Hope this is helpful. I have been wanting to revise making videos for a while.

One of the most powerful 2D drawing command IMHO, thanks to its speed.

Not at all!

What I wonder since I saw the blt related commands in the catalog is if it possible to define the graphics plane displayed.
Could not find something to achieve that but being able to swap the planes (synced to the tft refresh) would offer tools for flicker-free buffering.

Can you do so or is g0 always the visible plane?

[Kevin Ouellet]

You cannot switch directly, but you can, for example, store your graphics and drawings in g1, g2 or higher, then once you are finished drawing everything, you just copy the result into g0. It pretty much eliminates all the flicker.
