I'm using ctypes to have a dll fill a buffer with 16 bit data. I then
want to convert this data to a numpy array. The code snippet below
converts the data from 16 bit to 32 bit, but two 16 bit numbers are
concatenated to make a 32 bit number and half the array is zero.
Buffer = (c_short * byteSize)()
self.cam.Qframe.pBuffer = cast(pointer(Buffer), c_void_p)
perr = self.cam.GrabFrame()
image1 = np.frombuffer(Buffer, int)
xdim = self.cam.Qframe.width
ydim = self.cam.Qframe.height
image2 = image1.reshape(xdim, ydim)
image2 looks like
[[6291555 6357091 6160481 ..., 6488160 6226020 6553697]
[6488163 6422625 6684770 ..., 6422624 6553697 6553696]
[6488160 6357091 6226018 ..., 6815842 6422627 6553696]
...,
[ 0 0 0 ..., 0 0 0]
[ 0 0 0 ..., 0 0 0]
[ 0 0 0 ..., 0 0 0]]
How do convert 16 bit data to 32 bit data?
Thanks
