Explication technique
Pointer Events expose pointerType, pressure, tiltX, tiltY, and coordinates. Pen pressure is normalized from 0 to 1 and may be simulated by some browsers when the hardware does not report it.
A browser cannot read the pen’s internal calibration or button layout. Hover, barrel buttons, and eraser detection depend on the operating system and browser implementation.
Dépannage
Pressure stays the same
Your device or browser may not expose pressure. Check whether the pen supports pressure in another drawing app.
Pen is treated as a mouse
Some browsers or remote-desktop sessions lose pen metadata. Try a local browser session.
No tilt values
Tilt requires hardware and browser support and is not available on all tablets.
Erase mode is missing
Eraser detection depends on the pen and operating system. Use the eraser mode button if pressure is not exposed.
