Description

Functions

go_pattern_as_str ()

char const	*
go_pattern_as_str (GOPatternType pattern);

Returns


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. The returned surface must be freed after use, using cairo_pattern_destroy.


go_pattern_from_str ()

GOPatternType
go_pattern_from_str (char const *name);

Returns


go_pattern_get_pattern ()

guint8 const 	*
go_pattern_get_pattern (GOPattern const *pat);

Returns


go_pattern_get_svg_path ()

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

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
