Function Documentation

void HSV2RGB (  Uint16  hin, Uint8  sin, Uint8  vin, Uint8 *  rout, Uint8 *  gout, Uint8 *  bout )

Converts h/s/v values of a color to r/g/b values of the color. This function converts h/s/v values of a color in HSV color space to r/g/b values of the color in RGB space. Parameters: hin  The h value of the HSV color space to be converted, the range is between 0 to 359. sin  The s value of the HSV color space to be converted, the range is between 0 to 255. vin  The v value of the HSV color space to be converted, the range is between 0 to 255. rout  The pointer to Uint8, returns the red value of the RGB color space. gout  The pointer to Uint8, returns the green value of the RGB color space. bout  The pointer to Uint8, returns the bout value of the RGB color space.
