Subject: [Fractint] re: Qs re higher resolutions w Fractint w a new computer

THanks much, Hal! I usually print at 1280 x 1024, which is about as large as I have been able to push. I do not understand the disk video mode, though I've tried it- didn't really  know what "happened." Do you allow it to run, then do a SAVE just as you would any other fractal, only sight unseen?

 

I am such a novice, but trying to learn. It was only this year, I guess, that I learned from Paul how to increase my resolution, which I'm very proud of! An old dog CAN learn new tricks! Maybe the video mode is the way to go, and I would be interested in the Windows Fractinct- I guess we've all gotten used to the keyboard commands, so it doesn't bother me that there is no mouse control yet. It would be convenient, but not necessary.

 

Yes, I have one laptop that will create images at a higher resolution, and this desktop. None of my newer machines will do it at work. I was excited to GET a new machine because I thought it would have the capacity. What is really necessary in the card that allows it to do so? Seems like if we knew that, we'd be one step up! I would order in a card if I was building out a machine, specifically so I could run Fractint!

 

Thanks for your help, and any more info you might have to impart!

About the only sure way that I can think of is to find someone
who owns a recent machine that has been shown to create
higher resolution fractals under Fractint. Then use Craig's list
or eBay to purchase a machine that has that exact video card in it.


I know that it is possible to put a second video card into a computer,
so in theory one could install an older card that supported the higher
resolution DOS video modes into a computer that has a video card
that does not support these video modes. Newer computers now
have different connectors to plug cards into, so the new machine
needs to have a connector compatible with the older video card
being installed into the new computer.

However, I do not know how to force 'switching' between these video
cards -- or if that is even possible in all cases.

One other problem with video 'cards' is that often, current computers
are manufactured with their video and audio chip sets on the main
system board for cost reasons. Being able to 'turn off' these factory
built-in functions and to get Windows to recognize a newly-installed
card to replace these functions takes detailed knowledge and
in some cases cannot be done at all.


I note that Sylvie Gallet says that Windows Vista appears to
not support the DOS version of Fractint. I pasted her message
below my signature.


Some good news is that there is a 'Fractint for Windows'
being worked on right now and a fairly stable beta is available.

It is intended to work on essentially any current computer's
video card and on any version of Windows. This is because it
writes to the video card using Windows drivers and graphics
modes, not DOS graphics modes.


The current beta (beta 5) is a first pass at creating a fully windowed
version of Fractint. The current user interface is simply the DOS
version text windows displayed in their current DOS form with
the image being calculated resizing the window as needed.
Keyboard commands work normally.

The current 'Fractint for Windows' does not
have mouse support, but movement of the zoom box
and cursors can be done using the arrow keys (with and
without the key being held down.)

Richard of the Fractint Development Team did a lot of work
to get the this functionality working under windows.


I myself have not used beta 5 'Fractint for Windows' very much,
but judging from the postings on [Fractint] from others, there are
people using it successfully. Further development is planned.


Richard's FractInt for Windows (Beta 5) 2007-02-18:

You can uninstall beta 4 or you can install beta 5
over top of beta 4.
If you install over top, beta 4 will be upgraded to beta 5.


The list of known existing bugs in beta 5 Fractint for
Windows is:

One other item. You say:

Are you familiar with Fractint's Disk 'Video' Modes?

These allow you to create high resolution images without
them being written to the video card. I use this feature
every day to create Jim Muth's Fractal of the Day at a
resolution of 1024 x 768 or 1280 x 1024 with DOS Fractint.

This feature completely gets around having to have a
video card show the image while it is being calculated.

My older computer with DOS Fractint will display images this large,
but only if they take up the entire screen. The images no longer
calculate or are corrupted if I try to shrink the image into
a window to allow me to look at email, etc.

So I simply use a Fractint Disk 'Video' Mode to calculate
my larger images. Since the window showing the image
calculation is simply a text status window I am able to
shrink it to a small window and read my email,
surf the web, etc. When Fractint's status window says,
"The image has been completed" I can maximize the window
to full screen and save the image and reload it into a
visible video mode in DOS Fractint on my older machine.

My newer machine would require me to view the large image
that I calculated using Disk Video Mode using a different image
viewing program. This is not too great a problem since you
can keep both the image viewing program and Fractint for
Windows open and running at the same time.

Fractint's documentation has more information about Disk
Video Modes. You can even define your own X and Y
resolutions of Disk Video Modes. I have done this and it
works well. Please ask me if you have any further questions
about Disk Video Mode.


Incidentally, I just tested adding a new set of X and Y
resolutions in a Disk Video Mode of Richard's beta 5
version of Fractint for Windows. I added 2048 x 1536
pixels. It created the image correctly and I viewed it
in an image viewing program.


What resolution do you create your images at in order to
print them? <---<<


Is this info of any use to you? <---<<

To: Liste Fractint

Hi All,
I just got a new computer with Windows Vista Home Premium and I'm
still in the process of customizing it and installing my favorite softs.

Bad news: Fractint for DOS won't run, all I get is an error msg saying
"This system does not support fullscreen mode. Choose 'Close'to
terminate the application."

Cheers,
- Sylvie

No, I didn't, Hal, and was sure hoping to! I have a
couple of old machines I hang onto just because I can
push the resolution, for printing. My brand new
machine at work, which is a REAL work horse,
cannot do it! I just don't know how to find out,
as you can imagine! As Fractint is one thing I LOVE
to work with, I'd really hate to invest in a machine
that can't do the job! Funny how newer isn't always
better!

Thanks! Hope somebody knows! I'll keep looking!

Kim
