This still works in version 19.61 patch 60, but is broken in version 20.0.
If you have the time, could you please find the patch between these two that
breaks this?  Thanks.

Which compiler and platform were you considering using?

Tim,

It should break in version 19.61 patch 72.

Will do, and it's a reminder to follow through and cut you a CD of all
the diffs and executables. I didn't do it before because I wanted to
do some cleanup first. I guess it would be better to cut a CD of
what I have, then if I get some cleanup done, so much the better.

I'll be using OpenBSD 2.8 w/ gcc 2.95.3 as my development platform.
I'll test occassionally against linuxPCC_2000 and solaris 2.8.  I'll also
be building on MacOS 9.1 using CodeWarrior.  Hopefully this will insure
some degree of platform independence.

My target is to create a generic library that allows for platform specific
optimizations.  I'll try and keep the input/output interfaces generic
enough to allow easy migration to different platforms.

DOS/Windows is conscpicuously absent from your list.  Its even more
conspicuous considering the heritage of fractint.

Please, please, please either get a copy of VC++ or find a partner who
will test your code on VC++; it has some things missing in its support
compared to gcc and vice-versa.

I realize I haven't done any development for a long time, so my
opinion doesn't count for much. :-)

If we wrote a GUI in WxWindows we could have a version that is
portable to Linux, Unix, Windows, and Mac.

If anyone is looking for (more) fame and fortune, there is a huge
gap in the Linux world for a decent fractal program. There are many
in the Windows world, some with a much stronger feature set than
Fractint.

I personally have little enthusiasm for a C++ port. To me the
biggest issue is moving the underlying program to a flat memory
model. This is the key to any port of Fractint. Xfractint in it's
present form doesn't count because it is just a port of Fractint's
code (segemented memory workarounds and all) to Linux/Unix.
But Tim Gilman has already proven he has ability to do Fractint
ports, and at this stage I see little reason to discourage any such
project.

There is at least one partial port to Windows by Paul de Leeuw.
This uses the native Windows 32 bit API.

Since the Allegro graphics packages has been ported to these environments,
the same might be said for an Allegro version.

I've fixed the panning problem.  Because of the complexity of the worklist
code, this fix will need a lot of testing.

Tim,

I've put patch 11 on the ftp site.  None of the executables have been
updated.  I should be able to get to update some of them Saturday morning.

Subject: Fwd: (fractint) Bug
Date: 09 Jun 2001 04:40:33 -0500

Jonathan (and/or Tim),

I forwarded this message from the regular fractint mailing list to fracdev
mailing list.

I tried running xfractint in disk-video mode (similar to MB's complaint at
the bottom of his email), and xfractint bombs with a seg-fault in *any*
geometry size, as long as you use the "-disk" command-line switch.  Oh,
I observed this in v20.1.07 and v20.1.11

Try this:

1. Display some fractal from a type that has parameters. Set passes=t.
2. Ctrl-E -- evolver/explorer. Turn it on. Use F6 and set two parameters
 to x and y respectively, leave the rest normal. Accept the F6 screen and
 change "show parameter zoom box" to "yes". 3. Page-up to get zoom box,
 move it with a ctrl-arrow, enter.
4. Space, turn off evolver/explorer, enter.
5. Observe something the manufacturer definitely didn't intend.
6. Hit 'b' to save parameters.
7. Observe something else the manufacturer didn't intend.

Type: bug
Reported-against: 20.01.10
Severity: low
Workaround: yes


Incidentally, the latest developer patches act weird when AF7 is bound to
 1024x768x256 disk-video. Hitting it produces an error message that seems
 to say something about not enough memory (on a 64 meg box!) after which
 it works anyway(!) -- this never occurred with 20.0 or 19.x.<br

Subject: Colors not saved correctly in Xfractint .par files
Date: 10 Jun 2001 12:02:39 -0500

Jonathan,

Using Xfractint 20.1.11, I was re-creating some fractals from .par files I
saved back in '99. I have discovered that if you re-write the .par file
using version 20.1.07 or better, the color info is not saved correctly. It
saves the color info as: "colors=000<254>000" instead of the long info.
This even happens if I use one of Jim Muth's FOTD par files, and then
re-save it using Xfractint 20.1.07 or 20.1.11. Then when you try to
re-create the fractal from the new .par file, all you get is a black
screen (nothing being drawn to the screen.) I imagine this has to do with
the true-color fix for Xfractint, but I have no idea how to go about
fixing it.

I'll have a look.  Thanks.

Several loyal list members noticed that the [fractdev] was missing
from the subject line of messages posted here. Last time I sent a
majordomo config file, the subject_prefix command had wrapped
and was embedded in a comment. If you see it in this message, I
succeeded in fixing it.

Off topic: I just got back from Duluth, MN where I ran in Grandma's
marathon. If you go to:

http://www.onlineraceresults.com/results/results.cfm?EventID=3169

and type in wegner for the last name, you will find my results plus
those of a Carl Wegner who finished 10 minutes ahead of me,
despite being 60 years old :-)

I installed it a while ago, and have no complaints. I haven't used it a
lot though.
