ABS_MT_TOUCH_MAJOR
Top / ABS_MT_TOUCH_MAJOR
The diameter of the inner region
The length of the major axis of the contact. The length should be given in surface units. If the surface has an X times Y resolution, the largest possible value of ABS_MT_TOUCH_MAJOR is sqrt(X^2 + Y^2), the diagonal.
メモ
- Unfortunately for Eclair and Froyo the driver must declare that it supports ABS_MT_TOUCH_MAJOR.
