I have made a new program for editing high color resolution images.  It is
a windows GUI application written in Delphi.  

Currently only very few editing functions are available:
brightness/contrast/gamma adjustments and a thresholded smooth filter.  If
you have suggestions what functions you would find useful in addition i
would be pleased to hear.

The program is not very intensively tested so there might be bugs.  Also
some quite essential features are not yet implemented like undo and saving
of program settings.  Handling of larger images has to be improved too.

Comments are welcome of course.

Nice start!! but I missed a feature in the todo list, unless it is what 
you mean with "color correction adjustments". The contrast curve 
corrections Kari does to his images.

I renderd the photon scene from the include menu with +fn16. Loaded it 
in your program, copied it, pasted it and suddenly the sky was pink. 
When saving this pink sky image and reloading it the sky is ok again.

The brightness stepps, when using the buttons, are a bit big i.m.o.

Altough it says so in the doc, the programm doesn't ask to save the 
image on exit.

Gamma correction?

Of course more detailed control over the used function would be
interesting, but i'm not sure how you want to define that function.

Sounds strange, i will have a look into it.

BTW copy and paste should not be used this way since they only work with
8/24 bit accuracy.

I noticed that too.

Oops, sometimes i simply forget i did not yet implement a feature...

Thanks for the comments.

So it's essentially a spline.

I will consider it.
