[python-win32] Python COM and Photoshop

[Sam The Cat]

One more thought -- I have tried both Early and Late binding COM calls and I 
get the same error message either way.



>I thought I'd try this again -- still no progress on my debugging.  From 
>using Visual Basic it seems that the interface is expecting an array of 
>type varint where each element of the array is another array.  The inner 
>arrays are two elements long (an x and y data point)
>
> I have also tried using the array module but I still get the same 
> errors --  basically anything that I try in Python results in a error 
> indicating that only a 1-dimensional arrays are supported -- which seems 
> weird since the vbasic code is not making a single dimensional array.
>
> Any thoughts are appreciated
