How To Create Your Own Personal Document Viewer (Like Scribd or Google Books)

Submitted by on January 3, 2010 – 12:35 am 40,735 views 25 Comments

Overview

Like most people, I have a large number of personal documents in a variety of formats (PDF, Excel, Word, RTF, PowerPoint, etc.). For the typical user, organizing these documents in a ‘My Documents’ folder and having MS Office/Open Office/Adobe Acrobat installed simply gets the job done. However, I’ve been looking for some sort of “Web 2.0″ solution to view my documents while I’m on the go. And, since my knowledge manager is web-based, I’d like a way to browse and embed personal documents directly in my wiki without needing any special software.

I’ve been impressed with services like Scribd (think YouTube for Documents). Most people have probably already used Scribd, but in case you haven’t, this service allows you to upload your documents (variety of formats supported) and view them online in Flash format. The beauty of this service is that you can also share documents and embed directly inside you website/blog/wiki. While this works great for sharing certain types of documents, it’s not really appropriate for uploading my entire collection of documents (especially since many contain personal information). So, I decided to figure out how to create my own hosted document/book viewer like Scribd or Google Books.

Example

The following embedded document browser was actually fairly straight forward to make. In a nutshell, the viewer takes a PDF file that is converted to Flash (using SWFTools – pdf2swf), and then uses an open source flash viewer called FlexPaper to help with navigation.

The navigation bar is fairly straight forward. You can page up/down, go directly to a given page, zoom, print, and even select a thumbnail mode. It does currently lack the ability to view full screen, search (Search was JUST added to version 1.1) or select text, so I create additional option to view in HTML (using wvHtml) and view the frame full screen.

Open Source To The Rescue

When I first start exploring ways to view all my docs in a web interface, I didn’t initially focus on flash. I figured it would be too difficult to have the end product look like Scribd (I was way wrong). So, I evaluated a number of Linux command-line utilities to convert documents on the fly. The following is a decent list of applications that can help with any of your conversion needs:

  • wvWare – A library for converting Word docs. The utility I used most was wvHtml to convert from .doc directly to .html.
  • xlHtml – Converts Excel spreadsheets to HTML.
  • PDFtoHtml – Converts PDF documents to HTML
  • UnRTF – Converts RTF to text or HTML
  • SWFTools – A collection of utilities to generate and work with SWF (Flash) files

There are apparently some ways to convert between various formats using Open Office on the command-line (e.g. JODConvert, PyODConverter, Unoconv, etc.). However, I haven’t yet spent time evaluating these approaches since my current setup seems to be working pretty well.

DocBrowser Project

I put up a very preliminary Document Browser prototype at http://eric-blue.com/projects/docbrowser/. The interface uses JQuery and JQueryFileTree to make entire document folder available for browsing just like Windows Explorer.

The doc viewer pane uses the Flash-based interface like the iFrame above for all .PDF docs. And, the conversion script will render the output in HTML according to the doc type (.doc, .xls, .rtf) using the tools listed above. I’ve even added support for Mind Manager mindmaps using my web-based mindmap viewer to do conversions into Freemind flash on the fly.

Overall, I’m happy with the end result. I’ve setup a customized version of the document browser to run on my personal web server at home. I can now successfully view my documents from my Laptop while I’m on the road, and I’ve been able to embed documents directly in my wiki so I don’t have to spend time hunting for the right doc.

  • Nice work!
    Good seeing FlexPaper coming to use. I actually just released version 1.1 which _does_ contain a search function! :-)

  • ericblue76 says:

    Erik, thanks and perfect timing! Nothing like getting in touch in real-time AND having a new version of FlexPaper with just the feature I need. :)

  • ericblue76 says:

    I also added support for directly embedded Google Books. I added a custom handler for .url extensions that will embed the book url (e.g. http://books.google.com/books?id=88U6hdUi6D0C) inside an iframe.

    I also wrote a quick little script that parses your Google Books library XML file, grabs the title and URL and outputs to the URL file. So now the document browser can combine you physical and ‘virtual’ docs hosted by Google. Pretty cool.

    Hi Eric,

    This is an excellent contribution, and thank you for mentioning Vuzit (my company) in your links. I remember years ago doing surveys like this, and would have loved to stumble on something like this at that time. It’s amazing how far different combinations of the open source tools can go these days!

    I’ll just mention a couple of things about Vuzit that might be interesting to others. Vuzit is a development platform we sell to other online businesses that provides document sharing, control, and analytics features that are presently unavailable in any other products. As such, it’s not free! We do open source and host all of our client libraries on github (PHP, Ruby, .NET, Java, etc) however. Another major difference is that it’s AJAX and web service based (ie. no Flash/SWF) so you can build your own front-end if you wish.

    Thanks! -Chris (Vuzit co-founder and CTO)

  • Glad to see xlhtml being put to use. I put quite a bit of effort into the program. :)

    I discovered recently that any PDF can be viewed via Google Docs by prepending the PDF’s URL with http://docs.google.com/viewer?url= .

    Hey eric, that’s really a great contribution.
    Now a days I use the viewer made by macromedia i.e flashpaper. I need some help, I just wanted to show the pages in two-up view, like the Adobe reader i.e we can see two pages at a time. See if you can help me with it or just give me any other option which would include the two-up page view and exclude download or save or print.
    Hoping for a soon reply.

    Thanks and Regards,

  • LeeNukes says:

    Anyone know why when I set PrintEnabled : false it doesn’t work?

    The document still has the print button on the toolbar. A way to remove that would be good.

    Anyone know anything about watermarks too?

  • Hi Erik,
    Have you posted your work online to download (the source). I’d love to try this on my personal server as well.

    Thanks!

  • ericblue76 says:

    Hi Travis,

    I created a follow-up post with a link to the download. Bear in mind it’s nothing fancy (e.g. some weekend hacking) but gets the job done.

  • Hi,

    Thank you for your post it is a nice blog. You have describe the large number of document formats and applications are available in my documents. You can also distribute your thoughts and ideas on Document Viewer

  • epistasis says:

    Hi Eric,

    I was wondering if you could let us know how storing the document in your wiki works?

    Do you have to duplicate things? A copy in the wiki, and a copy in a file system so that the document browser displays how it does?

    I’m looking for a way to store, tag & retrieve/view .pdf/.docx files.

    I’ve been looking into docmgr.org but I’m not sure how I could integrate it with MediaWiki :(

  • Michael Lynn says:

    Thanks – great article. I’ve created an article which explains how to do something very similar using ExtJS / Javascript. My approach leverages a perl script to parse a csv file containing the details of your documents. This script builds the JSON required by the treeview control. There’s a demo at http://mlynn.org/docviewer-1.0/ and the article with downloadable examples is at http://www.mlynn.org/2012/01/create-a-simple-document-viewer-with-extjs/

    Thanks again!
