from_hex_string()

color_t color_t::from_hex_string ( const std::string &  c )

static

Creates a new color_t object from a string variable in hex format.

Parameters

c	A string variable, in rrggbb hex format.

Returns

A new color_t object.

Exceptions

std::invalid_argument

if the string is not correctly formatted

from_rgb_string()

color_t color_t::from_rgb_string ( const std::string &  c )

static

Creates a new opaque color_t object from a string variable in "R,G,B" format.

An empty string results in white. Otherwise, omitting components is an error.

Parameters

c	A string variable, in "R,G,B" format.

Returns

A new color_t object.

Exceptions

from_rgba_bytes()

color_t color_t::from_rgba_bytes ( uint32_t  c )

static

Creates a new color_t object from a uint32_t variable.

Parameters

c	A uint32_t variable, in RGBA format.

Returns

A new color_t object.

Definition at line 78 of file color.cpp.

from_rgba_string()

color_t color_t::from_rgba_string ( const std::string &  c )

static

Creates a new color_t object from a string variable in "R,G,B,A" format.

An empty string results in white. Otherwise, omitting components other than alpha is an error.

Parameters

c	A string variable, in "R,G,B,A" format.

Returns

A new color_t object.

Exceptions
