HOW PHOTOSHOP GET THE BRUSH PRESSURE...

HELLO!!



I saw some people using a WiiRemote to DIY a touch screen.and of course the IR PEN have no pressure-sensitive.



I wonder ,even if i made a force-sensitive-device ,then connect it to USB host. but HOW PHOTOSHOP KNOW THE PRESSURE SIGNAL??what i need to do inside the driver code?



is that a sdk or something to change a pressure signal FROM device TO photoshop??



THANKS!

It is a driver of sorts. The standard way for applications to communicate with pointing devices is through an API called Wintab. If you look around the web you will find it easily. It comes as a DLL, a header and a few lib files. Note, it dosen't belong to Microsoft. I think the DLL is vendor/hardware specific.



I don't know enough to tell you exactly what the hardware is actually sending. I know its pretty slow though.
