An animation flower made with MyPaint branch of Pencil2D, I first done a rough, to test with my code, after code was in place for frame-by-frame animation to mesh, I polished the animation a bit. I noticed also some errors from the first batch I was able to correct. Still need to do some changes because the png spritesheet is too big for a 128×128pixels of 8 frames animation (I reduced by 2 the drawing, as generally done in comics.) it take 190~200KB, that means that 5 objects like this is already 1MB, cumulating quickly to tens of MB of pictures. I loose lot of place around the flower, but this should be removed by png compression (will still take graphics RAM/bandwidth after uncompression in memory), So I think about unlink the stem from the flower.
The contrast isn’t really visible after reduced in 128×128, so as in animation, color contrast must be boosted to have a visible effect.
