Parameters

entries  Color32

The color entries to be stored by this Palette instance.

backColor  Color32

If entries does not contain partially transparent colors, then specifies the background color for lookup operations (GetNearestColor, GetNearestColorIndex). When a lookup is performed with a color, whose Color32.A field is equal to or greater than alphaThreshold, and there is no exact match among the entries, then the color to be found will be blended with this color before performing the lookup. The Color32.A field of the background color is ignored.

alphaThreshold  Byte

If there is at least one completely transparent color among entries, then specifies a threshold value for the Color32.A field, under which lookup operations will return the first transparent color (GetNearestColor) or the index of the first transparent color (GetNearestColorIndex).

customGetNearestColorIndex  FuncColor32, Int32

A delegate specifying an optional custom lookup logic to obtain an index from entries by a Color32 instance. If specified, it must be thread-safe, and it is expected to be fast. The results returned by the specified delegate are not cached. If , then GetNearestColor and GetNearestColorIndex methods will perform a sequential lookup by using a default logic and results will be cached.
