Save_Image Error

[dpalo325]

Hi,

I'm currently attempting to run the demo.py, but I come across an error when attempting to save the file.

Specifically it prints the following error- “File "C:\Users\palod\Desktop\pyicic\IC_Camera.py", line 479, in save_image c_char_p(filename), TypeError: bytes or integer address expected instead of str instance”

I attempted to fix this by using the c_wchar_p instead, but this returns another error. I was wondering if you could offer any insight as to how I could possible alter this code/ what I need to do to get this demo to work properly. I am using a monochrome GigE camera, python 3, and I have not altered your code except for what is necessary. I am running this on windows 10, and I thought I should note that I do not currently have any light entering the camera, so it is receiving zero signal.

Thank you

Off the top of my head I'd guess this has something to do with Python 3 (I've only used this library with Python 2, which treats strings differently). You could try something like filename = b"your_filename" to ensure filename is a bytes array.

Thank you for the fast response. Ok I will give that a try and if not I will attempt it on Python 2.

@dpalo325 Hi , I am getting the same error. Did you happen to resolve this or did you end up using it with Python 2.xx ?

Sorry, Python 3 wasn't tested with this lib. I don't intend to update this code or debug as I no longer use these cameras.

I've just inherited an IC camera and trying to get it to work using spyder python 3.

The solution I found to this problem is to append the file name with .encode('utf-8').

So for the example on in the basic usage example in readme.md, change:

cam.save_image(''.join(['image-', str(i),'.jpg']), 1)

to

cam.save_image(''.join(['image-', str(i),'.jpg']).encode('utf-8'), 1)

and don't forget to add parentheses in the print commands.
