touchgfx::Color class

@class Color Color.hpp touchgfx/Color.hpp Contains functionality for color conversion. Contains functionality for color conversion.

Syntax

Methods

getGreenColor()

@fn static inline uint8_t Color::getGreenColor(colortype color) Gets the green color part of a color. Gets the green color part of a color. As this function must work for all color depths, it can be somewhat slow if used in speed critical sections. Consider finding the color in another way, if possible. Read more...

getBlueColor()

@fn static inline uint8_t Color::getBlueColor(colortype color) Gets the blue color part of a color. Gets the blue color part of a color. As this function must work for all color depths, it can be somewhat slow if used in speed critical sections. Consider finding the color in another way, if possible. Read more...

getColorFrom24BitRGB()

@fn static colortype Color::getColorFrom24BitRGB(uint8_t red, uint8_t green, uint8_t blue); Generates a color representation to be used on the LCD, based on 24 bit RGB values. Depending on your chosen color bit depth, the color will be interpreted internally as either a 16 bit or 24 bit color value. Generates a color representation to be used on the LCD, based on 24 bit RGB values. Depending on your chosen color bit depth, the color will be interpreted internally as either a 16 bit or 24 bit color value. This function can be safely used regardless of whether your application is configured for 16 or 24 bit colors. Read more...

getRedColor()

@fn static inline uint8_t Color::getRedColor(colortype color) Gets the red color part of a color. Gets the red color part of a color. As this function must work for all color depths, it can be somewhat slow if used in speed critical sections. Consider finding the color in another way, if possible. Read more...
