Patch 3
by Jonathan Osuch 06 Aug '05

06 Aug '05

Tim, I am about ready to release patch 3. Here is what is new: Started the cleanup of the docs. Cleaned up the map directory. Fixed the Xfractint Makefile so that install would run. Added an uninstall. Fixed Xfractint so that it can be run from an arbitrary directory and still use the directory settings in sstools.ini. Note that the install/uninstall of Xfractint still needs to be done as su. I don't see any way around this. Jonathan

Bug in version 20.4.1 (new drawing modes for passes=orbits)
by Gerald K. Dobiasovsky 16 Jul '05

16 Jul '05

Jonathan, In rectangle orbitdraw mode, using "maintain screen coordinates": The <F6> image coordinates get munged when changing anything at the <F2> screen coordinates prompt, provided the <F6> image coordinates had a non-zero rotation and/or skew angle. The <F6> coordinates "lose" their original angle/skew data, and magnification and x-magnification are grossly different than before. Below I've included the part of the source where (I think) the mistake has been made (unaltered save the four additional comments pointing to the offending lines). Regards, Gerald -------------------------------- 8< ------------------------------------ File: prompts2.c Line: 2347 In: get_screen_corners() svxxmin = xxmin; /* save these for later since cvtcorners modifies them */ svxxmax = xxmax; /* and we need to set them for cvtcentermag to work */ svxx3rd = xxmin; /* <-- xx3rd instead of xxmin ? */ svyymin = yymin; svyymax = yymax; svyy3rd = yymin; /* <-- yy3rd instead of yymin ? */ if (!set_orbit_corners && !keep_scrn_coords) { oxmin = xxmin; oxmax = xxmax; ox3rd = xxmin; /* <-- xx3rd instead of xxmin ? */ oymin = yymin; oymax = yymax; oy3rd = yymin; /* <-- yy3rd instead of yymin ? */ } -------------------------------- 8< ------------------------------------

Patch 6
by Jonathan Osuch 02 Jul '05

02 Jul '05

Tim, I'm going to try to wrap up patch 6 this week. So far, this is what I have: Fixed FPUcplxdiv and FPUcplxlog routines in fpu087.c to match assembler code. Fixed it so spaces are recognized in PAR entry names. Fixed evolver parameter entry. Fixed hypercomplex fractal type to turn off symmetry when a cj parameter is used. Fixed the plasma type to show the value of the parameter that is actually used in the image generation. Fixed the plasma type so that a parameter file uses the included colors instead of the default colors. Revised the plasma type prompt to reflect the values that could actually be used. Fixed inside=atan and outside=atan to use the full color palette instead of limiting to 180 colors. Modified the resume code to remove the Xfractint specific sections since they are no longer needed. I still need to move all this over to DOS and make sure nothing is broken. There are other fixes I would like to include, but haven't done them yet. Jonathan

Progress towards version 20.04 patch 1
by Jonathan Osuch 22 Apr '05

22 Apr '05

Tim, Despite the silence, I have started once again to make progress towards getting the next patch ready. I was actually fairly close before I start working in Illinois again. It only took about two weeks to get an internet connection, then another week or two to figure out how to send email. It won't take nearly so long next time, since I've managed to find out how to make Evolution use sendmail. Very handy, sendmail. Hopefully, this list won't know the difference. Using mandy for a CVS repository is problematic occassionally because the ISP I use in Illinois has some server and/or DNS issues. However, it is working and I have managed to export a usable source tree from it. It's a bit of a pain to have to enter my password all the time, but it's now memorized so it isn't all that bad. It seems to me, though, that it might be getting sent across as clear text when I have to run a command from a terminal on my machine. This happens when I want to make a diff file. Jonathan

CVS and other news
by Jonathan Osuch 27 Feb '05

27 Feb '05

Tim, I put the fractint/fractint-float/allegro CVS repository in the fractint directory. However, I am not able to checkout a module at this point in time. It could be that the permissions are messed up. I'll look into it a little today. Tomorrow, I'm heading back to Clinton, Illinois, for about ten months to continue the project that was cut short last year. I won't have internet access until March 3rd, and don't know how long after that it will take before I get email working again. The good news is, I'll be able to pay my bills again and I'll have more time to spend on Fractint. Jonathan

