wxpython - How do I use wx.GIFHandler's SaveAnimation method?

Question

I have a python program that produces a sequence of wx.Image objects, and I would like to make an animated GIF out of them. I am trying to see if I can use wx.GIFHandler in wxPython to do this, but I can't figure out what to pass as the images argument. I was hoping I can avoid importing PIL or cv2, since I have already imported wx, and it seems to have built-in functionality to do this.

Here's the API reference:

SaveAnimation(self, images, stream, verbose=True, delayMilliSecs=1000)?

    Save the animated gif.

    Parameters

            images (ImageArray) – The image array object which is to be affected by this operation.

            stream (wx.OutputStream) – Opened output stream for writing the data.

            verbose (bool) – If set to True, errors reported by the image handler will produce LogMessages

            delayMilliSecs (int) – How long, in milliseconds, to wait between each frame.

    Return type
        bool

    Returns
        True if the operation succeeded, False otherwise.

According to the API reference for wx.GIFHandler SaveAnimation, the images argument takes an ImageArray, but the only reference I can find to it is in the C++ code here, which appears to be a reference to a C++ array of C++ wx.Image objects.

I've tried passing a python list, a wx.ImageList, and a numpy.array -- none of them seem to work.

Thanks in advance for any help I can get!

TL;DR: How do I create an ImageArray object to pass to SaveAnimation?
