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

I once wrote a program which only displayed postscript, and I used
ghostscript. That is, my program calls Unix.open_process_out, with the
expected arguments. This is not handy at all, since interfacing with
ghostscript is painful, but I do not know any better solution.

One possibility is a combination of LablGtk and Camlimages
LablGtk provides a GUI and Camlimages is for image file manipulation.
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 ?

Nope. Do you need it ?

Yes, I still use libpng2-dev.

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 ...

Notice that i believe advi has some code doing just that, since it is
able to display the postscript includeded by a .dvi file.

gv student_seminar.ps & sleep 3; import output.png
Wait until the mouse pointer changes shape before selecting the rectangle
"import" is part of imagemagick package (there is also libmagick you might
like)

It is more right, IMHO.

But it doesn't do anything the OP wanted, does it? He wanted to display PS
interactively and select rectangles with the mouse.

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).
