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
