Hello,

I'm just developing application for medical tests with graphic tablet. My tablet works just fine (I receive events, and handle it). But I'm struggle with two dilemmas:

1. Is there any way to measure distance traveled by pen on tablet during drawing? With mouse I can do this quite easily using screen resolution information and some math. But with tablet I don't have information about it's resolution and real number on pixels that a pen traveled (informations from

hiResGlobalPos are after some transformations).

2. I need my event receive in equal time interval, say 10 miliseconds, this is because I perform FFT on it. Does anyone has some simple idea for that?

I will be very thankful if someone help me with this

best regards
Paweł
