## Constructor & Destructor Documentation

## ◆ SolidPattern()

Cairo::SolidPattern::SolidPattern | ( | cairo_pattern_t * | cobject,
|  | bool | has_reference = false )
| explicit

Create a C++ wrapper for the C instance.

Parameters

  cobject | The C instance.
  has_reference | Whether we already have a reference. Otherwise, the constructor will take an extra reference.

## ◆ ~SolidPattern()

Cairo::SolidPattern::~SolidPattern | ( |  | ) |
| override

## Member Function Documentation

## ◆ create_rgb()

RefPtr< SolidPattern > Cairo::SolidPattern::create_rgb | ( | double | red,
|  | double | green,
|  | double | blue )
| static

Creates a new Cairo::Pattern corresponding to an opaque color.

The color components are floating point numbers in the range 0 to 1. If the values passed in are outside that range, they will be clamped.

Parameters

  red | red component of the color
  green | green component of the color
  blue | blue component of the color

## ◆ create_rgba()

RefPtr< SolidPattern > Cairo::SolidPattern::create_rgba | ( | double | red,
|  | double | green,
|  | double | blue,
|  | double | alpha )
| static

Creates a new Cairo::Pattern corresponding to a translucent color.

The color components are floating point numbers in the range 0 to 1. If the values passed in are outside that range, they will be clamped.

Parameters

  red | red component of the color
  green | green component of the color
  blue | blue component of the color
  alpha | alpha component of the color

## ◆ get_rgba()

void Cairo::SolidPattern::get_rgba | ( | double & | red,
|  | double & | green,
|  | double & | blue,
|  | double & | alpha ) const

Gets the solid color for a solid color pattern.

Parameters

  red | return value for red component of color
  green | return value for green component of color
  blue | return value for blue component of color
  alpha | return value for alpha component of color
