问题
I am trying to write a python script on Windows 7 to interact with my Wacom Bamboo Pen tablet. Wacom recommends using the WinTab API, and it works fine, but not for my application. I don't want the Wacom tablet to act as a pointing device (as in, it should not move the cursor). All I want is raw x, y data from the device.
What is the best way to implement this? Do I have to write a different driver for the tablet to allow this? Or can I modify the existing Wacom driver to not affect the system cursor.
回答1:
I think, in wintab you can get the raw coordinates. At least in Python wrapper for wintab you can access them:
cgkit.wintab.Packet.x
In absolute mode, contains the scaled cursor location along the x axis. In relative mode, contains the scaled change in cursor position.
cgkit.wintab.Packet.y
In absolute mode, contains the scaled cursor location along the y axis. In relative mode, contains the scaled change in cursor position.
I'm investigating for myself if there is an cross-platform api for tablets, but if you need windows-only solution that should work.
