    pub connectivity: Connectivity,
    pub nodata: Option<f64>,

Options controlling raster polygonization behavior.

Fields

connectivity: Connectivity

Pixel connectivity for connected component labeling. Default: Connectivity::Eight.

nodata: Option<f64>

Value treated as nodata (background). Pixels matching this value (within nodata_tolerance) receive label 0 and are excluded from the output polygons. Default: None (all values are data).

nodata_tolerance: f64

Tolerance for comparing pixel values against nodata. Default: 1e-10.

transform: Option<GeoTransform>

Optional GeoTransform for converting pixel coordinates to world coordinates. If None, output coordinates are in pixel space.

simplify_tolerance: f64

If > 0.0, apply Douglas-Peucker simplification to output polygons with this tolerance. Default: 0.0 (disabled).

min_area: f64

Minimum polygon area (in output coordinate units). Polygons smaller than this are dropped. Default: 0.0 (keep all).

boundary_method: BoundaryMethod

Boundary extraction method. Default: BoundaryMethod::PixelEdge.
