When using a 16 bit pixel format and supplying
getNextNumPyFrameanp.zeros((2048, 2048), dtype=np.uint16)frame buffer, pixelink thinks that the array is too small. Supplyingnp.zeros((2048,2048*2), dtype=np.uint8)like used by the examples works, but makes less sense to me.I thus added the array element bytesize to the buffer size calculation.
I'm aware that afterwards I've to call numpy's
byteswapfunction for big/little endian conversion.
