[Caml-list] Bitmap acquisition with Graphics module

[Caml-list] Bitmap acquisition with Graphics module

[Stalkern 2]

Hello to everybody.

Following a recent posting on the ocaml-beginners ML, I would like to ask you: 


how can one load an external bitmap picture using the Graphics library?


(See for instance the picture "jussieu" at 
http://caml.inria.fr/oreilly-book/html/book-ora048.html )

The book says: "A bitmap may be represented by either a color matrix (color 
array array) or a value of abstract type 1 image, which is declared in 
library Graphics. " but does not say anything about acquisition.

Any further hint about the image formats that can be used would be strongly 
appreciated.

Thank you
Ernesto Torresin

I had in mind ther ewas XPM format support in the `Graphics' library, but i
am afraid there is not. I have no direct answer to your question, i only now
you should install the `Camlimages' <http://pauillac.inria.fr/camlimages/> 
and check to the examples to see how to interface it with module Graphics,
and if you are interested, with lablgtk, both are possible.
