How are you unsuccessful? What is going wrong? What exactly do you want to draw? Can you show us the code you tried?

We can't help if you don't give as many details as possible.

Then your code is not properly indented. Post the code you're using.

Please use code tags. Press the "Go Advanced" button under the quick reply field, and in the editor, press the button with the # symbol on it. Copy your code between the tags the editor inserts. That will preserve code indentation. Otherwise, the way you posted it, nothing is indented, which makes it impossible to spot the problem.

I don't see any indentation problems... At what line does the error say the problem occurs? Please post the exact error message.

bgimg=Image.open('e\\data\\python\\imgname.jpg")
Indentation error: unindented does not match any outer indentation level
