Re: [Fractdev] Question on Fractint Image Resolution
Daniele, the original DOS version of Fractint had a resolution limit of 2048 pixels. However it also has a means of generating multiple images and piecing them together, see the documentation. I believe this effectively overcomes the limit. (Sorry for not being more specific, it's been a while since I looked at this.) Rich Thompson has created a Windows version that may overcome that limit. You didn't mention which version you are using. I am cc'ing both Jonathan Osuch, who has been mainting the current version, and Rich. However my suggestion would be to join the mailing list at: http://mailman.xmission.com/cgi-bin/mailman/listinfo/fractint since there are many people who could help you better than I can. Tim
Dear Tim Wegner, I'm a mathematician from Pisa, Italy. Let me tell you how glad I am finding a new update of FractInt for Windows Vista. Indeed this program means a lot for me since I was just a kid when it was released and I grew up with its fractal. Most of my love for mathematics probably came from it.
Anyway, I got a problem with the maximum resolution of Fractint. Indeed I would need some fractals in higher resolution (more then 2048x2048). I saw in some post of yours that the max resolution 2048 is crucial. Is there any way to avoid this limit?
Thank you for your answer Best Kinds

Daniele, It sounds like you are using WinFract (the DOS Fractint limit is 32768x32768 using disk video, or is based on the available video memory). There is an arbitrarily set maximum of 2048x2048 pixels for the image size in WinFract. I modified my version to use 4096x4096. There is a lack of memory problem that prevents this from working at 4096x4096. However, I was able to generate an image at 3072x2304. I will need to look into this further. Also, there are supposed to be scroll bars on the window that don't appear for some reason. Jonathan

Does the "pieces" feature still work? As a I recall a PAR files is created that generates parts of an image that can be pieced together with an outboard utility. I'm not sure what limitations the utility has, but it wouldn't be too hard to resurrect it and, I would think, make very large images. Of course once I would have said 3072x2304 was more than very large! I've got a Canon i9900 that maxes out at 4800 dpi x 2400 dpi. That means a 13x17 inch paper represents 62400 x 40800 pixels. Hmmm, would be interesting to try to utilize all of that! I haven't experimented for a very long time, but I seem to recall that color combinations that look good on the screen are too dark and saturated to print. Tim
Tim, Here is the response I received from Daniele: Dear Tim, Hal, Jonathan and Marcus, thank all of you for your answers! Indeed I was using the last version of WinFract (for Marcus, I'm using this version http://www.fractint.org/ftp/current/windows/ ). I didn't know that the DOS Fractint was supporting such higher resolution. This represents a good solution. Thank you Hal for your detailed instructions. Dear Jonathan, if you have a modified version of WinFract which reaches a something near to a 4096x4096 I really would appreciate it, even if is not bugless. Could you send it to me?

Yes, the "pieces" feature is still in Fractint. When I increased the artificial limit in WinFract to 4096x4096, I was able to generate an image of maximum size 4087x4087. Increasing the artificial limit to 8192x8192 made no difference.

It has been a long time for me, as well. I don't recall a specific problem with the colors, other than the two images never match. Even with the color matching in Windows with the monitor and printer color profiles set up, the pictures (photos) I print don't always match the screen image. Jonathan
