Could you e-mail them to "christoph", located at "lipka-koeln" in ".de"?
Thanks a bunch!

Hum... maybe then I need to hack my own? I gather they're actually GIF
file "containers", with the data encoded as two side-by-side images, the
left one carrying the high-order byte and the right one the low-order
byte (with the color palette apparently being ignored). So it shouldn't
be too difficult to construct: All I probably need to do is convert to
greyscale, expand the canvas to the right, fill up with black or just
some random noise, convert to indexed colors (making sure the export
color palette is a continuous grey scale), and save as GIF, right?
The only problem I see is that this might accidently add some gamma (or
other nonlinear influence) to the picture that is not intended, and
defies the original purpose of my request, which is to get the gamma
conversion right for all input formats.
Any idea how to get this straight?

Sorry it is way beyond me :(
You can download the source code for fractint, though.

Who uses POT files anymore? Maybe support for it could be deprecated.

I've certainly not used it more than once and that's when I started using Pov.
Memo to self: Finish that plasma landscape fly through :)

Fractint video drivers don't work on Windows XP and above and Winfract won't
colour cycle. :(

I use PPM's from time to time - they are so simple to write that I don't
need any libraries and can create them from any language I choose.
They are even easier if you use the ASCII versions.
I'm off on holiday in 2hrs time for a week so can't supply images now
:-( I think sleep is needed.
I do know that many programs - possibly including POV 3.6 impose some
non-standard restrictions on the format of the ascii header. The spec -
such as it is - specifies that the various items of header only need to
be separated by white space, but several implementations say that
certain bits of header need to be separated by newlines and that certain
other bits need to be on the same line. Obviously the ideal
implementation would read anything but write in the normal layout.
If you've not got these in a week and still have a use for them I'll see
what I can do. Thanks for the work you're putting in here.

Nobody, I guess. I have a couple of them that I keep for sentimental reasons
:-) support could indeed be discontinued.
Like Stephen, I have not used Fractint or Winfract for maybe 10 years....

Re IFF/PGM/PPM test images:
IrfanView(www.irfanview.com) for Windows can save .PGMs & .PPMs(24-bit) from a
host of imported formats,while Deluxe Paint II(DOS) by Electronic Arts creates
..LBMs(included is CONVERT.EXE,which can change a few formats,such as BMP,to
LBM)-see www.vetusabandonware.com(Multimedia panel) for 1994 ver 3.0.
Hope this helps,if you've not already converted your images.
