Tablet pressure sensitivity test?
I'm wondering if there is a way of testing the pens sensitivity to pressure in real-time. I can hear it now. "Draw a line dummy."

To be more specific, does anyone know of a tool that can test number of levels of pressure sensitivity that a pen is capable of. I thought for sure I would find some downloadable software somewhere but no luck.

I'm using a Bamboo Pen and interested in how to verify it is in good working condition and reaching it's whopping 512 levels of sensitivity and also whether I'm pressing harder then I need to.

On Linux you can do it using "xinput"
Code:
xinput --list "Wacom Bamboo" | grep -B 1 -A 5 "Pressure"
                Detail for Valuator 2:
                  Label: Abs Pressure
                  Range: 0.000000 - 511.000000
                  Resolution: 1 units/m
                  Mode: absolute
                  Current value: 454.000000

xinput --query-state "Wacom Bamboo" | grep valuator
        valuator[0]=4637
        valuator[1]=6917
        valuator[2]=61
        valuator[3]=0
        valuator[4]=0
        valuator[5]=0

(values above from my Bamboo tablet (Wacom MTE-450)

The scale seems non-linear, levels below 100 are really in the "feather touch" category.

In case anyone else is curious....

Finally found what I was looking for in one of the most obvious of places.

Wacom has a software developer support website with a browser plug-in that did the job.

Still wonder how that browser plugin works if you haven't got a proper driver installed.
