Hello @glv,
Thanks for your reply. So I’m guessing the only ways to save a frame that is currently displaying is to already have saved it at the end of draw(), or to save it at the start of the next call to draw()?
The only solution I can think of at the moment is to save every frame at the start of draw() using the same filename each time. Right-clicking the mouse could then change this filename, effectively preventing the first file from being overwritten.
