You're welcome! I have a 780MB 48-bit color TIFF panorama I generated a few years ago. GIMP opened it very slowly on my old 32-bit Linux Toshiba laptop with only 2GB RAM. (Including converting it to 24-bit color as it was opening the image.) But it did open. On my present 16GB i7 laptop, it opens much faster. :) When I have a real budget for my creative work, I hope to get something with many more cores, more clock speed, and maybe 4x as much memory. And a 4K display. <drool> I've noticed that opening GIF images under Linux is much slower than opening JPGs, TIFs or PNGs of comparable dimensions. So maybe there's something about the format that slows things down. I've never opened GIFs of comparable sizes on a Windows system. In fact, last time I recall opening a GIF on a Windows machine was back in the days of Windows 98SE. That was on a dual-boot OS/2 setup. Interesting, DOS Fractint under W98 would hang the machine. Under OS/2, DOS Fractint ran with no problems. Eagerly awaiting the Linux SDL version. Although XFractint is pretty good. On 10/02/2017 10:13 AM, Harold Lane wrote:
Maybe try The GIMP... I had Gimp ver 2.8.16 on my computer, but forgot to try it. I very seldom have need for it.
Gimp opened the 53510 x 40132 (~1/3 /GB) .gif image just fine. First it used the hard drive, then it used ~90% of my 16 GB of RAM, and finally seemed to use the hard drive again. As it opened, it automatically scaled the image to fit a copy into the size of the default window it opened (at 2.22% zoom), and correctly labeled the X and Y axes in 5,000 pixel increments.
Believe it or not, at a zoom of 1:1, it scrolls smoothly, showing the expected image. The image must all be in RAM.
If anyone else wants to try the experiment of viewing or processing an image of this size, I could try putting it onto my server...
Thanks for suggesting Gimp, David!

Maybe try The GIMP or my favorite Windows image utility Irfanview? I have viewed large GIF images on Linux using GIMP.

Jonathan, Using your new 2017-10-01 version of your SDL2 Fractint and your disk video mode I calculated a humdrum M-set fractal at your: "53510, 40132, 256, Largest .75 aspect ratio" which, when it finally finished, weighs in at over 300 MB.
However, I couldn't immediately find any program on my Win 10 computer that could open it, including PhotoShop ver 12.1 X64 and Adobe Fireworks CS5.
I restarted your SDL2 Fractint and it did open and read the image in, showing this screen: http://tinyurl.com/Restore-completed or: http://www.emarketingiseasy.com/Fractint/Restore_completed.jpg
The fractal in the above image looks like it might be the default Fractint startup M-set with the color map of the restored image.
Immediately after the giant restore, I changed the image resolution and calculated a 640x480 version of the restored image. It looks like the correct location and color map of the original image: http://tinyurl.com/640x480-calcd-aftr-big-restore or: http://www.emarketingiseasy.com/Fractint/640x480-calcd-after-big-restore.jp g
which pretty well matches the original image: http://tinyurl.com/Fractint-writing-line-n or: http://www.emarketingiseasy.com/Fractint/writing_line_%7Bn%7D.jpg
I enjoyed using <Enter> and <,> and <.> in <c> Color Map mode, although I did once crash SDL2 Fractint using those keys. Unfortunately, I'm not able to reproduce the circumstances and report them to you. It's possible that I may have given the program a keystroke it was not expecting to have to handle in whatever state/mode the Color Map code was in at the time...

Folks,
I've updated the SDL port to support color cycling. The color editor still doesn't work.
I added disk video modes for the largest sizes supported to the end of fractint.cfg. If you want to be able to run them more than once before having to restart Fractint, assign them to key codes (like AF6 & AF7). I am working on fixing this.
