I was looking at graphics tablets today. I''ve never used one. Among other interesting features, I notice they have pressure sensitivity. Am I to assume (MS Windows) the only way to read these input features of a graphics tablet is through DirectInput? If not, by what other means? And does anybody know if there is a ''standardized'' way of reading the input, or is it dependent on the particular brand and model. I have plenty of experience with C, algorithms, OpenGL, and the Windows API, but my DirectX knowledge is next to zero. If DirectInput is the only way, does anybody know of some good C (not C++) material to get something working for DirectInput?

Well, basically, graphics tablets were available long before Microsoft began thinking about DirectX, so you can''t expect DirectInput to be the one and only way to handle tablets - actually, I''d be impressed if DirectInput would handle these. Another hint is that none of the well-known painting programs such as Photoshop or Painter that supports graphics tablets relies on DirectX, even though I might be wrong.

Anyway, my guess is that it must rely on some standardized API, just like what TWAIN is for scanners and digital cameras. Or maybe the Windows API actually handles pressure-sensitivity directly through the common mouse routines... I''d say that taking a look into MSDN would be a wise thing to do
