Detailed Description

A basic RGBA type.

This both represents a SWF RGBA record and is a basic Gnash type for color values.

Constructor & Destructor Documentation

rgba() [1/2]

constexpr gnash::rgba::rgba ( )

inline

Construct default RGBA value.

Default value is 0xffffffff (solid white).

rgba() [2/2]

gnash::rgba::rgba ( std::uint8_t  r, std::uint8_t  g, std::uint8_t  b, std::uint8_t  a  )

inline

Construct an RGBA with the provided values.

Parameters

r	Red
g	Green
b	Blue
a	Alpha (transparency)

operator!=()

bool gnash::rgba::operator!= ( const rgba &  o ) const

inline

References gnash::key::o.

operator==()

bool gnash::rgba::operator== ( const rgba &  o ) const

inline

parseRGB()

void gnash::rgba::parseRGB ( std::uint32_t  rgbCol )

inline

Parse a 32-bit unsigned integer as three packed R,G,B bytes.

Alpha will be untouched. Blue is the least significant byte.

This function is meant to be used to parse ActionScript colors in numeric format.

Referenced by gnash::colorFromHexString(), gnash::registerMovieClipNative(), gnash::registerTextFieldNative(), gnash::StaticText::setSelectionColor(), and gnash::textformat_class_init().

toRGB()

std::uint32_t gnash::rgba::toRGB ( ) const

inline

Return a 32-bit unsigned integer as four packed R,G,B bytes.

Blue is the least significant byte. The most significant (alpha) byte is unused.

This function is meant to be used to output ActionScript colors in numeric format.

Referenced by gnash::registerTextFieldNative().

toRGBA()

std::uint32_t gnash::rgba::toRGBA ( ) const

inline

Return a 32-bit unsigned integer as four packed A,R,G,B bytes.

Blue is the least significant byte.

This function is meant to be used to output ActionScript colors in numeric format.
