Function
GskPathForeachFunc
Declaration
gboolean
(* GskPathForeachFunc) (
GskPathOperation op,
const graphene_point_t* pts,
gsize n_pts,
float weight,
gpointer user_data
)
Description [src]
Prototype of the callback to iterate through the operations of a path.
For each operation, the callback is given the op itself, the points
that the operation is applied to in pts, and a weight for conic
curves. The n_pts argument is somewhat redundant, since the number
of points can be inferred from the operation.
Each contour of the path starts with a GSK_PATH_MOVE operation.
Closed contours end with a GSK_PATH_CLOSE operation.
Parameters
op-
Type:
GskPathOperationThe operation.
pts-
Type:
graphene_point_tThe points of the operation.
The data is owned by the caller of the function. n_pts-
Type:
gsizeThe number of points.
weight-
Type:
floatThe weight for conic curves, or unused if not a conic curve.
user_data-
Type:
gpointerThe user data provided with the function.
The argument can be NULL.The data is owned by the caller of the function.
