print("Opening File: " + input_file)
datatype = numpy.dtype('>i2') #16-bit big-endian data
e1=1201 # Height
e2=1201 # Width
size=e1*e2*datatype.itemsize
shape=(e1, e2)
#data = np.zeros(shape)
data = numpy.fromfile(input_file, datatype, size)
data = data.reshape(shape)
fig1 = pylab.figure(1)
imgplot = matplotlib.pyplot.imshow(data)
imgplot.set_cmap('gray')
imgplot.set_clim(3500,6600)
imgplot.set_interpolation('nearest') # 'bilinear' , 'bicubic', 'nearest'
matplotlib.pyplot.colorbar()
