Method
GeglPathclosest_point
Declaration [src]
gdouble
gegl_path_closest_point (
  GeglPath* path,
  gdouble x,
  gdouble y,
  gdouble* on_path_x,
  gdouble* on_path_y,
  gint* node_pos_before
)
Description [src]
Figure out what and where on a path is closest to arbitrary coordinates.
Returns the length along the path where the closest point was encountered.
Parameters
- x
- 
            Type: gdoubleX coordinate. 
- y
- 
            Type: gdoubleY coordinate. 
- on_path_x
- 
            Type: gdouble*Return location for x coordinate on the path that was closest. The argument will be set by the function. 
- on_path_y
- 
            Type: gdouble*Return location for y coordinate on the path that was closest. The argument will be set by the function. 
- node_pos_before
- 
            Type: gint*The node position interpreted before this position was deemed the closest coordinate. The argument will be set by the function.
