A DIY PDF Reader

Every few months I have to clean up my desktop computer as dust gets stuck in the CPU fan and it gets hot and slow and loud and annoying! A few days ago I snapped and decided to phase out the desktop and made my laptop as main machine. Even though I love making a fresh start on a new computer it comes with re-installing a bunch of stuff.

One missing thing that made itself obvious at the very start was a PDF reader. So far I’ve always been disappointed with PDF viewers. They are too bloated with unnecessary features and they always try to install a browser toolbar or an anti-virus trial.

My DIY PDF Reader

I started looking into my options to build my own PDF viewer and fortunately didn’t have to look too much. SyncFusion is offering a free license to their products for indie developers and small startups. I used their great wizard control in a past project (Image2PDF) so I first checked if they had something for me. Turns out they have exactly everything I needed wrapped in an easy to use control. Their WPF suite comes with a PdfViewerControl. It supports standard navigation and zooming functions which is pretty much what I need from a PDF viewer. So all I had to do was a start a new WPF project, drag & drop PdfViewerControl and run!

The whole XAML code looks like this:

<Window
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
        xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
        xmlns:local="clr-namespace:PdfViewer"
        xmlns:PdfViewer="clr-namespace:Syncfusion.Windows.PdfViewer;assembly=Syncfusion.PdfViewer.WPF" x:Class="PdfViewer.MainWindow"
        mc:Ignorable="d"
        Title="Easy PDF Viewer" 
        WindowState="Maximized">
    <Grid>
        <PdfViewer:PdfViewerControl  HorizontalAlignment="Stretch" VerticalAlignment="Stretch"/>
    </Grid>
</Window>

And for my 5 minutes, this is the application I got:

Conclusion

If I need more features in the future I think I’ll just build on this. I always have the open source PDF library iTextSharp which I like quite a lot and now have SyncFusion PDF components and libraries in my arsenal, I have no intention to deal with adware-ridden, bloated applications with lots of security flaws.
