Comments
pHSVREF is a pointer to an HSVREF structure.
The HSV value is the Hue, Saturation and 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 |
Saturation ranges from 0 to 255 where 0 means the highest amount of white and 255 means no white.
Value ranges from 0 to 255 where 0 means highest amount of black and 255 means no black.
