I previously posted about a little utility that I was working on that shows off the pressure levels detected by all most active digitizer tablets. (Rob Bushway pointed out in a comment that not all active digitzers present pressure information to the OS).
Well - I've not had much time do more work on the util but I have decided to release it as is for people to have a play with.
It was written against version 6.0 of the Microsoft.Ink assembly - so in theory it will require Vista. I don't have any XP tablets to test it against but I would not expect it to work.
Basically you run it up and as you press down in the window a circle dynamically sizes around the tip of the pen - the radius is relative to the pressure level being recorded at the time. As pressure decreases I have to refresh the drawing area so you can see the new circle, which causes some flickering, but you can still see what is going on. If you run it on a touch screen device or on a device without an active digitizer it will work, but it is not that interesting because these devices always return the same value for pressure (if at all).
Download the tool here - it is really just a toy with no real use, but any feedback is appreciated. Guaranteed to provide minutes of entertainment or your money back.
