace(".docx", ".pdf", $_POST["filename"])); //delete all the files out of the magic place where we can convert it to a pdf on the fly $files1 = scandir('Desktop'); //my files that I generated all happened to start with a number. $pattern = '/^[0-9]/'; foreach ($files1 as $value) { preg_match($pattern, $value, $matches); if(count($matches) ?> 0) { unlink("Desktop/".$value); } } //changing the header to the location of the file makes it work well on androids header( 'Location: '.str_replace(".docx", ".pdf", $_POST["filename"]) ); ?> And here is the tar.gz file I generated I generated with CDE. To duplicate what I did exactly, put the tar.gz file in a folder somewhere. I will call that folder the "root". Make a new folder called "documents" in the "root" folder. Unpack the tar.gz and run the php script above from the "documents" folder. Success! I made a truly portable version of LibreOffice that can convert files on the fly on a webserver using 100% free, open source software!

• WinForm PDF viewer with programatic search functionality

  - by Anthony Shaw

  We are currently using PDFTron's PDFView WinForm control to view PDF's in a WinForm application. I can load the file and search the file to highlight a certain text value. We have run into an issue where we have expired our trial license period and do not wish to shell out the $900/seat licensing on 15-20 computers. Does anybody know if the ActiveX Adobe Reader control can support the searching functionality programatically? I've tried that and the FoxIt Reader OCX control and neither seem to have this feature exposed (unless it's hidden really well) Does anybody have any suggestions for other freeware/open source viewers, or less-expensive viewers? TIA!

• Using Javascript in Adobe Reader

  - by godleuf

  Hi, I am currently using the following script for a few documents: var pp = this.getPrintParams(); pp.interactive = pp.constants.interactionLevel.automatic; this.print(pp); How do I add another command, say document.close() so that it reads the print function and then follows the close document last? Do I simply add the close command right after the print command so it would read var pp = this.getPrintParams(); pp.interactive = pp.constants.interactionLevel.automatic; this.print(pp); document.close(); Thanks.

• optimal folder structure for storing 100k files on a USB drive

  - by cherouvim

  I need to store 100k files (around 40GB) in a USB drive. Each file has a unique int id (e.g 45000). Option one is to put all files in a single folder: root/ root/1.pdf root/2.pdf root/3.pdf ... root/567.pdf root/568.pdf root/569.pdf ... root/10001.pdf root/10002.pdf root/10003.pdf ... root/99998.pdf root/99999.pdf root/100000.pdf Option two is to create a [1-9][0-9]* folder hierarchy based on that id: root/ root/1/file.pdf root/2/file.pdf root/3/file.pdf ... root/5/6/7/file.pdf root/5/6/8/file.pdf root/5/6/9/file.pdf ... root/1/0/0/0/1/file.pdf root/1/0/0/0/2/file.pdf root/1/0/0/0/3/file.pdf ... root/9/9/9/9/8/file.pdf root/9/9/9/9/9/file.pdf root/1/0/0/0/0/0/file.pdf Which option will scale better? I can understand that the second option will require tons of folders but each folder will at most contain 10 folders and 1 file. Maintenance will not be an issue since everything will be controlled by an application. Note that this is a USB drive on linux and based on the above I'd also like to know whether I should go with FAT32 or NTFS.

• Is there a way to allow continuous scrolling in Adobe Reader?

  - by RLH

  I am having to read through a MASSIVE (1000+ page) PDF specification in Adobe Reader X (version 10). It has always bugged me that if you scroll to the edge of a page, the Reader automatically jumps to the top of the next page. Is there away to cut this off so that when I reach the bottom of one page, the edge of the page meets the top of the next page and I can see a half-page of both the last and next page? I know that MS Word can and does behave this way. Can I change a setting to scroll the document in this manner in Adobe Reader?

• What RSS Reader can handle item-updating (JIRA search) feeds?

  - by Stephen

  Thunderbird is a good rss reader in terms of being able to connect successfully to jira authenticated search feeds (where evolution-rss and Liferea can't), but really sucks when it comes to updating. A Jira search feed will give a link id to http://jira/browse/[ticket no], and if that ticket/feed-item is updated, thunderbird refuses to update it - it already has it! (even though the item date does not match). Also, if you delete the ticket update, it will never show up again for that news account. Has anybody found an RSS reader that can work with JIRA/updating RSS items? Note: this is not the same as Jira activity feeds - those work great, as each update has a unique item id To replicate: Grab a search (any search) Get it into your rss reader Read an item, modify the linked ticket Update rss and see if the ticket bumps to most recent and unread or, generically: Get an rss feed (from your hard drive?) Modify an item in the middle changing the content, the date, and moving it to the top Update rss and see if the ticket bumps to most recent and unread

• EMBED vs. OBJECT

  - by JayhawksFan93

  Which is the right/best tag to use in my HTML file when I want to display the Adobe PDF viewer? Right now I'm using the code below, but there are weird side effects (e.g. it seems to steal the starting focus that I've set to another INPUT text box; it doesn't seem to play real well with the jQueryUI Resizeable class; etc.) <embed src="abc.pdf" type="application/pdf" /> Could I even do the same thing with the OBJECT tag? Are there advantages/disadvantages to using one tag vs. the other?

• Merge FDF data into a PDF file using PHP

  - by James

  Is it possible to merge FDF data with a PDF file using PHP alone? Or is there no option but to use a 3rd party command line tool to achieve this? If that is the case can someone point me in the direction of one? I am currently outputting the FDF file to the browser in the hope that it will redirect the user to the filled in PDF but for some people that is not the case. The FDF contents is being output to the screen, even though I am using header('Content-type: application/vnd.fdf');
