Some replies to Paul N. Lee's questions about running Fractint under DOSBox and Vista.Hopefully this information will be helpful to other mailing list members. To begin with DOSBox is an emulator that allows old DOS games and applications to run under modern OS's like XP and Vista.Go to http://www.dosbox.com/ to learn more and download both DOSBox and D-Fend Reloaded.I use the latest versions- version 0.73 for DOSBox and version 0.9.3 for D-Fend Reloaded. DOSBox itself uses a command line -it looks like old DOS.D-Fend Reloaded provides a familiar graphical interface to simplfy configuring DOSBox.To get the maximum speed when setting up D-Fend Reloaded I choose Max under the CPU section of the hardware profile.Other values I left at their defaults.
I've run DOS Fractint under Linux using QEMU, works quite well. I usually use XFractint, though. [snip]
Finally about large gifs.The Disk/RAM entries in fractint.cfg can be edited in Notepad to provide custom resolutions.I copied some lines from the default Fractint.cfg as an example.The cfg file must be saved in the old txt format. AF1 ,Disk/RAM 'Video' , 3, 0, 0, 0, 11, 800, 600, 2,Full-Page L-Jet @ 75DPI AF2 ,Disk/RAM 'Video' , 3, 0, 0, 0, 11, 1600, 1200, 2,Full-Page L-Jet @ 150DPI AF3 ,Disk/RAM 'Video' , 3, 0, 0, 0, 11, 768, 960, 2,Full-Page Epson @ 120DPI AF4 ,Disk/RAM 'Video' , 3, 0, 0, 0, 11, 960, 720,256,Full-Page Paintjet 90DPI <== Edit me!

AF5 ,Disk/RAM 'Video' , 3, 0, 0, 0, 11, 800, 600,256,For Background Fractals AF6 ,Disk/RAM 'Video' , 3, 0, 0, 0, 11, 2048, 2048,256,For Background Fractals In the AF4 entry the value 960 has been changed to 2400.This is the horizontal resolution.The value 720 has been changed to 1800.This is the vertical resolution.The value 256 which is the number of colors is unchanged.Note that if either horizontal(x) or vertical(y)values are greater than 2048 Fractint plots uses the passes=1 mode.This can slow things down significantly.
Add one for 32768x32768. Lovely images! If you're interested in doing fractal prints, divide the dimensions by 300 to get the physical print size.
