What are minimum and maximum values for filters?

[rupinderjeet]

I know: -1f <= brightness <= 1f 0f <= contrast <= 4f

I want to know same about Saturation, Pixelation and Sharpen? Do they have any boundries?

If you could add such values for other filters as well, it would help me a lot.

Thank you for your work, Masayuki.

Have the seekbar progress as 50 for brightness, Saturation, Sharpen for video neutral position.
