This template computes the HSV value in [0..1] from a color specified in the sRGB color space. The returned value is rounded to three decimals (which preserves the precision of RGB colors whose components are specified in the standard range [0..255]).
- Syntax
- {{RGBtoHSV.V|r|g|b}}
- The range of the three parameters is [0..255] ; they can be any numeric expressions.
- {{subst:RGBtoHSV.V|r|g|b|subst=subst:}}
- To substitute the template invocation by the computed value when saving an article Wiki source.
- Algorithm used
- V = max(r, g, b) / 255
- return V round 3;
- Examples
- "{{RGBtoHSV.V|0|0|0}}" returns "0".
- "{{RGBtoHSV.V|255|255|255}}" returns "1".
- "{{RGBtoHSV.V|255|0|0}}" returns "1".
- "{{RGBtoHSV.V|255|1|0}}" returns "1".
- "{{RGBtoHSV.V|255|127.5|0}}" returns "1".
- "{{RGBtoHSV.V|255|255|0}}" returns "1".
- "{{RGBtoHSV.V|127.5|255|0}}" returns "1".
- "{{RGBtoHSV.V|0|255|0}}" returns "1".
- "{{RGBtoHSV.V|0|255|127.5}}" returns "1".
- "{{RGBtoHSV.V|0|255|255}}" returns "1".
- "{{RGBtoHSV.V|0|127.5|255}}" returns "1".
- "{{RGBtoHSV.V|0|0|255}}" returns "1".
- "{{RGBtoHSV.V|127.5|0|255}}" returns "1".
- "{{RGBtoHSV.V|255|0|255}}" returns "1".
- "{{RGBtoHSV.V|255|0|127.5}}" returns "1".
- "{{RGBtoHSV.V|255|0|1}}" returns "1".
- example for "sandybrown" = "#F4A460" = "rgb(244, 164, 96)" = "hsl(27.6, 0.871, 0.667)"
- "{{RGBtoHSV.V|244|164|96}}" returns "0.957".
- same example using subst
- "{{subst:RGBtoHSV.V|244|164|96|subst=subst:}}" returns "0.957".
