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

Zoom box movement in autokey files
by Gerald K. Dobiasovsky 15 Jan '04

15 Jan '04

Hi... Not that it matters much, since fractint's autokey feature doesn't seem to be used by many: When playing an autokey file that was created for version 19.x and earlier, panning the zoom box now moves it too far, resulting in a much different image than was intended. This can be checked using demo.bat, demo.par and basic.key from the autokey files created for version 19.x and still part of the fractint distribution, choosing "Basic commands demo". (Not to forget: One has to change line 25 in basic.key from "DOWN * 2" to "DOWN * 4" to adapt it to the additional two prompts on the <x> screen introduced in, I think, fractint 20.1.) Regards, Gerald

fractint.org domain
by Tim Wegner 30 Dec '03

The fractint.org domain name comes up for renewal on January 29. The name is currently registered with network solutions. For whatever reason, I have built up a negative image of network solutions over the years, though I can't say I've ever personally had any problems. I'm considering dyndns.org because they have give me reliable free DNS service, and are cheaper than network solutions (flat $15/year). I wouldn't mind giving the business to xmission.com because they have been so great helping with the mailing lists, though it looks like I can only use them if I have an account (not practical because they are in Utah). Any suggestions/recommendations of good domain name providers? FWIW, fractint.net is available. Fractint.com is taken. (For my purposes, fractint.org is sufficient). Hmmm, the fellow who has fractint.com might be able to renew fractint.org, I'll ask. Tim

Resuming images across ports
by Jonathan Osuch 29 Dec '03

29 Dec '03

Tim, This was on the Fractint bug list: > Another thing : It's not possible to finish an image that was started on > xfractint with (MS)DOS FRACTINT ( and vice versa ), because the > fractint002-extensions are different for those 2 ports. In my version, I've taken out any Xfractint specific code for the resume logic because the macros that handle a variable number of parameters have been updated. However, because of how we are saving the data, I haven't been able to figure out how to make the saved extentions the same size. We use the sizeof() function to determine how many bytes to put in the resume memory and by the time we get to the GIF routines, we have no idea what the size of the different variable are. We would need to make the conversion in the resume routines instead of in the GIF handling routines. Very ugly, and I don't want to do it. Does anybody see a way to get past this, and how many people really need this to work? BTW, there is some documentation at the bottom of the resume routines in fracsubr.c that appears to belong elsewhere. Do you have any idea where? Jonathan

Resuming images with formula in a PAR
by Jonathan Osuch 29 Dec '03

29 Dec '03

Tim, Also on the Fractint bug list is a problem with resuming images when the formula is in a PAR file. Fractint can't find the formula. Do you remember enough about how you modified the find_file_item routine in miscres.c to make the change easily? Jonathan
