zbar-sharp, now bugfixed and pushed to github
Filed under: Computer,English,zbar-sharp by Jonas Finnemann Jensen at 08:02

I’ve long been wanting to play with Git, but have either missed the time or the reason… Anyway, as I discovered a minor bug in the zbar-sharp bindings I recently released… I figured this might just be the kind of project I could push to github, and either forget or bugfix depending on what mood I’m in when a bug is discovered… :)
So I’ve created a github repository for zbar-sharp, to which I’ve published a minor bugfix… I’ve also managed to publish the documentation there… it was a bit tricky, because GitHub only wants to serve HTML files if they’re in a special branch… Nevertheless I succeeded… And zbar-sharp can now be found here:

By the way did I mention, git is really nice… I just had a little fun making a bugfix branch and merging it…

ZBar bindings for C#
Filed under: Computer,English,zbar-sharp by Jonas Finnemann Jensen at 06:58

gtkzbar-sharp-exampleAs part of the food management system my group made this semester, we wrote bindings for ZBar and based on those a bar scanning widget for Gtk#. Anyway, I figured it might be useful somebody else, so I’ve been using a few days cleaning up the ZBar bindings, extracting the Gtk# widget from our UI-mess and writing a simple example of how to use it.

The result is bindings for a subset of ZBar and a Gtk# bar scanning widget. I don’t intend to maintain the source, but if you find any bugs etc. or wish to start a project for the bindings, please leave a comment…

The example application using the bar code scanning widget can be seen on to right. Note: this was a really lousy webcam :) . The check-mark appears when a bar code have been recognized and then fades away.

In Foodolini we used HAL to detect webcams as they were plugged, however, having heard that Ubuntu will be deprecating HAL, I didn’t care to clean up the source for this feature. If you interested it can be found in the source for Foodolini. And if anybody should happen to know how to detect webcams, distro independently, without HAL, please leave a comment…
