Error of zGetSurfaceData #87

Closed tnakaicode closed 5 years ago

tnakaicode commented 5 years ago

I tried to run following code and got error.

ValueError: could not convert string to float: 'BAD COMMAND'

I want to know how to avoid this error. I use Python 3.6 and Zemax 150624.

import numpy as np
import matplotlib.pyplot as plt
import pyzdde.zdde as pyz
import os

ln = pyz.createLink()
print("Hello Zemax version: ", ln.zGetVersion())
ln.zSetSurfaceData (0, 1, "0.0")
ln.zSetSurfaceData (0, 3, 0.0)
ln.zSetSurfaceData (1, 3, 0.0)
ln.zSetSurfaceData (2, 3, 0.0)
print(ln.zGetSurfaceParameter (3, 3))
ln.zSetSurfaceData (3, 3, 0.0)

ln.close()

The function zSetSurfaceData expects integers as input but you have provided a float ln.zSetSurfaceData (0, 1, "0.0")
