Public Member Functions | |
| PixelRGB () noexcept | |
| Creates a pixel without defining its colour. | |
| ~PixelRGB () noexcept | |
| PixelRGB (const uint32 argb) noexcept | |
| Creates a pixel from a 32-bit argb value. | |
| forcedinline uint32 | getARGB () const noexcept |

| template<class Pixel > | |
| forcedinline void | blend (const Pixel &src) noexcept |
| Blends another pixel onto this one. | |
| forcedinline void | blend (const PixelRGB &src) noexcept |
| template<class Pixel > | |
| forcedinline void | blend (const Pixel &src, uint32 extraAlpha) noexcept |
| Blends another pixel onto this one, applying an extra multiplier to its opacity. | |
| template<class Pixel > | |
| forcedinline void | tween (const Pixel &src, const uint32 amount) noexcept |
| Blends another pixel with this one, creating a colour that is somewhere between the two, as specified by the amount. | |
| template<class Pixel > | |
| forcedinline void | set (const Pixel &src) noexcept |
| Copies another pixel colour over this one. | |
| forcedinline void | setAlpha (const uint8) noexcept |
| This method is included for compatibility with the PixelARGB class. | |
| forcedinline void | multiplyAlpha (int) noexcept |
| Multiplies the colour's alpha value with another one. | |
| forcedinline void | multiplyAlpha (float) noexcept |
| Multiplies the colour's alpha value with another one. | |
| void | setARGB (const uint8, const uint8 r_, const uint8 g_, const uint8 b_) noexcept |
| Sets the pixel's colour from individual components. | |
| forcedinline void | premultiply () noexcept |
| Premultiplies the pixel's RGB values by its alpha. | |
| forcedinline void | unpremultiply () noexcept |
| Unpremultiplies the pixel's RGB values. | |
| forcedinline void | desaturate () noexcept |
Represents a 24-bit RGB pixel, and can perform compositing operations on it.
This is used internally by the imaging classes.
| anonymous enum |
Creates a pixel without defining its colour.
| PixelRGB::PixelRGB | ( | const uint32 | argb | ) |
Creates a pixel from a 32-bit argb value.
(The argb format is that used by PixelARGB)
| forcedinline uint32 PixelRGB::getARGB | ( | ) | const |
| forcedinline uint32 PixelRGB::getRB | ( | ) | const |
| forcedinline uint32 PixelRGB::getAG | ( | ) | const |
| forcedinline uint8 PixelRGB::getAlpha | ( | ) | const |
| forcedinline uint8 PixelRGB::getRed | ( | ) | const |
| forcedinline uint8 PixelRGB::getGreen | ( | ) | const |
| forcedinline uint8 PixelRGB::getBlue | ( | ) | const |
| forcedinline void PixelRGB::blend | ( | const Pixel & | src | ) |
Blends another pixel onto this one.
This takes into account the opacity of the pixel being overlaid, and blends it accordingly.
| forcedinline void PixelRGB::blend | ( | const PixelRGB & | src | ) |
| forcedinline void PixelRGB::blend | ( | const Pixel & | src, |
| uint32 | extraAlpha | ||
| ) |
Blends another pixel onto this one, applying an extra multiplier to its opacity.
The opacity of the pixel being overlaid is scaled by the extraAlpha factor before being used, so this can blend semi-transparently from a PixelRGB argument.
| forcedinline void PixelRGB::tween | ( | const Pixel & | src, |
| const uint32 | amount | ||
| ) |
Blends another pixel with this one, creating a colour that is somewhere between the two, as specified by the amount.
| forcedinline void PixelRGB::set | ( | const Pixel & | src | ) |
Copies another pixel colour over this one.
This doesn't blend it - this colour is simply replaced by the other one. Because PixelRGB has no alpha channel, any alpha value in the source pixel is thrown away.
| forcedinline void PixelRGB::setAlpha | ( | const uint8 | ) |
This method is included for compatibility with the PixelARGB class.
| forcedinline void PixelRGB::multiplyAlpha | ( | int | ) |
Multiplies the colour's alpha value with another one.
| forcedinline void PixelRGB::multiplyAlpha | ( | float | ) |
Multiplies the colour's alpha value with another one.
| void PixelRGB::setARGB | ( | const uint8 | , |
| const uint8 | r_, | ||
| const uint8 | g_, | ||
| const uint8 | b_ | ||
| ) |
Sets the pixel's colour from individual components.
| forcedinline void PixelRGB::premultiply | ( | ) |
Premultiplies the pixel's RGB values by its alpha.
| forcedinline void PixelRGB::unpremultiply | ( | ) |
Unpremultiplies the pixel's RGB values.
| forcedinline void PixelRGB::desaturate | ( | ) |
