How to use it
Parameter Range
All inputs and outputs are three floats in the range [0.0...1.0] (with the exception of I and Q, which covers a slightly larger range also with the exception of R, G and B, which range from 0 to 255 also with the exception of H, which range from 0 to 360).
range of each parameter
R, G, B : 0 ~ 255
I, Q : -1 ~ 1.X
H : 0 ~ 360
Y, S, V, L : 0 ~ 1
Examples
- RGB to YIQ
y, i, q := colorsys.Rgb2Yiq(r, g, b)
- YIQ to RGB
r, g, b := colorsys.Yiq2Rgb(y, i, q)
- RGB to HLS
h, l, s := colorsys.Rgb2Hls(r, g, b)
- HLS to RGB
r, g, b := colorsys.Hls2Rgb(h, l, s)
- RGB to HSV
h, s, v := colorsys.Rgb2Hsv(r, g, b)
- HSV to RGB
r, g, b := colorsys.Hsv2Rgb(h, s, v)
- Yiq to Hls
h, l, s := colorsys.Yiq2Hls(y, i, q)
- YIQ to HSV
h, s, v := colorsys.Yiq2Hsv(y, i, q)
- HLS to YIQ
y, i, q := colorsys.Hls2Yiq(h, l, s)
- HLS to HSV
h, s, v := colorsys.Hls2Hsv(h, l, s)
- HSV to YIQ
y, i, q := colorsys.Hsv2Yiq(h, s, v)
- HSV to HLS
h, l, s := colorsys.Hsv2Hls(h, s, v)
