Module Rgba32

RGBA 32 bit depth image format

type elt = Color.rgba
type rawimage
type t = {
  1. width : int;
  2. height : int;
  3. rawimage : rawimage;
  4. mutable infos : Info.info list;
}
val resize : (float -> unit) option -> t -> int -> int -> t

resize progress t w h creates a resized image of t with size wxh. You can specify a progress meter function progress, which takes a float from 0 to 1.0.
