Here is the Javascript example code
.....
selRegion = Array(Array(1,1),Array(1,2),Array(2,2),Array(2,1))
Doc.Selection.Select(selRegion,1,0,0)
.....
Here is my interpretation in Python
.......
selregion = [(1,1),(1,2),(2,2),(2,1)]
print selregion
doc.Selection.Select(selregion,1,0,0)
......
Here is the error code generated
..........
F:\automation>test2.py
[(1, 1), (1, 2), (2, 2), (2, 1)]
Traceback (most recent call last):
File "F:\automation\test2.py", line 19, in ?
doc.Selection.Select(selregion,1,0,0)
File "<COMObject <unknown>>", line 3, in Select
pywintypes.com_error: (-2147352567, 'Exception occurred.', (0, 'Adobe
Photoshop', 'Illegal argument - argument 1\n- Only arrays with dimension 1
