My stim are letters (X or O) that appears at 10° of visual angle. Coded by the following line :
vis = visual.TextStim(win, text= mytext, pos = (side*10,0.0), color=[-1.000,-1.000,-1.000], units = 'deg', height= h)
So I choose a certain height h (for example h = 4).
What is the unit of "height" and How can we know the size of the letter in pixel ?
Thank you for your answer,
and Happy new year !
