Description

Clamp restricts an integer value to fit within a specified range.

• The single-parameter overload Clamp(Value) clamps to byte channel range [0..255].
• The two-parameter overload Clamp(Value, Max) clamps to [0..Max].
• The three-parameter overload Clamp(Value, Min, Max) clamps to [Min..Max].
