Roger,

My apologies for bothering you but I can find little help via Google or forums for something a simple as how can I run xfractint on Kubuntu 12.04 with your parameters.

I would like to run it as a batch using something like:

xfractint PARMFILE=myFractInt.par FORMULAFILE=mfr_12.frm

or

xfractint @myFractInt.par/58484-w7a // didn't work because it seems file names must be 8.3 format

Yes, the 8.3 format is still used because removing it breaks some of the screens which are hard coded.

xfractint @FractInt.par/58484-w7a appeared to read the formula 'multifract_12 but only if I included it in the FractInt.par, however, it then crashes with a segment fault error.

The formula does get read in, but then it crashes, as you say. This is usually an indication that not enough memory has been allocated. I'll look into it. Jonathan

I run XFractint on Aptosid (Debian Sid). And just noticed that when I press Esc and go to the main screen, the "@" option does nothing but return me to the starting Mandelbrot. Doesn't even give me an option to load a file. That's XFractint 20.4.10. david gnome@hawaii.rr.com authenticity, honesty, community ---- Roger <aretae@magma.ca> wrote:

I am using xfractint version 20.04.10.

What I would very much like are some examples of how to run your par and frm files in xfractint?

It would be nice, for me anyway, would be to put 58484-w7a into its own file, say 58484-w7a.par or 58484w7a.par and have that and mfr_12.frm in the current directory then run:

xfractint @58484w7a.par/58484-w7a (this can't find the multifractal_12 file entry even though mfr_12.frm is in the current directory)

and of course not have a segmentation error. (Any suggestions for avoiding this problem?)

If you could provide me with some examples, recommend methods, good xfractint tutorials, or useful Google search terms that would point me in the right direction I would appreciate it very much.

David, I have just started to play with xfractint and I have Kubuntu but I am having problems understanding basic usage. Using Google etc I am having difficulty finding basic usage examples. I thought that something like: xfractint parmfile=58484w7a.par formulafile=mfr_12.frm would work but I always get an error message stating that the formula file can't be found. If it is not too much trouble would you explain to me the procedure you use with Linux to quickly and efficiently load and display the par files that are offered in this forum and elsewhere?

Sorry, I must have left my brain somewhere out of the circuit. Pressing SHIFT-2 makes the @ sign. And that works just in in XFractint here. Doh!

I'd go back under my rock, but it's already in my head.

Jonathan, Thank you for your reply. I created a 'sstools.ini' file in the current directory with 'currdir=yes'. In sstools.ini I also set the working directory but xfractint still cannot find mfr_12.frm. Is there a way in which I can confirm that xfractint is picking up 'sstools.ini'?

xfractint @58484w7a/58484-w7a

Where the par filename directly follows the @ symbol and the par name follows the '/'. The formulafile and the formulaname are provided in the par. As long as they match the actual formulafile and formulaname, this should work.

You may also put the par and frm files in the current working directory and then use 'curdir=yes' (this can be put in your sstools.ini file).

On my system, I don't run 'make install', so I use a call to ./xfractint because it resides in the current directory. With the mfr_12 formula (and mfr_10) you will still get the segmentation fault, so this is a bad example.

I believe the sstools.ini file you need to modify is located in the directory: /usr/share/xfractint

Hmm, there's no way to have it installed on the system but use an sstools.ini file/folder in the user's home folder?

Unless the install was modified to put the files some place other than /usr.

Yes, there is. You need to rename the sstools.ini file in the usr/share/xfractint directory. This can be done from a terminal in that directory by using: sudo mv sstools.ini sstools.old

Then xfractint won't find the sstools.ini in the default location and will look in the current directory.

Ah, thanks. That'll enable me to use the same sstools.ini with xfracint and DOSFractint. -- David gnome@hawaii.rr.com authenticity, honesty, community http://dancingtreefrog.com

Roger,

Great, that worked with respect to reading the files, not the segmentation error.

I do have a fix for the segmentation fault in my version. Unfortunately, the multifractal_12 formula executes once for each pixel and then bails out. This leads to a very dull image. I'll keep working on it. Jonathan

Albrecht,

do I read you well that there possibly is a way to improve calculation precision? Please tell me more. Thanks

No. What gave you that impression? If you start Fractint with the option debug=90, this forces the formula parser to use the C code (which is what Xfractint uses), and then if you run the multifractal_12 formula you will see the problem I'm trying to fix. The parser assembly code has a higher precision than the C code, but I don't think that precision is the problem. Jonathan

Jonathan, Re above ref. 5484-w7a and others generated with Multifractal_12 I am trying to get a definite reply if my stripping of unneeded digits after the dot. alters the calculation of an image. This concnerns variables and commands as they appear on the input screen. The same par-files generate different images compared to Multifractal_10 but that may have othere reasons. I repeat the link which contains some images and the latest edition of the frm https://www.dropbox.com/sh/8ze5mwy9er8gv4x/KqXX9Ge1u_ thanks for your assistance! Albrecht

The short answer is yes, they are different. However, the differences may not be significant, or even visible. You can compare the two images by generating them at the same resolution, load one of the images (using <r>), set debug=50 using the <g> screen, and then load the other image (using <r> again). In addition to the differences shown on the screen, the file cmperr is generated that lists each pixel that is different and what the difference is.

Jonathan

Thank you, Jonathan. That was good advise.. I compared 2 images apparently identical, generated with MFR10 and MFR12. The second version shows more details and simply is the better one, inspite of my stripping unneeded digits. Here is a link, the MFR12 version is first and the results as 3rd image- That clarifies. Thanks, again, Jonathan. Albrecht https://www.dropbox.com/sh/ohfg5f1p9xbk5qc/Kp0gwrb1iv

No, using multiple cores would require a major rewrite of the code.

Oh, well. I guess it must be the jump from the old laptop's 2.8GHz old-style Celeron that makes it so fast. -- David gnome@hawaii.rr.com authenticity, honesty, community http://dancingtreefrog.com