Hi there, Owing to the ridiculously large amount of junk mail I receive (at the time of this writing, over 3,000 spam messages each day), I have installed software that screens my incoming mail and only accepts mail from real people. Your address isn't currently known as one belonging to a real person, so your recent message with the subject of "Mail Delivery (failure fractal-art-owner(a)lists.fractalus.com)" is being temporarily held. To confirm you really sent the message, to deliver it to my mailbox, and to put your address on a list of approved senders (so that you never see this confirmation request again), please send an empty message to the following address, or just reply to this message: dmj-confirm-1108015691.12041.2da1cb(a)fractalus.com You will need to do this within seven days, or your message will be automatically deleted from the queue. Please understand this is nothing personal; I want to hear from you, but it's getting harder to find the important messages in my inbox with all the junk crowding it out. If this works out, you'll only ever have to do this once, until your e-mail address changes. If you're replying to these confirmation requests and your mail still isn't getting through, please use the feedback form on my web site. --Damien P.S. If you sent your message as "HTML", please re-send it in plain text. HTML mail is all too often used by junk mailers and by viruses; it's just not safe to read. If you send me HTML mail, I will eventually read it when I can open it safely, but it may take me (much) longer to get to it. P.P.S. If you're a spammer who actually reads bounce messages, don't bother confirming. Your message is not welcome, I do not want your product, your service, or your web site. Remove me from your list. Do not pretend that I have opted in; I never do. No legitimate business operates through spam. By using spam, you are confirming that you are disreputable, sleazy, the very dregs of the internet population.

Mathtolerance variable
by Jonathan Osuch 13 Jan '05

13 Jan '05

Tim, I've had an extended email exchange with Charles Crocker about a problem he was seeing that relates back to the mathtolerance variable. I see several problems 1) Mathtolerance is not saved in GIF's, 2) Mathtolerance is not saved in PAR's, 3) Mathtolerance is not ever reset to default values. I understand the original intended use of the variable, but with Jim Muth including it on a regular basis with his FOTD it looks like we should incorporate it into the fractal_info and history_info structures. To do this will require increasing the size of the fractal_info structure, which then gets saved to GIF's. Do you recall if this will cause problems with older versions of Fractint reading these GIF's? Jonathan

Fractint/Xfractint directory structure
by Jonathan Osuch 03 Dec '04

03 Dec '04

Tim, I intend to restructure the Fractint/Xfractint directory to look something like: Fractint Common (including header files) DOS (mostly assembly language, but come C) Unix Maps Par Formula IFS Lsystem This should allow me to maintain 3 source trees instead of the current 6. The sixth tree is from having already started this project. The others are Fractint, Xfractint, Fractint-floatonly, Xfractint-floatonly, and Experimental (Allegro). I did a test to see if I can do this under DOS, and I can. It requires editting each file to change the location of the header files, and changing the make files. Which is no different than what is required under Linux. I thought about putting the header files in a separate Headers directory, but that would require more #ifdef's because of the different usage of '/' and '\' in DOS and Linux. If there are no major complaints, I am going to restructure and then start a new CVS repository for each. Any thoughts or advice before I start this? Jonathan

Xfractint and mandel type
by Jonathan Osuch 14 Nov '04

14 Nov '04

Tim, The Xfractint code in calmanfp.c isn't handling periodicity correctly. If you set periodicity negative so that you can see where it catches the orbits, you'll notice that the white (color=7) area doesn't appear. This seemed like a simple problem... There is a brace in the wrong place and the code wasn't updated to reflect changes made in StandardFractal(). I've gotten it close, but it still isn't an exact match with what is drawn with debug=90. Hopefully I'll get a patch out by the 20th, when my Cisco CCNA class starts. This could be tough because I am currenly studying to take the CompTIA Linux+ Certification exam. Jonathan

Tim, Have you tried the newton and newtbasin types using Xfractint lately? They seem to be broken on my machine. Jonathan
