plhlsrgb(h, l, s, p_r, p_g, p_b)

Convert HLS color coordinates to RGB.

Redacted form: General: plhlsrgb(h, l, s, p_r, p_g, p_b)

This function is used in example 2.

h (PLFLT(3plplot), input)

Hue in degrees (0.0-360.0) on the color cylinder.

l (PLFLT(3plplot), input)

Lightness expressed as a fraction (0.0-1.0) of the axis of the color cylinder.

s (PLFLT(3plplot), input)

Saturation expressed as a fraction (0.0-1.0) of the radius of the color cylinder.

p_r (PLFLT_NC_SCALAR(3plplot), output)

Returned value of the red intensity (0.0-1.0) of the color.

p_g (PLFLT_NC_SCALAR(3plplot), output)

Returned value of the green intensity (0.0-1.0) of the color.

p_b (PLFLT_NC_SCALAR(3plplot), output)

Returned value of the blue intensity (0.0-1.0) of the color.
