Module `Gdal.Geo_transform`Source

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

Pixel <-> coordinate transformation

Sourceval get : Data_set.t -> t

get t returns the geotransform array associated with t.

Sourceval get_origin : t -> float * float

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

Sourceval get_pixel_size : t -> float * float

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

Sourceval get_rotation : t -> float * float

get_rotation t returns the rotation of rasters in t.

Source

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.

Sourceval set : Data_set.t -> t -> unit

set t sets the geotransform array for t.

Sourceval 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.

Sourceval invert : t -> t

invert t inverts the geotransform t.
