END OF AN ERA, FRACTALFORUMS.COM IS CONTINUED ON FRACTALFORUMS.ORG

What is the maximum render size that kalles fraktaler should be capable of? 16000×16000 works, 25600×19200 doesn't, but the program doesn't crash, it just looks like nothing is happening.

Edit: "Nothing happening" turns out to be "no visual updates in the program", at least some of the time. CPU usage indicates the rendering does take place.

Exporting JPEG fails when the resolution is more than 2^29, the same limit as for mandel machine. However, the JPEG I was trying to save was 24000×24000 so it makes me wonder if the kfb map would have been good. If I could split the map into pieces, make images of those, and assemble the puzzle in photoshop, after partial anti-aliasing if needed, that would be great. Extremely high resolutions are mandatory to make a render look good even after resizing to a lower resolution so I want to push the limit as much as I can.

Something else that I consider very important, less important however, is no lossy compression anywhere in the process. It surprises me that kalles fraktaler can only save JPEG images. Why no BMP or PNG? Lossy compression, if used, should only be used as the final step in the process.

Edit2: Resolutions higher than 2^29 can cause crashes while rendering. The result is unreliable.

It wasn't. I checked it.

Yes, thats the way I have made some of my larger renders. The largest one is about 6400*39600 but larger images are possible.

As for standard rendering 16000*9000 is the largest size I have been able to render as a single image.

These two combined with some patience could make some huge images.

That's very useful. Thanks!
