L_LTDIS_API HSVREF L_RGBtoHSV(crColor)
The RGB input value.
An HSVREF that contains the Hue, Saturation, Value equivalent of the specified RGB value.
This function does not support signed data images. It returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image is passed to this function.
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.
Win32, x64, Linux.
For an example, refer to L_RemapBitmapHue.
