Template:RGBtoHSV.V

Template documentation[view] [edit] [history] [purge]

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".
