Adjusting this virtual ruler to actual size
The diagonal screen is 15.6"(inches) of my laptop computer, resolution is 1366x768 pixels.
I google the PPI reference and found 100 PPI to my screen,
after i measure the size of virtual ruler by a actual ruler,
i found the markings are not very accurate at 30cm,
so i set the default pixels per inch(PPI) is 100.7 for myself.
