## Constructor & Destructor Documentation

Cairo::RadialGradient::RadialGradient | ( | double | cx0,
|  | double | cy0,
|  | double | radius0,
|  | double | cx1,
|  | double | cy1,
|  | double | radius1 |
| ) |  |  | `[protected]`

Cairo::RadialGradient::RadialGradient | ( | cairo_pattern_t * | cobject,
|  | bool | has_reference = `false` |
| ) |  |  | `[explicit]`

Create a C++ wrapper for the C instance.

This C++ instance should then be given to a RefPtr.

Parameters:

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

virtual Cairo::RadialGradient::~RadialGradient | ( |  | ) | `[virtual]`

## Member Function Documentation

static RefPtr<RadialGradient> Cairo::RadialGradient::create | ( | double | cx0,
|  | double | cy0,
|  | double | radius0,
|  | double | cx1,
|  | double | cy1,
|  | double | radius1 |
| ) |  |  | `[static]`

void Cairo::RadialGradient::get_radial_circles | ( | double & | x0,
|  | double & | y0,
|  | double & | r0,
|  | double & | x1,
|  | double & | y1,
|  | double & | r1 |
| ) |  |  | const

Parameters:

  | x0 | return value for the x coordinate of the center of the first (inner) circle
  | y0 | return value for the y coordinate of the center of the first (inner) circle
  | r0 | return value for the radius of the first (inner) circle
  | x1 | return value for the x coordinate of the center of the second (outer) circle
  | y1 | return value for the y coordinate of the center of the second (outer) circle
  | r1 | return value for the radius of the second (outer) circle

Gets the gradient endpoint circles for a radial gradient, each specified as a center coordinate and a radius.
