## Functions

### go_marker_assign ()

    void
    go_marker_assign (GOMarker *dst,
                      GOMarker const *src);

### go_marker_create_cairo_surface ()

    cairo_surface_t *
    go_marker_create_cairo_surface (GOMarker const *marker,
                                    cairo_t *cr,
                                    double scale,
                                    double *width,
                                    double *height);

Creates a new cairo surface similar to the current target of `cr` , and render `marker` on it. `center` will contain the coordinate of the center of the surface.

#### Parameters

marker | a GOMarker |
cr | a cairo context |
scale | current context scale |
width | a placeholder for the surface width |
height | a placeholder for the surface height |

#### Returns

a newly created cairo_surface_t. This surface should be destroyed using cairo_surface_destroy after use.

### go_marker_dup ()

    GOMarker *
    go_marker_dup (GOMarker const *src);

Duplicates `src` .

#### Parameters

src | the GOMarker to duplicate |

#### Returns

the duplicated marker.
