JackOTradez's "zoom2" (as well as most of his other zooms) has apparently erroneous horizontal streaks in its black 'lake' areas when I calculate it with Fractint 20.02.4 on my Win98 SE vanilla Gateway. I've not had this problem on other images. This happens at any size image / any viewport of the image. I once saw this a long time ago in another fractal on another machine but was unsuccessful in determining what was going on at that time. Since I had not seen this particular artifact in at least six or eight years I assumed that its mechanism had been uncovered and dealt with. I have been 'given' a 2nd chance to see and ask for assistance with this particular artifact and I don't want to drop the ball this time... Does anyone else see these horizontal streaks in the 'lakes' when they create this image? <--<< ================ original message =============== Date: Mon, 20 Oct 2003 23:33:51 -0400 From: "JackOTradez" <JackOTradez@email.msn.com> Subject: [Fractint] Re: The Julia Rectangle !
