Alg (gdal.Gdal.Alg)

val proximity : ?⁠options:string list ‑> src:(_, _) Band.t ‑> test:(_, _) Band.t ‑> unit

proximity ?options ~src ~test computes the pixel-by-pixel proximity between src and test.

val fill_nodata : ?⁠options:string list ‑> target:(_, _) Band.t ‑> mask:(_, _) Band.t ‑> float ‑> int ‑> unit

fill_nodata ?options ~target ~mask distance iterations will fill in target's missing data pixels. See GDAL's GDALFillNoData documentation for an explanation of the function parameters.

val generate_contours : ?⁠no_data:float ‑> ?⁠id:int ‑> ?⁠elevation:int ‑> ('v, 'e) Band.t ‑> Layer.t ‑> [ `fixed of float list | `interval of float * float ] ‑> unit

generate_contours ?no_data ?id ?elevation band layer contours will create contours from band, adding them to layer.

Parameter no_data: will be used as the "no data" value if specified.
Parameter id: specifies a field where an identifier for each contour written to layer.
Parameter elevation: specifies a field where the elevation value for each contour is written.
Parameter band: is the field to generate contours from.
Parameter layer: is the layer where contour geometries will be written to.
Parameter contours: specifies the contours to create. `fixed l will create contours for each value in l. `interval (start, step) will create intervals starting with start and step intervals past that.

val rasterize_geometries : ?⁠transform:'a Transform.t ‑> ?⁠options:string list ‑> Data_set.t ‑> int list ‑> (Geometry.t * float list) list ‑> unit

rasterize_geometries ?transform ?options ds bands geometries burn will will rasterize geometries onto ds.

Parameter ds: is the data set where output is written.
Parameter bands: specifies the list of bands to update.
Parameter geometries: is the list of geometries to burn in and the values to burn, one per entry in bands.
Parameter transform: specifies the transformation to pixel/line coordinates. Not required if ds and geometries use the same coordinates.
Parameter options: specifies rasterization options. See the documentation for GDALRasterizeGeometries for available options. Defaults to [].
Raises Invalid_argument: if the length of the burn value list(s) do not match the length of the band list.

val rasterize_layers : ?⁠transform:'a Transform.t ‑> ?⁠options:string list ‑> Data_set.t ‑> int list ‑> (Layer.t * float list) list ‑> unit

rasterize_layers ?transform ?options ds bands layers burn will will rasterize layers onto ds.

Parameter ds: is the data set where output is written.
Parameter bands: specifies the list of bands to update.
Parameter layers: is the list of layers to burn in and the values to burn, one per entry in bands.
Parameter transform: specifies the transformation to pixel/line coordinates. Not required if ds and layers use the same coordinates.
Parameter options: specifies rasterization options. See the documentation for GDALRasterizeLayers for available options. Defaults to [].
Raises Invalid_argument: if the length of the burn value list(s) do not match the length of the band list.
