Floating point numbers are less precise than integers. In GIMP and GEGL, 32-bit float linear RGB is common so if you use that there will be less conversions between different formats. _______________________________________________ gimp-user-list mailing list List address: [email protected] List membership: https://mail.gnome.org/mailman/listinfo/gimp-user-list List archives: https://mail.gnome.org/archives/gimp-user-list
