Hi,
I'm trying to load an image into Zen Blue using the python COM interface with this code:
Code: Select all
import win32com.client
Zen = win32com.client.GetActiveObject("Zeiss.Micro.Scripting.ZenWrapperLM")
Zen.Application.LoadImage('C:/test.tiff')
and get the following error:
Code: Select all
---------------------------------------------------------------------------
TypeError Traceback (most recent call last)
<ipython-input-32-7115728bee1f> in <module>
1 import win32com.client
2 Zen = win32com.client.GetActiveObject("Zeiss.Micro.Scripting.ZenWrapperLM")
----> 3 Zen.Application.LoadImage('C:/test.tiff')
TypeError: LoadImage() takes 1 positional argument but 2 were given
Can you provide me with example code how to load an image into Zen using the COM interface?
Thanks,
Johannes

Hello jelferich,
first of all the error message is a bit misleading.
So
LoadImage() takes 1 positional argument but 2 were given
should be
LoadImage() takes 0 positional argument but 1 is given
Python has an internal 'this' as a parameter, which is also counted.
As already said in this forum, COM has no 'Function Overloading'.
To overcome this problem, COM uses
underscore plus a number added to the function e.g. LoadImage_2
So in your case
im = Zen.Application.LoadImage_2('C:\\test.tiff')
should work

Hi,
I want to load a czi file through Matlab com interface, can you provide a demo script to do this? My Zen version is black version 2012. Thank you very much.

Sorry for the late reply, but this is a forum for Zen blue only.
Therefore I had to organize some description:
COM interface (Zen Black)
The full range of ZEN VBA commands is also available via COM, by connecting a client program to a running ZEN system. There are two COM-automation objects available, for the Lsm5Vba interface and for the VBA-GUI interface. The COM object Lsm5Vba is called "Lsm5Vba.Application", and the one for the VBA-GUI interface is called "Zeiss.Micro.AIM.ApplicationInterface".
For example to connect a MATLAB session to ZEN, start ZEN first, start MATLAB, and then type
ZENVBA = actxGetRunningServer('Lsm5Vba.Application')
ZEN = actxGetRunningServer('Zeiss.Micro.AIM.ApplicationInterface.ApplicationInterface')
To start a scan, two commands are now available
ZENVBA.Lsm5.StartScan
ZEN.GUI.Acquisition.Snap.Execute
It sounds to me that you need the Zen black VBA module to work with the COM-interface.
Please contact your local ZEISS sales or support people for further information.

I am not sure how to resolve it. Can someone help me with fixing this.

Did you manage to get it running?
Most probably the COM interface has not been registered via 'regasm'.

Try this:
Code: Select all
import win32com.client
try:
Zen = win32com.client.GetActiveObject("Zeiss.Micro.Scripting.ZenWrapperLM")
except Exception as e:
print(f"An error occurred: {e}")
Remember to replace the placeholder
"Zeiss.Micro.Scripting.ZenWrapperLM" with the actual Class ID if it's different.
