Шаблон:RGBtoHSV.S

Ҳуҷҷатгузорӣ

This template computes the HSV saturation 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.S|r|g|b}}

The range of the three parameters is [0..255] ; they can be any numeric expressions.

{{subst:RGBtoHSV.S|r|g|b|subst=subst:}}

To substitute the template invocation by the compute value when saving an article Wiki source.

Algorithm used

C = max(r, g, b) - min(r, g, b)

V = max(r, g, b)

if V = 0 then

S = 0;

else

S = C / V

return S round 3;

Examples

"{{RGBtoHSV.S|0|0|0}}" returns "0".
"{{RGBtoHSV.S|255|255|255}}" returns "0".
"{{RGBtoHSV.S|255|0|0}}" returns "1".
"{{RGBtoHSV.S|255|1|0}}" returns "1".
"{{RGBtoHSV.S|255|127.5|0}}" returns "1".
"{{RGBtoHSV.S|255|255|0}}" returns "1".
"{{RGBtoHSV.S|127.5|255|0}}" returns "1".
"{{RGBtoHSV.S|0|255|0}}" returns "1".
"{{RGBtoHSV.S|0|255|127.5}}" returns "1".
"{{RGBtoHSV.S|0|255|255}}" returns "1".
"{{RGBtoHSV.S|0|127.5|255}}" returns "1".
"{{RGBtoHSV.S|0|0|255}}" returns "1".
"{{RGBtoHSV.S|127.5|0|255}}" returns "1".
"{{RGBtoHSV.S|255|0|255}}" returns "1".
"{{RGBtoHSV.S|255|0|127.5}}" returns "1".
"{{RGBtoHSV.S|255|0|1}}" returns "1".
example for "sandybrown" = "#F4A460" = "rgb(244, 164, 96)" = "hsl(27.6, 0.871, 0.667)"

"{{RGBtoHSV.S|244|164|96}}" returns "0.607".

same example using subst

"{{subst:RGBtoHSV.S|244|164|96|subst=subst:}}" returns "0.607".
