The winners of the Nokia Imaging Wiki Competition 2013Q3 are super-stars of the Nokia Developer Community. This is the third article in a short series about our winners and their entries.
Yan Verdavaine was our third winner, for his article Memory-efficient Navigation in Very High Resolution Images on Windows Phone.
This article delivers two re-usable UI controls which enable fluid and memory-efficient zoom, pan and rotate inside very high resolution (or gigapixel) images, using the Nokia Imaging SDK. We were impressed with the results achieved both on high and low memory devices – irrespective of the image size. Not only is this a significant technical achievement, but the article is well written, and provides useful information that is not covered by the Nokia Imaging SDK documentation.
Yan also contributed Optimizing Imaging SDK use for rapidly changing filter parameters (used by the winning article) and valuable feedback about the SDK
He selflessly helped many other developers in this competition with advice about their articles (including some of our other winners) and, on the discussion boards, with guidance on how to best use the SDK.
Q. Tell us a little about yourself
I’m a software developer living in Rennes, and father of 3 small kids. For the last 8 years I’ve worked on many different projects:
- Physical Optronic simulation with Ray tracing and OpenGl.
- Qt 2D/3D GUI,
- Imagery computing,
- Video Server monitoring,
- Mobile development,
- Computational Photography (super resolution, plenotic design, …).
Development is now my hobby and in my spare time, I write articles on the Nokia Developer wiki, partake in board discussions and develop mobile applications for Windows Phone and other platforms. For several years, I was Moderator and Informatics book reviewer for the French developer community developpez.com “club des développeurs et IT Pro”
Q. How long have you been developing for Nokia platforms?
I didn’t get “properly” involved with Nokia development until Windows Phone and Nokia Lumia arrived. I found Windows phone really cool. After having attended a first training given by Nokia at Rennes, I’ve begun development Nokia Lumia.
Q. Have you developed many apps for Nokia devices?
I love investigating new technologies and I’ve developed a lot of samples to discover and understand different aspects of modern devices (NFC, Camera API, XNA/XAML mixte, Imaging SDK,). Sometimes, the sample is so good I create a proper application!
My first Nokia application was VAT Calculator, which I ported from a successful Android application. It was a simple VAT calculator app, but I discovered XAML, multi-language, and Dev Center publication with it. I’ve published two other very simple applications:
- Tile wars – Marmalade quick prototype
- Petits mots d’amour – developed for a competition and used to discover dynamic tiles.
My most important application is Monster Cam. I’ve develop it to discover the Camera API and 3D programming on Windows Phone. The first version was developed with XNA/XAML. The new version has been re-coded with DirectX, XAML and Imaging SDK. My articles for the competition are based on this experience.
Q. Any final thoughts?
Windows Phone is, for me, the most interesting mobile development. C# and XAML are cool but I would really like to see Qt running on it.
Imaging SDK is very amazing. I wish it success and prosperity ^^
