Enum TileShape 

pub enum TileShape {
    Strip {
        rows: u32,
    },
    Square {
        size: u32,
    },
}

The shape tiles take through a segment of the graph.

Variants

Strip

Full-width strips of at most rows rows.

Matches how codecs produce and consume pixels, so a sequential segment moves data with no repacking.

Fields

rows: u32

Maximum rows per strip; the final strip may be shorter.

Square

Square tiles of at most size × size pixels.

Used where a spatial op needs a neighbourhood, so that border pixels are recomputed for four edges rather than for the full image width.

Fields

size: u32

Maximum edge length; edge tiles may be smaller.

Implementations

impl TileShape

pub const DEFAULT_STRIP_ROWS: u32 = 64

The default strip height, in rows.

pub const DEFAULT_SQUARE_SIZE: u32 = 128

The default square tile edge, in pixels (ADR-0003).

pub fn tiles(self, region: Region) -> Vec<Region>

Split region into tiles of this shape, in production order.

Order is top-to-bottom, then left-to-right, so a sink consuming the result sees rows in order wherever the shape allows.
