The the Blue Earth Bathymetry image (public domain) from http://www.shadedrelief.com/blue-earth/ doesn't load right. This is how it should look like: https://gitlab.gnome.org/GNOME/gimp/uploads/a2e4e7ca483354877c4a8b1cf9f84ecf/image.png This is how it looks in Krita 4.3.0 (I used the GIMP screenshot, but it looks the same in Krita): https://gitlab.gnome.org/GNOME/gimp/uploads/43578396382c5471b4e4bf1f4382f0a8/image.png Miha Kadunc on Twitter wrote: "This happens because negative numbers are at the top end of the range when int16 is interpreted as uint16" https://twitter.com/miha_kadunc/status/1275091809493008385 Direct download: http://www.shadedrelief.com/blue-earth/Blue-Earth-Bathymetry.zip
Yeah. Krita reads and knows it's int, but then ignores it completely. Btw is there any place to get this file but cropped/much smaller? It eats lots of RAM and time to open it, and of course cropping in Krita or Gimp (since I have an older version) or Darktable destroys the uniqueness of the file, since it's converted from ints to uints.
