Public Member Functions |
| Color () |
| The default constructor does not initialize the color to any value.
|
| Color (unsigned argb) |
| Conversion constructor for literals of the form 0xaarrggbb.
|
| Color (Channel red, Channel green, Channel blue) |
| Color (Channel alpha, Channel red, Channel green, Channel blue) |
Channel | red () const |
Channel | green () const |
Channel | blue () const |
Channel | alpha () const |
void | setRed (Channel value) |
void | setGreen (Channel value) |
void | setBlue (Channel value) |
void | setAlpha (Channel value) |
double | hue () const |
| Returns the hue of the color, in the usual range of 0..360.
|
void | setHue (double h) |
| Changes the current color so hue() will return h.
|
double | saturation () const |
| Returns the saturation of the color, in the range of 0..1.
|
void | setSaturation (double s) |
| Changes the current color so saturation() will return s.
|
double | value () const |
| Returns the value (brightness) of the color, in the range of 0..1.
|
void | setValue (double v) |
| Changes the current color so value() will return v.
|
std::tr1::uint32_t | argb () const |
| Returns the color in 0xaarrggbb representation.
|
std::tr1::uint32_t | bgr () const |
| Returns the color in 0x00bbggrr representation. Useful for Win32 programming.
|
std::tr1::uint32_t | abgr () const |
| Returns the color in 0xaabbggrr representation.
|
std::tr1::uint32_t | gl () const |
| Returns the internal representation of the color (RGBA in memory).
|

Represents an RGBA color value with 8 bits for each channel.
Can be implicitly constructed from literals of the form 0xaarrggbb. Has fast value semantics. The four-byte layout in memory is RGBA. On Big-Endian machines the unsigned int interpretation is 0xrrggbbaa, on Little-Endian machines it is 0xaabbggrr.
