To: caml-list
I'm working on an OCaml application which I'd like
to do the following: load an existing postscript
file from disk, launch a window in which the
document is displayed, and allow the user to select a
rectangle on a page of the document using the mouse
(and of course have access to the bounds of the rectangle
within the application). What libraries/tools are
available to do such a thing?
Thanks

This is not handy at all, since interfacing with ghostscript is painful, but I do not know any better solution. ------------------- To unsubscribe, mail caml-list-request@inria.fr Archives: http://caml.inria.fr Bug reports: http://caml.inria.fr/bin/caml-bugs FAQ: http://caml.inria.fr/FAQ/ Beginner's list: http://groups.yahoo.com/group/ocaml_beginners ^ permalink raw reply [flat|nested] 11+ messages in thread

Another alternative might be to try to interface with the ghostscript interpreter API: http://www.cs.wisc.edu/~ghost/doc/cvs/API.htm (or http://www.cs.wisc.edu/~ghost/doc/gnu/7.05/API.htm if you want it unter the GPL).

Maybe you can also use gdkpixbuf interface of LablGtk instead of Camlimages, but I am not really sure.

BTW, have you tested camlimages with the (alpha) lablgtk2 ? And is it still possible to build camlimages with libpng 2 ?

Well, the thing is, in debian, gnome 1 packages are linked against libpng2, and gnome2 (including gtk2) packages are linked against libpng3 (well, libpng12-0 actually). And you cannot have the devel environment for both libpngs installed at the same time. Stefano builds his camlimages with libpng3 though, and it uses the lablgtk packages. In turn, lablgtk depends on libgtkxmhtml-dev, which depends on libpng2. I thought that the correct way would be to have two camlimages, one which uses lablgtk and libpng2, and the other which uses lablgtk2 and libpng3. I am not sure, but mixing both libpngs in a same executable may cause problems, maybe ...
