Struct Grid 

pub struct Grid {
    pub cell_width: Option<u32>,
    pub cell_height: Option<u32>,
}

Grid packing algorithm.

Every sprite occupies an identically sized cell. Sprites are placed left-to-right then top-to-bottom. Cell dimensions default to the maximum sprite width and height across all input sprites; they can be overridden via cell_width / cell_height for fixed-cell sprite sheets.

Sprites that are larger than the cell are sent to overflow without cropping. The atlas width is determined by the number of columns that fit within max_width; the height grows with each row added.

Fields

cell_width: Option<u32>

Fixed cell width in pixels. None → widest sprite.

cell_height: Option<u32>

Fixed cell height in pixels. None → tallest sprite.
