**Author** : Wanja Mössing, WWU Münster | [email protected] \n
*July 2017*
Parameters:
-----------
dispsize : tuple
two-item tuple width & height in px
Name : string
filename for the edf. Doesn't have to, but can, end on '.edf'
Maximum length is 8 (without '.edf').
Possible alphanumeric input: 'a-z', 'A-Z', '0-9', '-' & '_'
win : window object
You necessarily need to open a psychopy window first!
bits : integer
color-depth, defaults to 32
dummy : boolean
Run tracker in dummy mode?
colors : Tuple, Optional.
Tuple with two RGB triplets
Returns
-------
'el' the tracker object.
This can be passed to other functions,
although they can use pylink.getEYELINK()
to find it automatically.
