Greetings,
According to Racket Docs:
Just set style-
'transparent – the canvas is automatically “erased” before an update using
it’s parent window’s background; the result is undefined if this flag is
combined with 'no-autoclear
Hopefully that helps.

is layered on Assembly. Or I may just be completely wrong in my perception
of that part.
In response to Professor Bloch:
How can those researched numbers be random? It can only LOOK random, but not

I am still going through lists of racket and java code to find
similarities...I have seen many similarities and started to implement these
similarities.
but i was asking in terms of how the looks. I find it a lot easier to work
from the GUI backwards.

Hey guys...those were all excellent answers and helped greatly.
However, it seems that Matthew Flatt's descriptions were a bit more
consistent with what i had in mind.
With this said, can anyone give me an example of the program implementing
what Matthew Flatt had described. It does not necessaril

an ***example.***] (the word between the two *** is green).?
Hopefully these questions weren't to verbose.

So in terms of garbage collection...the deletion of those arrays are the
only part.

I agree with that Robby, but the issue I see is once the image is loaded
once, in other words the image is seen on the frame/canvas at least once,
the next time it comes up on that same frame during the same run, it works
with minimal load time.
If someone has a bit of spare time, can he/she expla
, instead of loading images at the second you use them, can you
load it at the beginning of running a program.
