@microsoft/fast-colors > centeredRescale
centeredRescale() function
Takes an input array of colors and extrapolates them to a larger palette. The mapping first takes the input array and extrapolates between each color so that they are separated by spacing-1 slots. Then it adds to either end enough new colors to make up the desired targetSize. All output color slots between the defined stops are interpolated.
Signature:export declare function centeredRescale(input: ColorRGBA64[], config?: CenteredRescaleConfig): ColorRGBA64[];
