Empty image

How I can create and show an empty image in my wx program (python):

I try with this:

        bmp=wxImage(10,10)
        self.image=wxStaticBitmap(page1, -1,bmp)

but it is make an error:

init__
    self.this = apply(imagec.new_wxImage,_args,_kwargs)
TypeError: String or Unicode type required
Exception exceptions.AttributeError: "wxImage instance has no attribute 'thisown
'" in ignored
13:44:05: Debug: e:\projects\wx\src\msw\app.cpp(439): 'UnregisterClass(canvas)'
failed with error 0x00000584 (az osztßly mÚg rendelkezik nyitott ablakokkal.).

This hungarian section in english: the class is have an opened window.

What I do wrong, how I do in good way ?

( I want to make an my own drawed diagram and show in the image)

Thx:
