PathForeachFunc
Description:
[ CCode ( instance_pos = 3.9 ) ]
public delegate bool PathForeachFunc (PathOperation op, Point[] pts, float weight)
public delegate bool PathForeachFunc (PathOperation op, Point[] pts, float weight)
Type 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 pts.length 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 |
The operation |
| pts |
The points of the operation |
| weight |
The weight for conic curves, or unused if not a conic curve |
| n_pts |
The number of points |
| user_data |
The user data provided with the function |
Returns:
|
true to continue iterating the path, false to immediately abort and not call the function again. |
