Color¶
- class
A RGB color representation, generic for display devices.
This class implements a 16-bit RGB 5-6-5 color model. It support methods for calculating color blendings and more.
The class definition also define a set of global constant predefined colors, like white, red, green, blue and black. Further, it includes a set of the FlatUI colors that Mono uses:
- Clouds
- WetAsphalt
- Concrete
- Silver
- Asbestos
- BelizeHole
- MidnightBlue
- Alizarin
- Turquoise
- Emerald
Public Functions
-
Color::Color()¶ Construct a black color.
-
Color::Color(const int col)¶ Construct a color from an existing 5-6-5 encoded value.
This constructor takes a an integer an casts it to a 5-6-5 RGB color, from from the integers LSB’s.
- Parameters
col-The 5-6-5 RGB color value
-
Color::Color(uint8_t R, uint8_t G, uint8_t B)¶ Construct a color from individual RGB components.
You provide 8-bit RGB components to create the color.
- Parameters
R-The red component, 0 to 255
G-The red component, 0 to 255
B-The red component, 0 to 255
-
uint8_t
Color::Red()¶
const Return 8-bit red color component
-
uint8_t
Color::Green()¶
const Return 8-bit green color component
-
uint8_t
Color::Blue()¶
const Return 8-bit blue color component
-
Color
Color::scale(uint8_t factor)¶
const Misc.
Multiply each RGB channel by a factor from 0-255
- Return
- the scaled color
-
Color
Color::blendMultiply(Color other)¶
const Return the product of two colors
- Return
- the multiply blended color
-
Color
Color::blendAdditive(Color other)¶
const Add this color with another
-
Color
Color::invert()¶
const Return the inverse
-
Color
Color::alphaBlend(uint8_t intensity, Color const &other)¶
const Blend this color with another using a provided intensity.
Alpha blending is done when you need to combine two colors, say you wish to realize a gradient. If you blend black and white the intensity will define all the grayscales in between.
Use this method to realize an alpha channel that controls how transparent a certain color is. The alpha channel controls the intensity, and you must provide the color that lies behind the alpha blended color.
- Return
- The new blended color
- Parameters
intensity-The intensity of this color, 0 to 255.
other-The color to blend with
