type t =
private (float, Bigarray.float64_elt, Bigarray.c_layout) Bigarray.Array1.tPixel <-> coordinate transformation
val get : Data_set.t -> tget t returns the geotransform array associated with t.
val get_origin : t -> float * floatget_origin t returns the (x, y) origin of rasters in t.
val get_pixel_size : t -> float * floatget_pixel_size t returns the (x, y) pixel size of the rasters in t.
val get_rotation : t -> float * floatget_rotation t returns the rotation of rasters in t.
val make :
origin:(float * float) ->
pixel_size:(float * float) ->
rotation:(float * float) ->
tmake ~origin ~pixel_size ~rotation creates a geotransform with the given specifications.
val set : Data_set.t -> t -> unitset t sets the geotransform array for t.
val apply : t -> x:float -> y:float -> float * floatapply t ~x ~y returns (x, y) translated by t, generally from native coordinates to pixel coordinates or from pixel coordinates to native coordinates.
