]> Hi, I'm writing a simple texture loader class so that I can load up images using camlimages, convert them to a format suitable for opengl, then store them under some name in a hash table. So far I've got it working for rgb24 format images, but ideally I want to use both 24bit rgb pixels and 32bit rgba pixels. The problem is deciding which function to call depending on the image type. Before I go on, is this an appropriate place to ask about CamlImages? Also I am new to OCaml, and this is one of the few things I've attempted of any complexity. This is the class as it stands. class texture_loader = object(self) val mutable texts = Hashtbl.create 5; method load (filename : string) (tex_id : string) = try let x = Hashtbl.find texts tex_id in raise (Id_exists tex_id) with Not_found -> let img = OImage.load filename [] in let img = OImage.rgb24 img in Hashtbl.add texts tex_id (rgb_to_gl img); () end;; Assuming I have functions "rgb_to_gl" and "rgba_to_gl", how can I tell which format the image is so the correct function can be called. Something like this is what sprang to mind let img = match <image_format> with <rgb> -> OImage.rgb24 img | <rgba> -> OImage.rgba24 img in ... The problem is what should the things between the angled brackets be?
