Struct TilePlacement 

pub struct TilePlacement {
    pub index: usize,
    pub count: usize,
    pub origin: (f32, f32),
    pub crop_size: (f32, f32),
    pub letterbox: Option<[f32; 4]>,
    pub frame_dims: (f32, f32),
}

One tile’s placement within a frame grid.

Produced by edgefirst_image::ImageProcessor::plan_tiles and consumed by edgefirst_decoder::tiling to lift per-tile detections back to full-frame coordinates. It lives here because it is the contract between those two crates: it was previously defined in decoder and re-exported by image, so the producer imported its own output type from its consumer.

Fields

index: usize

Tile index within the frame grid, 0..count.

count: usize

Total tiles for this frame (the streaming fan-in fence).

origin: (f32, f32)

Native crop origin (ox, oy) in full-frame pixels.

crop_size: (f32, f32)

Native crop size (cw, ch) in full-frame pixels. Equals the tile size for the full-size tiles the EvenDist grid produces.

letterbox: Option<[f32; 4]>

Normalized letterbox content bounds [lx0, ly0, lx1, ly1] on the model input, or None when the crop was stretched to fill it (the hot path).

frame_dims: (f32, f32)

Full-frame dimensions (frame_w, frame_h) in pixels.
