Module Gdal.Geo_transform

type t = private (float, Bigarray.float64_elt, Bigarray.c_layout) Bigarray.Array1.t

Pixel <-> coordinate transformation

val get : Data_set.t ‑> t

get t returns the geotransform array associated with t.

val get_origin : t ‑> float * float

get_origin t returns the (x, y) origin of rasters in t.

val get_pixel_size : t ‑> float * float

get_pixel_size t returns the (x, y) pixel size of the rasters in t.

val get_rotation : t ‑> float * float

get_rotation t returns the rotation of rasters in t.

val make : origin:(float * float) ‑> pixel_size:(float * float) ‑> rotation:(float * float) ‑> t

make ~origin ~pixel_size ~rotation creates a geotransform with the given specifications.

val set : Data_set.t ‑> t ‑> unit

set t sets the geotransform array for t.

val apply : t ‑> x:float ‑> y:float ‑> float * float

apply t ~x ~y returns (x, y) translated by t, generally from native coordinates to pixel coordinates or from pixel coordinates to native coordinates.

val invert : t ‑> t

invert t inverts the geotransform t.
