## Implemented Interfaces

GooCanvasEllipse implements GooCanvasItem.

## Description

GooCanvasEllipse represents an ellipse item.

It is a subclass of GooCanvasItemSimple and so inherits all of the style properties such as "stroke-color", "fill-color" and "line-width".

It also implements the GooCanvasItem interface, so you can use the GooCanvasItem functions such as `goo_canvas_item_raise()` and `goo_canvas_item_rotate()`.

To create a GooCanvasEllipse use `goo_canvas_ellipse_new()`.

To get or set the properties of an existing GooCanvasEllipse, use `g_object_get()` and `g_object_set()`.

The ellipse can be specified either with the "center-x", "center-y", "radius-x" and "radius-y" properties, or with the "x", "y", "width" and "height" properties.

## Functions

### goo_canvas_ellipse_new ()

    GooCanvasItem *
    goo_canvas_ellipse_new (GooCanvasItem *parent,
                            gdouble center_x,
                            gdouble center_y,
                            gdouble radius_x,
                            gdouble radius_y,
                            ...);

Creates a new ellipse item.

Here's an example showing how to create an ellipse centered at (100.0, 100.0), with a horizontal radius of 50.0 and a vertical radius of 30.0. It is drawn with a red outline with a width of 5.0 and filled with blue:

    1
    2
    3
    4
    5
    GooCanvasItem *ellipse = goo_canvas_ellipse_new (mygroup, 100.0, 100.0, 50.0, 30.0,
                                                     "stroke-color", "red",
                                                     "line-width", 5.0,
                                                     "fill-color", "blue",
                                                     NULL);

#### Parameters

parent | the parent item, or `NULL`. If a parent is specified, it will assume ownership of the item, and the item will automatically be freed when it is removed from the parent. Otherwise call `g_object_unref()` to free it. | [skip]
center_x | the x coordinate of the center of the ellipse. |
center_y | the y coordinate of the center of the ellipse. |
radius_x | the horizontal radius of the ellipse. |
radius_y | the vertical radius of the ellipse. |
... | optional pairs of property names and values, and a terminating `NULL`. |

#### Returns

a new ellipse item.
