Filter Reference

Color Filters

These are not provided in the default filters. They are available in the code, but they are not loaded by default. There is an extension method to load them.

C#

TemplateOptions.Default.Filters.WithColorFilters();

MethodColorFilters.ToRgb

color_to_hex

MethodColorFilters.ToHex

color_to_hsl

MethodColorFilters.ToHsl

color_extract

MethodColorFilters.ColorExtract

color_modify

MethodColorFilters.ColorModify

color_brightness

MethodColorFilters.CalculateBrightness

color_saturate

MethodColorFilters.ColorSaturate

color_desaturate

MethodColorFilters.ColorDesaturate

color_lighten

MethodColorFilters.ColorLighten
