  • A light PDF viewer inside a webpage

    - by Jack
    Hello, which free PDF viewers are available to directly show a PDF file inside a webpage? I don't want to use Adobe Reader integration because I don't like it. I tried with Google Docs Viewer and it works fine but doesn't resize as I resize the page.. I would like to know if something quite light that can also be easily resized according to the page exists.. any suggestions?

  • 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?

  • Meta package / quick reference for string manipulation commands?

    - by Dylan McCall
    The latest version of the Scribes text editor lets us select some text, hit Alt+X, and then run an arbitrary command. For example, I can run the sort command and the selected text is replaced appropriately. This is quite useful but I am also not very well-versed in awk and the like. Is there something I can grab that will provide more of these commands like sort? Maybe a package with a whole bunch of handy, task-specific string manipulation commands?

  • 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.

  • 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!

  • 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.

  • Pro/con of using Angular directives for complex form validation/ GUI manipulation

    - by tengen
    I am building a new SPA front end to replace an existing enterprise's legacy hodgepodge of systems that are outdated and in need of updating. I am new to angular, and wanted to see if the community could give me some perspective. I'll state my problem, and then ask my question. I have to generate several series of check boxes based on data from a .js include, with data like this: $scope.fieldMappings.investmentObjectiveMap = [ {'id':"CAPITAL PRESERVATION", 'name':"Capital Preservation"}, {'id':"STABLE", 'name':"Moderate"}, {'id':"BALANCED", 'name':"Moderate Growth"}, // etc {'id':"NONE", 'name':"None"} ]; The checkboxes are created using an ng-repeat, like this: <div ng-repeat="investmentObjective in fieldMappings.investmentObjectiveMap"> ... </div> However, I needed the values represented by the checkboxes to map to a different model (not just 2-way-bound to the fieldmappings object). To accomplish this, I created a directive, which accepts a destination array destarray which is eventually mapped to the model. I also know I need to handle some very specific gui controls, such as unchecking "None" if anything else gets checked, or checking "None" if everything else gets unchecked. Also, "None" won't be an option in every group of checkboxes, so the directive needs to be generic enough to accept a validation function that can fiddle with the checked state of the checkbox group's inputs based on what's already clicked, but smart enough not to break if there is no option called "NONE". I started to do that by adding an ng-click which invoked a function in the controller, but in looking around Stack Overflow, I read people saying that its bad to put DOM manipulation code inside your controller - it should go in directives. So do I need another directive? So far: (html): <input my-checkbox-group type="checkbox" fieldobj="investmentObjective" ng-click="validationfunc()" validationfunc="clearOnNone()" destarray="investor.investmentObjective" /> Directive code: .directive("myCheckboxGroup", function () { return { restrict: "A", scope: { destarray: "=", // the source of all the checkbox values fieldobj: "=", // the array the values came from validationfunc: "&" // the function to be called for validation (optional) }, link: function (scope, elem, attrs) { if (scope.destarray.indexOf(scope.fieldobj.id) !== -1) { elem[0].checked = true; } elem.bind('click', function () { var index = scope.destarray.indexOf(scope.fieldobj.id); if (elem[0].checked) { if (index === -1) { scope.destarray.push(scope.fieldobj.id); } } else { if (index !== -1) { scope.destarray.splice(index, 1); } } }); } }; }) .js controller snippet: .controller( 'SuitabilityCtrl', ['$scope', function ( $scope ) { $scope.clearOnNone = function() { // naughty jQuery DOM manipulation code that // looks at checkboxes and checks/unchecks as needed }; The above code is done and works fine, except the naughty jquery code in clearOnNone(), which is why I wrote this question. And here is my question: after ALL this, I think to myself - I could be done already if I just manually handled all this GUI logic and validation junk with jQuery written in my controller. At what point does it become foolish to write these complicated directives that future developers will have to puzzle over more than if I had just written jQuery code that 99% of us would understand with a glance? How do other developers draw the line? I see this all over Stack Overflow. For example, this question seems like it could be answered with a dozen lines of straightforward jQuery, yet he has opted to do it the angular way, with a directive and a partial... it seems like a lot of work for a simple problem. Specifically, I suppose I would like to know: how SHOULD I be writing the code that checks whether "None" has been selected (if it exists as an option in this group of checkboxes), and then check/uncheck the other boxes accordingly? A more complex directive? I can't believe I'm the only developer that is having to implement code that is more complex than needed just to satisfy an opinionated framework.
