## Description

## Functions

### go_pattern_as_str ()

    char const	*
    go_pattern_as_str (GOPatternType pattern);

### go_pattern_create_cairo_pattern ()

    cairo_pattern_t *
    go_pattern_create_cairo_pattern (GOPattern const *pattern,
                                     cairo_t *cr);

#### Parameters

pattern | a GOPattern |
cr | a cairo context |

#### Returns

a cairo pattern object corresponding to `pattern` parameters.

### go_pattern_from_str ()

    GOPatternType
    go_pattern_from_str (char const *name);

### go_pattern_get_pattern ()

    guint8 const 	*
    go_pattern_get_pattern (GOPattern const *pat);

`go_pattern_get_pattern` is deprecated and should not be used in newly-written code.

### go_pattern_get_svg_path ()

    xmlChar *
    go_pattern_get_svg_path (GOPattern const *pattern,
                             double *width,
                             double *height);

`go_pattern_get_svg_path` is deprecated and should not be used in newly-written code.

Retrieves an SVG path as string, which represents pattern shape. Caller is responsible for freeing the resulting string.

If width != NULL, returns pattern width. If height != NULL, returns pattern height.

#### Parameters

pattern | a GOPattern |
width | pattern width |
height | pattern height |

#### Returns

a xmlChar buffer (free using xmlFree).

### go_pattern_is_solid ()

    gboolean
    go_pattern_is_solid (GOPattern const *pat,
                         GOColor *color);

#### Parameters

pat | GOPattern |
color | GOColor |

#### Returns

if `pat` is solid, and stores the color in `color` . If `pat` is not solid `color` is not touched.

### go_pattern_set_solid ()

    void
    go_pattern_set_solid (GOPattern *pat,
                          GOColor fore);

Makes `pat` a solid pattern with colour `fore` .

#### Parameters

pat | a GOPattern |
fore | a GOColor |

## Types and Values
