HI, ; today I will demonstrate and try to explain my border system. I?m aware that like in my warp system again nobody will be interested ( I just dont understand why) but it is available in the Fractint Archives and who knows?? ; It is the main tool to decide when and how a part of the image is terminated and calculation moves over to the next one. For that purpose 5 different bordervalues are defined in the input screen - 2 for the outside - and 1 each for inside 1 to 3. ; The user decides if they shall be applied to the Z values or to the Iter values, or both - whatever comes first. Line 25,29,31 field B of the input pdf which is supplied show where ; You get 3 different images of course and by modifying the boder values the actual BORDER of the corresponding part can be altered. In plain language; The position inside the image. ; The names of the images show the applied version. Also parfiles are supplied. ; https://www.dropbox.com/sh/ga15ca656jyrcq4/GJPBm1fe3k ; Cheers, Albrecht
