I'm making a COM call that should return a two dimensional array, but
instead I get back a buffer that appears to only contain a single row
from the array.
Python 2.5.1 (r251:54863, Apr 18 2007, 08:51:08) [MSC v.1310 32 bit
(Intel)] on
win32

>>> import win32com.client
>>> mi=win32com.client.Dispatch("MIDLIBCom.MIDLib")
>>> cams=mi.OpenCameras("C:\Program Files\Micron Imaging\sensor_data")
>>> c=cams[0]
>>> c.startTransport()
>>> c.updateFrameSize(c.sensor.width, c.sensor.height, 8,0)
>>> f=c.grabFrame()
At this point f should be a 2048 by 1536 array of bytes, but instead...
>>> len(f)
2048
>>> type(f)
<type 'buffer'>
I know the COM library is returning the right data because if I do a
similar trick with IronPython...

>>> import MIDLIBCOMLib
>>> mi=MIDLIBCOMLib.MIDLibClass()
>>> cams=mi.OpenCameras("C:\Program Files\Micron Imaging\sensor_data")
>>> c=cams[0]
>>> c.startTransport()
>>> c.updateFrameSize(c.sensor.width, c.sensor.height, 8,0)
>>> f=c.grabFrame()
>>> len(f)
3145728
>>> type(f)
<type 'Array[Byte]'>
>>>
Its been squashed down to a 1 dimensional array, but at least all the
data is there.
