I don't see a reason why you would deliberately write a command line
program windows only...

Yes, there is definitely something wrong...

I didn't explicitly make it Windows only. I am just not completely sure of
the portability of the libraries used, particularly the OpenEXR library.
If there is sufficient interest, I might make the effort to clean up the
code and release the source, but otherwise I just don't want to bother.
It would probably work as-is on Linux, but I don't currently have a Linux
installation to test with.

Couldn't you do those things in HDRShop, before converting?

Quoting www.openexr.com : "OpenEXR has been ported to GNU/Linux, OS X
10.2, Win32, and IRIX. It should be fairly easy to port to other
UNIX-like operating systems."
So apparently OpenEXR wouldn't cause much trouble...

The question is: Does the OpenEXR source compile *and work* as-is on those
platforms, or does "has been ported" simply mean "someone, somewhere,
knows what must be changed to make it work on platform X"?
The big issue, though, is whether anyone even cares about this program. I
could just release the source and let the users worry about portability,
but I would have to clean it up a bit first, and I'm not going to make
that effort unless people will benefit from it.

Think of 48bpp png as "extended dynamic range". It can have 64bpp if you make use of
the alpha
chanel (rgba).

I just installed KDE 3.4 on FreeBSD 5.4 and FreeBSD automatically installed
OpenEXR along with it (it is used by KDE, though I don't think it is a
requirement). From what I can tell it's also commonly used on Linux systems
with KDE installed (though I could be wrong on that). Either way its unix
support seems quite stable.
You may like to know that we have already interally discussed adding OpenEXR
and radiance RGBE support to POV 3.7 as experimental features. I can't say
when or even if it will happen, but we are at least considering it.

My RPM dependency tree here in SuSE 9.2 shows that kdegraphics3 and
kdelibs3 both require OpenEXR.

The libraries are certainly not the problem.

Well - if the program is working well there for sure would be interest.
