| Header | #include "nativeui/gfx/color.h" |
| Namespace | namespace nu |
| Type | class |
This class should be copied by value under most cases, since the underlying
type is a simple uint32_t.
Constructors
Color()
Create a black color.
Color(const std::string& hex)
Create color from hex string, like "#A123", "#123", "#AA112233",
"#112233".
Parameters
const std::string&hex
Color(uint32_t value)
Create color from raw ARGB value.
Parameters
uint32_tvalue
Color(unsigned a, unsigned r, unsigned g, unsigned b)
Create an ARGB color.
Parameters
unsigneda - 8-bit alpha channel value.unsignedr - 8-bit red channel value.unsignedg - 8-bit green channel value.unsignedb - 8-bit blue channel value.
Color(unsigned r, unsigned g, unsigned b)
Create an opaque RGB color.
Parameters
unsignedr - 8-bit red channel value.unsignedg - 8-bit green channel value.unsignedb - 8-bit blue channel value.
