Subject: [Caml-list] Wich solution for a fast powerfull drawing area ?
Date: Tue, 9 Jul 2002 22:40:51 +0200 [thread overview]
Message-ID: <20020709224051.A1618@libertysurf.fr> (raw)
Hello,
I'm looking at ocaml as the language to make ultrasonic programs.
The difficult part for me is the scientific imaging.
I will have to show waveforms (typically 1024 points long) and colormaps
(1024 * 100 * 256 levels of color for example) at comfortable
speed (I mean more than 20 Hz).
I tried to use lablgtk and camlimage starting from the examples, but
didn't achieve to get a area in wich I can draw all what I want...
Starting from the lablgtk drawing.ml example, I was not able to
chose/create RGB colors. My feeling is that there is something to do
to have the right colormap or extend it ?
I would appreciate any suggestion to progress.
I would need:
* to be able to draw and change the colors,
* a very nice point would be to have transparency, in order to be able
to implement layers in graphical widgets (composite widgets in ocaml,
or gtk widget in C + binding ?)
* the ability to manipulate some decorations on the graphic with the
mouse (event handling)
* and certainly a lot more...
Well, all this is not so far from the canvas widget (Tk, Gnome).
Thanks in advance
