Incredible. HSL tool work fine now with 16 bits images. Great job Marcel.
But The other part witch used HSL modifier algorithm is Image Editor Black &
White converter. Any B&W converter options are broken :
- Sepia tone.
- Brown Tone.
- Cold Tone.
- Selenium Tone.
- Platinium Tone.
I think that the B&W implementations must be adapted to your patch...
