Automatic Sprite Pivot Alignment
Detect the visible character area across animation frames and align them to a shared pivot and canvas size.
For walk, idle, and attack animations, Centro inferior is usually the most stable choice. Bounds center or alpha-weighted centroid may work better for airborne objects and effects.
How it works
- Find the bounds of pixels whose alpha exceeds the selected threshold.
- Calculate each frame’s pivot using the selected mode.
- Calculate a shared canvas that does not crop any frame.
- Reposition every frame around the computed shared pivot.
- Select only the frames you need and save them together as a ZIP.
Modo de alineación
Centro inferior usa el punto más bajo del personaje y el centro horizontal, por lo que es adecuado para animaciones sobre el suelo. Centro del área opaca funciona bien para iconos y objetos giratorios, mientras que centro ponderado por alfa es útil para efectos semitransparentes.
Limitations
If shadows, weapons, capes, or other parts extend to the lowest pixels, the detected foot position may shift. Animations with large pose changes may still need manual adjustment after checking the automatic result.
