Hey, did Paul get CVS access? Paul, were you able to compile the branch with VC++ 2005 Express? I did put some tweaks in there to get everything to compile with no warnings on the Express edition. I haven't put a copy of VS.NET 2003 Academic Edition in the mail for you yet, but its coming... -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

Bug: Arbitrary precision + "center-mag=" rotation of (+-)90 degrees
by Gerald K. Dobiasovsky 31 Jan '09

31 Jan '09

Jonathan, When in arbitrary precision mode, rotating the image by exactly +-90 degrees causes the rotation angle in the TAB-window to be shown as (-)57.296 degrees (image calculation, however, remains correct at +-90 degrees). Saving the current settings as a par gets the (-)57.296 degrees rotation to be written to the file (that's how I discovered this behaviour). Changing the par's "center-mag=" by hand to (-)90 degrees and loading it into Fractint results in the same (correct calculation, but wrong TAB display), but now use of any other user interface screen (i.e. "x") causes Fractint to continue with the (-)57.296 degree angle. An angle close to +-90 degrees (not getting rounded to 90) seems ok (the nearest I managed in 1024x768 was -89.995 degrees). Rotating the image to +-90 degrees while still in floating point and *then* zooming in keeps the TAB display at the correct rotation angle, but now Fractint refuses to switch to arbitrary precision. This is DOS-Fractint 20.04p9 in MS-DOS 6.22, Fractint 19.6 behaves likewise. The original par ("longtime.par" by Noel Giffin) has a "reset=1921" entry, so this seems to go back quite a while. It certainly isn't a catastrophic malfunction, but I thought you should know. Regards, Gerald

Hello, I could use WinFract on Vista 32 successfully. But my main OS is Vista 64 bit, where it doesn't start saying to look for a compatible version. Is there one? Thanks in advance. Best Regards, Mihai Sorin Dobrescu

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.

FW: Question on Fractint Image Resolution
by Hal Lane 12 Jan '09

----------- Daniele Corradetti said ---------------------- > > ...I would need some fractals in higher resolution (more then > > 2048x2048). ... Is there any way to avoid this limit? Daniele, Tim, Rich Thompson's 'Fractint for Windows' and the current DOS Fractint version can both overcome the limit of 2048 pixels by using a configuration file to allow the creation process of fractals to use disk files and or RAM instead of the screen. (This statement is technically a bit too simple -- but let's keep it simple.) The configuration file is named: FRACTINT.CFG and is located in the directory (folder) where 'Fractint for Windows' or Fractint for DOS is installed. Fractint's configuration file data layout is pretty understandable -- just duplicate one of the existing Disk Video entries and change the "x" and "y" values -- and remove any duplicate key bindings. This works in both versions. I recommend that you don't modify any of the existing specifications in the file -- just add any resolutions you need. If you do make changes to your FRACTINT.CFG file, make a backup copy before you begin making your changes. (I'm a lazy file backup person -- I just right click the file and choose 'Copy'; then I right click 'white space' in the same folder (where there is no file name) and choose 'Paste'.) If you are not familiar with the Fractint configuration file concept, here is what the program does: - For images that fit on the screen, Fractint will display the image while it is being calculated. - For fractals that are too large to be displayed while they are being calculated, Fractint creates the image using RAM and/or hard disk drive space on your computer. The line number of the current line of pixels being generated is displayed during the image calculation (remember, there is no image being displayed.) You still must save your image after the image is completed. - Resolutions calculated using RAM and/or hard disk drive are identified in 'Fractint for Windows' beta 5's file as: "Win32 Disk Video". The DOS version of the program lists these resolutions as: "Disk/RAM 'Video'" Notes: - You don't need to specify a key binding (1st entry on the line) for your new resolutions. - Don't specify duplicate key bindings. - There is an additional entry on each line in the 'Fractint for Windows' format of FRACTINT.CFG compared to the DOS FRACTINT.CFG file format. Appended to the end of each 'Fractint for Windows' line is either: ",disk" or ",gdi" (the driver). - Order in the file is not important. However, the order of lines in the file is the order that the resolution choices will be presented to you when you press the <del> key in Fractint. - Don't use the <tab> character in the file. - Remember, images of resolutions that are *not* shown in the list of Video Mode choices as "Disk Video" *cannot* be read back into Fractint and displayed on the screen. (Sorry for the double negative above -- the positive version: Only images of resolutions that *are* shown in the list of Video Mode choices as Disk Video can be read back into Fractint and displayed correctly.) - Use a general purpose image viewer to see your Fractint images that are not of Fractint screen-viewable resolutions. - In 'Fractint for Windows' sometimes comments (next to the last field on the line) that you enter into the file do not appear in the list of resolutions displayed by the program. - I don't know what the limit on the maximum x and or y pixel dimensions are in Disk Video mode in 'Fractint for Windows' or DOS Fractint. - I have successfully calculated images of 8192 x 8192 pixels in 'Fractint for Windows' and 5120 x 4096 -- which is (1280 x 1024) x 4 pixels in DOS Fractint. I re-sized the 5120 x 4096 image in an image viewing program using a built-in smoothing algorithm and got an anti-aliased image of 1280 x 1024 pixels as the result. This image has greatly reduced 'pixilation'. Example of adding lines to FRACTINT.CFG: (with a bunch of spaces removed so the lines won't wrap around during emailing.) Original line from *Fractint for Windows* FRACTINT.CFG file: ------------------------------------------------------------ CF5 ,Win32 Disk Video,0,0,0,0, 19, 8192, 8192,256,,disk Lines added to *Fractint for Windows* FRACTINT.CFG file: ------------------------------------------------------- ,Win32 Disk Video,0,0,0,0, 19, 512, 512,256,,disk ,Win32 Disk Video,0,0,0,0, 19, 640, 640,256,,disk ,Win32 Disk Video,0,0,0,0, 19, 1300, 1000,256,,disk For the DOS format of the FRACTINT.CFG file remove ",disk" from the end of each line. I successfully created images using all 3 of the above resolutions that I added to my 'Fractint for Windows' FRACTINT.CFG file. - Hal Lane ######################### # hallane(a)earthlink.net <mailto:hallane@earthlink.net> # ######################### > -----Original Message----- > From: fractdev-bounces(a)mailman.xmission.com > [mailto:fractdev-bounces@mailman.xmission.com]On Behalf Of Tim Wegner > Sent: Sunday, January 11, 2009 1:09 PM > To: Daniele Corradetti > Cc: fractdev(a)mailman.xmission.com; Jonathan Osuch > Subject: Re: [Fractdev] Question on Fractint Image Resolution > > > Daniele, the original DOS version of Fractint had a resolution limit > of 2048 pixels.
