goc_group_add_child ()

void
goc_group_add_child (GocGroup *parent,
                     GocItem *item);

Adds item as a new child to parent .

goc_group_adjust_bounds ()

void
goc_group_adjust_bounds (GocGroup const *group,
                         double *x0,
                         double *y0,
                         double *x1,
                         double *y1);

Adds group horizontal offset to x0 and x1 , and vertical offset to y0 and y1 . This function is called recursively so that when returning x0 , y0 , x1 , and y1 are absolute coordinates in canvas space,

goc_group_adjust_coords ()

void
goc_group_adjust_coords (GocGroup const *group,
                         double *x,
                         double *y);

Adds group horizontal offset to x0 , and vertical offset to y0 . This function is called recursively so that when returning x0 and y0 are absolute coordinates in canvas space,

goc_group_cairo_transform ()

void
goc_group_cairo_transform (GocGroup const *group,
                           cairo_t *cr,
                           double x,
                           double y);

Translates cr current context so that operations start at (x ,y ), which are group relative coordinates, and is scaled according to the containing GocCanvas current scale (see goc_canvas_get_pixels_per_unit()). The translation takes all group ancestors into account.

This function does not call cairo_save().

goc_group_clear ()

void
goc_group_clear (GocGroup *group);

Destroys all group children.

goc_group_new ()

GocGroup *
goc_group_new (GocGroup *parent);

Creates a new GocGroup as a child of parent .

goc_group_remove_child ()

void
goc_group_remove_child (GocGroup *parent,
                        GocItem *item);

Removes item from parent . This function will fail if item is not a child of parent .

goc_group_set_clip_path ()

void
goc_group_set_clip_path (GocGroup *group,
                         GOPath *clip_path,
                         cairo_fill_rule_t clip_rule);

Clips the drawing inside path .
