Crate sprite_slicer 

sprite-slicer provides file-oriented helpers for common 2D sprite-sheet workflows.

It supports:

• slicing a fixed sprite grid into frames
• detecting sprites from a transparent sheet
• grouping frames into actions
• exporting GIF previews
• removing a connected background color
• normalizing frames onto a shared canvas
