Can someone do me a favor and convert this test image into the following
(allegedly) POV-Ray supported formats? (Obviously, conversion to
greyscale is needed for some of these. I'm also aware that the test
image will not make full use of the "depth" of some formats.)
IFF (various variants)
(Is there any software out there that still writes these?)
PGM (maxval <= 255)
PGM (maxval <= 65535)
PPM (maxval <= 255)
PPM (maxval <= 65535)
(Again, are these actually still relevant these days?)
POT
Furthermore, I'd like to make sure I didn't miss any files that can be
used for input in POV-Ray; I already have accounted for:
BMP
OpenEXR
GIF
Radiance HDR
JPEG
PNG
TARGA
TIFF

As far as I know, the WinFract (?) is the only program that generates POT
files... or am I wrong?
I made the other images, but they are 1 to 3 mb in size each!!!

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.

Ah! Fractint is what I mean of course!

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 :)
