Example for the scanline debug mode on a Kobo Touch - bought it on Ebay, broken substrate, lower third of the display still operational. No idea what language it's set to.

With offset=105 the scanline is a tad too high: Click image for larger version

It might work but it's not optimal.

With offset=75 it's too low: Click image for larger version

With offset=95 it's okay: Click image for larger version

The scanline should cross the letters in as many places as possible.

Note I had to reboot the device between each offset change that should not be necessary, I'm still looking for that bug.
