# draw_ellipse

## Draws an ellipse.

### 语法：

draw_ellipse(x1, y1, x2, y2, outline);

参数 |
描述 |

x1 |
The x coordinate of the left of the ellipse. |

y1 |
The y coordinate of the top of the ellipse. |

x2 |
The x coordinate of the right of the ellipse. |

y2 |
The y coordinate of the bottom of the ellipse. |

outline |
Whether the ellipse is drawn filled (false) or as a one pixel
wide outline (true). |

**返回：** N/A（无返回值）

### 描述

With this function you can draw either an outline of an ellipse
or a filled ellipse by defining a rectangular area that will then
have the ellipse created to fit. You can define how precise the
drawing is with the function `draw_set_circle_precision`.

**NOTE**: If you are wanting to draw a shape
using a shader, you should be aware that most shaders expect the
following inputs: vertex, texture, Colour. However, when using this
function, only vertex and colour data are being passed in, and so
the shader may not draw anything (or draw something but not
correctly). If you need to draw shapes in this way then the shader
should be customised with this in mind.

### 例如：

draw_set_colour(c_white);

draw_ellipse(100, 100, 300, 200, false);

This will draw a filled ellipse within the defined rectangular
area.
