Comments

pHSVREF is a pointer to an HSVREF structure.

The HSV value is the Hue ,Saturation, Value color space. Traditionally, hue ranges from 0 to 359. However, the hue component of the HSVREF is represented by an unsigned byte. Therefore, the range of 0 to 359 is remapped to a range of 0..255. For example,

Color	Hue(0..359)	Hue(0..255)
Red	0	0
Green	120	85
Blue	240	170
