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 //x5
