[Qgis-developer] Raster saturation issue

[Nyall Dawson]

>> On testing saturation today, I did notice a potential bug with that setting. For my test raster, I set the saturation to 1 and the difference between that setting and 0 was quite large. If I move to 2, 3, 4, and so on, the differences are very small and incremental.
>>
>> I'm wondering why the leap in saturation from 0 to 1? Is something incorrect in the algorithm calculating saturation? It seems as the values between 0 and 1 need to be handled to make the 0 to 1 change as incrementally small as the 1 to 2.

Actually - I can replicate it here. Don't worry about attaching a raster.
