Create a new linear gradient Cairo::Pattern along the line defined by (x0, y0) and (x1, y1).
Before using the gradient pattern, a number of color stops should be defined using Cairo::Gradient::add_color_stop_rgb() or Cairo::Gradient::add_color_stop_rgba().
Note: The coordinates here are in pattern space. For a new pattern, pattern space is identical to user space, but the relationship between the spaces can be changed with Cairo::Pattern::set_matrix().
- Parameters
-
| x0 | x coordinate of the start point |
| y0 | y coordinate of the start point |
| x1 | x coordinate of the end point |
| y1 | y coordinate of the end point |
