-m 5 "Animation"
Animation frames are 6 character (or 48px) wide. Upload an animation of
N frames as one image N*48 pixels wide, 11 pixels high.
Frames run from left to right and repeat endless.
Speeds [1..8] result in ca. [1.2 1.3 2.0 2.4 2.8 4.5 7.5 15] fps.
Example of a slowly beating heart:
sudo %s -s1 -m5 " :heart2: :HEART2:"
-m 9 "Smooth"
-m 10 "Rotate"
These modes are mentioned in the BMP Badge software.
Text is shown static, or sometimes (longer texts?) not shown at all.
One significant difference is: The text of the first message stays visible after
upload, even if the USB cable remains connected.
(No "rotation" or "smoothing"(?) effect can be expected, though)
