## Constructor & Destructor Documentation

Cairo::LinearGradient::LinearGradient | ( | double | x0,
|  | double | y0,
|  | double | x1,
|  | double | y1 |
| ) |  |  | `[protected]`

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

## Member Function Documentation

static RefPtr<LinearGradient> Cairo::LinearGradient::create | ( | double | x0,
|  | double | y0,
|  | double | x1,
|  | double | y1 |
| ) |  |  | `[static]`

void Cairo::LinearGradient::get_linear_points | ( | double & | x0,
|  | double & | y0,
|  | double & | x1,
|  | double & | y1 |
| ) |  |  | const

Parameters:

  | x0 | return value for the x coordinate of the first point
  | y0 | return value for the y coordinate of the first point
  | x1 | return value for the x coordinate of the second point
  | y1 | return value for the y coordinate of the second point

Gets the gradient endpoints for a linear gradient.
