maybe you have an answer ! I have the answer. The format of the .GIF image file must be corrupted in some way in the color map table.
If you Reload <R> the image (as I did) and type <e> <Enter> to open the Color Editor, and then repeatedly type the period key "." look carefully and you will see that Fractint is only rotating/shifting the bottom/lowest 16 colors -- not all 256. The only way that this could happen in so many different versions of Fractint is for the format of the color map inside the image file itself to be nonstandard in some way, that makes Fractint only rotate the bottom 16 colors. The reason that 58484-54.GIF shows no rotation in the image at all, is that the image has no pixels colored with the bottom 16 colors of the color map -- 16 shades of "gold". In the <e> <Enter> the Color Editor, typing repeated "." "Rotate Color Map One Step" commands shows the bottom 16 "gold" colors rotating -- but there are no pixels of those 16 "gold" colors in the image to be rotated, so the image doesn't change at all. I Reloaded <R> both images (58484-54.GIF and 58484-55.GIF) into both these Fractint versions: - Richard's Fractint for Windows beta 5, and - Jonathan's 2018-01-26 SDL2-fractint-20.05alpha and got identical results -- only the bottom 16 colors of the color map can be rotated. The item common to both these tests is your image file that I downloaded from your Dropbox. What version of Fractint was used to write out these images you have in your Dropbox? ⇐ ⇐ - Hal Lane ######################## # mailto:hallane@earthlink.net ######################## From: Albrecht Niekamp [mailto:xxfractalist@outlook.com] Sent: Saturday, February 3, 2018 9:33 AM To: Harold Lane <hallane@earthlink.net> Subject: fwdd to Hal maybe you have an answer ! -------- Weitergeleitete Nachricht -------- Betreff: [Fractint] The Riddle Datum: Sat, 3 Feb 2018 13:29:05 +0100 Von: Albrecht Niekamp mailto:xxfractalist@outlook.com An: mailto:fractint@mailman.xmission.com The Riddle ; If you dig into the sand of 58484-05 you will find all kinds of hidden treasures and surprises. Images 9,10,15,18 and others have proven it. This I had in mind when I programmed the latest version af MFR and especially the new warpeffect two years ago : to turn Fractint into a fantastic fractal toy. Today I found a special surprise: An image where only the middle part is available for color cycling. This is NOT a fractint error, if copied it into the SVN dosbox it still can be modified and zoomed into, but the riddle remains, even if generated from a par. The zoom, taken from the outer parts has no colorcycling at all but they can be switched by changing the map. The question goes out to Jonathan - can you analyze what´s happening here? It is not the cycle range command !

Mike, thanks. Remember you mentioned trying to transform the MFR software to fracton. Please check the Start-Kit where you find basic versions for all frms used and the input table with a quick reference guide. https://1drv.ms/f/s!AmWYApv7ZBFGgZ0htOy8PqrwOqvIjA Albrecht Am 03.02.2018 um 17:59 schrieb Mike Frazier:

OK thanks. It would be fun to explore some of your nice fractals. I will give it a try. -- Mike Frazier www.fracton.org

Nice find Hal! Yes and no... The thing that I did *not* realize, was that the restriction of the number of colors cycled by Fractint is a feature! It appears that the values set in the two <Y>-screen Cyclerange fields are written by Fractint into the image file's extension blocks that Fractint appends to the .Gif image as it is written out.
This is in addition to their also being written out to PAR files: e.g.: "cyclerange=1/15" as was also in Albrecht's: ... 58484-55 { ; The Riddle, and his ... 58484-54 { ; The Riddle_Zoom ------ Albrecht said: --------- ...I found, that a default value had been overwritten. Exchanged the exe against a new one, but that did not help completely, so I made a par and changed the cycle range which in other pars never occurs to 1. Now it seems ok, can you confirm that 1 is the default value ? Thanks, Albrecht ------------------------------------ The Fractint docs say: ... "By default, color numbers 1 to 255 inclusive are cycled." so, unless you had changed them and forgot that you had, it's a mystery how they got set to: ... "cyclerange=1/15" If: - no cyclerange value appears in a parameter file, or - in the .GIF extension blocks of an image Reloaded <R> into Fractint, Fractint uses the default values 1 through 255. You can see these values (as I did) on the Y-screen when starting a new Fractint session. I did a test where I: - Reloaded your strangely-color-cycling Riddle image into Fractint, - Observed that the Cyclerange on the Y-screen was cyclerange=1/15, - Set Cyclerange to 1 through 255, - Wrote out the image to a new file name, - Exited Fractint, - Ran a new instance of Fractint, - Reloaded my new image file into Fractint, - Observed that the Cyclerange on the Y-screen was cyclerange=1/255, - Used the <e> <Enter> color editor and repeatedly typed the period <.> key, and saw that all 255 color map locations were being cycled correctly. As I said at the beginning of this email, I hadn't realized that the values set in the <Y>-screen CycleRange fields are written into Fractint's extension blocks which are appended to the .Gif image file when Fractint writes it... - Hal Lane ######################## # hallane@earthlink.net ######################## -----Original Message----- From: Fractint [mailto:fractint-bounces@mailman.xmission.com] On Behalf Of Mike Frazier Sent: Saturday, February 3, 2018 11:59 AM To: Fractint and General Fractals Discussion <fractint@mailman.xmission.com> Subject: Re: [Fractint] The Riddle Nice find Hal! -- Mike Frazier www.fracton.org _______________________________________________ Fractint mailing list Fractint@mailman.xmission.com https://mailman.xmission.com/cgi-bin/mailman/listinfo/fractint --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus
Thank you, Hal It can be, you`re right because I remember of a flashing warning by Fractint, have the 20.04.12 think it´s the last one. Please check the Roygbv.map. Am 03.02.2018 um 16:42 schrieb Harold Lane:

Hal, unfortunately this was not the happy end for today´s issue because I found, that a default value had been overwritten. Exchanged the exe against a new one but that did not help complletely so I made a par and changed the cycle range which in other pars never occurs to 1. Now it seems ok, can you confirm that 1 is the default value ? Thanks, Albrecht Am 03.02.2018 um 17:59 schrieb Albrecht Niekamp:
