Warp Operations

type 'a t

val create : 'a Options.t -> 'a t

create o creates a warp operation value based on the given options.

val warp : ?offset:(int * int) -> ?size:(int * int) -> _ Options.t -> unit

val warp_multi : 
  ?offset:(int * int) ->
  ?size:(int * int) ->
  _ Options.t ->
  unit

Convenience functions for carrying out a warping operation. They use the chunk_and_warp_* functions internally.

val chunk_and_warp_image : 
  _ t ->
  offset:(int * int) ->
  size:(int * int) ->
  unit

val chunk_and_warp_multi : 
  _ t ->
  offset:(int * int) ->
  size:(int * int) ->
  unit

chunk_and_warp_* t ~offset ~size carry out the warp operation t by chopping up the processing into chunks which are small enough to fit in the memory limits specified in the Options.t value used to create t.

parameter offset
specifies the (x, y) pixel offset to target in the destination data source.

parameter size
specifies the (x, y) size in pixels of the region to warp to in the destination data source.

val warp_region : 
  _ t ->
  dst_offset:(int * int) ->
  dst_size:(int * int) ->
  src_offset:(int * int) ->
  src_size:(int * int) ->
  unit

warp_region op ~dst_offset ~dst_size ~src_offset ~src_size warps the defined region according to op.

val warp_region_to_buffer : 
  ?buffer:('e, 'v, Stdlib.Bigarray.c_layout) Stdlib.Bigarray.Array2.t ->
  _ t ->
  ('e, 'v) Band.Data.t ->
  dst_offset:(int * int) ->
  dst_size:(int * int) ->
  src_offset:(int * int) ->
  src_size:(int * int) ->
  ('e, 'v, Stdlib.Bigarray.c_layout) Stdlib.Bigarray.Array2.t

warp_region_to_buffer is like warp_region except that it writes the result to buffer.

parameter buffer
may be used to provide a pre-allocated output buffer.
