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 |
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.
This structure is used by both the L_HSVtoRGB and L_RGBtoHSV functions.
