Hey people,
I m a very beginner and have a question. my code now generates a picture using basic elements like circles, lines etc.
Now i want to have a copy of the original picture within the original, for that i m using the get() function which works pretty well. now i have two questions
question 1
But i don t want that ugly white frame which comes from the background. how do i make that transparent?
question 2
I would also like to erase some of that picture i copy in. how do i do that?
there are probably answers to my problem out there, i have been looking for it for long and cannot find it!
to make sure i give all relevant information, i send all my code:
(it gets relevant at the very bottom
