Hello all ;),
I would like to create text element - letter stimulus on 12mm height regardless of participants computer screen settings.
To do this I prepared some calibrations as follows:
I create reference line (RL) 500px long, I measured it with ruler and put measurement (M) result in mm into open ended element.
for my computer i have M=130mm
Next using <expressions> I divide M by RL so i have 130mm/500px=0,26mm/px
Then I divided my target height 12mm by 0,26mm/px so I have about 46px in my case
But there is some problem, if I measure my stimulus using ruler on computer screen I have 9mm not 12mm ;/
Can anyone help me?
Thanks in advance for any help.
I attach my script
