<David> An additional way to create 3:2 aspect ratio fractals
"David M Fisher" <sunfish@intercom.net> said: (original posting: Date: Sun, 22 Apr 2007 14:16:01 -0400)
The normal screen resolution of monitor displays is in a ratio of 4:3, ie, 800x600. Is it possible to render in another resolution without distortion?

Take a look at the 'v' screen and its documentation. Set: Preview Display? (no for full screen) = yes Auto window size reduction factor = 1 Final media overall aspect ratio, y/x = 0.66 Crop starting coordinates to new aspect ratio? = yes
Another way to create fractals of essentially any desired resolution is to add lines to your FRACTINT.CFG file. The lines from my FRACTINT.CFG file I pasted below may wrap in the various email systems. You can make a backup copy of your FRACTINT.CFG file and use any ASCII text editor to look at -- and add lines to -- your FRACTINT.CFG file. After you add lines to FRACTINT.CFG, when you press the <DEL> key in Fractint you will see your new lines as new resolutions able to be chosen for the calculation. ; FRACTINT.CFG File ;key name of adapter/mode | AX | BX | CX | DX |mode| x | y |clr| comments ;=========================================================================== ====== F2 ,IBM 16-Color EGA , 10, 0, 0, 0, 2, 640, 350,256,Standard EGA hi-res mode F3 ,IBM 256-Color VGA/MCGA , 13, 0, 0, 0, 3, 320, 200,256,Quick and LOTS of colors ... The 2nd and 3rd lines below are Disk 'Video' mode lines I added to my FRACTINT.CFG file: ,Disk/RAM 'Video' , 3, 0, 0, 0, 11,1024, 768,256,For Background Fractals ,Disk/RAM 'Video' , 3, 0, 0, 0, 11,2048,1536,256,/For Bkgnd 2*(1024 x 768) ,Disk/RAM 'Video' , 3, 0, 0, 0, 11,4096,3072,256,/For Bkgnd 4*(1024 x 768) They let me create fractals of twice or four times the final resolution I want. After calculating the 'oversized' image I use my graphics software, CompuPic, to create an anti-aliased 1024 x 768 .jpg of the fractal from the oversized version. Most anti-aliased 1024 x 768 fractals are clearly visually superior to the same one calculated directly as 1024 x 768. You may want to consider using this technique for the fractals you sell. A few experiments should tell you whether this method provides any visible improvements in the printed results. See the Fractint docs for more info: "6.3 Customized Video Modes, FRACTINT.CFG If you have a favorite adapter/video mode that you would like to add to Fractint... if you want some new sizes of disk-video modes... if you want to remove table entries that do not apply to your system... if you want to specify different "textsafe=" options for different video modes... relief is here, and without even learning "C"! You can do these things by modifying the FRACTINT.CFG file with your text editor. Saving a backup copy of FRACTINT.CFG first is of course highly recommended! ..." Typing: FRACTINT MAKEDOC at the DOS command line will create the file FRACTINT.DOC. It is an ASCII text file, not an MS Word document as the .DOC implies. I rename the documentation file to FRACTINT.WRI so that the WRITE text editor (which can handle larger files than NOTEPAD) will edit the FRACTINT.WRI file when it is double clicked on. - Hal Lane ######################### # hallane@earthlink.net # ######################### No virus found in this outgoing message.
