Dithering when changing image precision
Operating System: All
Description of the feature
About dithering when changing the image precision
- Dithering would also be useful when promoting from 8 to 16 bit integer (if doable) or 16-bit precision.
- Currently the only existing control is with the automatic promotion to 32-bit on import, so it gets very complicated to have both dithered and non-dithered images in the same session
- I assume that the image can be dithered manually by adding some low-level noise, but nothing says that I will hit exactly the same kind of result as the automatic dithering done by Gimp
So, we need either:
- A
Dither image
option in the precision change dialog (next to theLinear/Non-linear
choice)(a minima in the change to 32-bit FP) - Some
Filters > Noise > Dither image
(which unfortunately collides withColor > Dither
that does quite the opposite)
