I tried to load 30GB image to Krita, it crashes. Gimp handles it pretty well.

Hmmmm, how much ram did the PC have that his happened on?

Did you mean MB rather than GB?

Kind of wondering what kind of image would be 30GB... :)

Thanks. Found info on that file format:

* https://openslide.org/formats/aperio/

* https://web.archive.org/web/20120420105738/http://www.aperio...

Pages 14 onward give the info. Seems like it's a variation of TIFF, in tiled format.

Main tile (image) size is 120k x 80k. That's huge!

29GB when saved uncompressed. I'd hope most applications would use the optional compression features. :)

This was 360 degree mosaic, about 100kX100k
