XmtHSLToRGB(3) Library Functions Manual XmtHSLToRGB(3) NAME XmtHSLToRGB(), XmtRGBToHSL() - convert between the HSL and RGB color spaces. SYNOPSIS #include <Xmt/Color.h> void XmtHSLToRGB(unsigned h, unsigned s, unsigned l, unsigned *r, unsigned *g, unsigned *b) void XmtRGBToHSL(unsigned r, unsigned g, unsigned b, unsigned *h, unsigned *s, unsigned *l) ARGUMENTS h The Hue of the color. This is an input to XmtHSLToRGB() and an out- put from XmtRGBToHSL(). s The Saturation of the color. This is an input to XmtHSLToRGB() and an output from XmtRGBToHSL(). l The Lightness of the color. This is an input to XmtHSLToRGB() and an output from XmtRGBToHSL(). r The Red component of the color. This is an input to XmtRGBToHSL() and an output from XmtHSLToRGB(). g The Green component of the color. This is an input to XmtRGBToHSL() and an output from XmtHSLToRGB(). b The Blue component of the color. This is an input to XmtRGBToHSL() and an output from XmtHSLToRGB(). DESCRIPTION XmtHSLToRGB() converts a color specified in the HSL color space to the equivalent color in the RGB color space. XmtRGBToHSL() performs the oppo- site conversion-from the RGB color space to the HSL color space. In X, the r, g, and b components of an RGB color vary between 0 and 65535. As implemented by Xmt, the Hue of a HSL color is an angle between 0 and 359, and the Saturation and Lightness of a color vary between 0 and 100. Note that the h, s, and l arguments are unsigned, not float or double. See Chapter 6, Using Color, for more information on the HSL color space.
