Re: [Matplotlib-users] Animation with an image in the backgroud

[Benjamin R. <ben...@ou...>]

I should first note that the way to do animations in matplotlib will
probably be improved soon, the current methods should still be valid.

Ok, the way how I understand how blitting works is that a copy of the static
background is made before any of the "sprites" are drawn.  That static
background is then redrawn at each frame to avoid having to do a complete
re-render of it.

So, if you can display a particular image to a plot before calling
copy_from_bbox(), but after the canvas.draw() call, then the animation
should work as you would like with blitting, and you won't need to repeat
the function call to plot the background in the animation.

Note, I have not tried this, so please let us know how this works for you.
