Hi Michael, The values are related to the display device resolution. Each Protocol has the EFI_ABSOLUTE_POINTER_MODE defined and it has the value of the actual screen hardware resolution ( not the current display resolution).
The touched values are based screen hardware resolution. Thanks, Ramesh -----Original Message----- From: edk2-devel [mailto:[email protected]] On Behalf Of Michael Zimmermann Sent: 21 August 2017 22:12 To: edk2-devel-01 Subject: [edk2] meaning of EFI_ABSOLUTE_POINTER_PROTOCOL axis values Do the axis-values returned by this protocol need to have any relation to the device's screen so I can reliably calculate which pixel was touched?(at least with the rule of three). If not every application using the touchscreen would have to provide it's own calibration tool and store the results in a config.
