A ShapePath represents one key of spline data for a shape.
Attributes
Read-only unless otherwise noted.
| Name | Description | Added |
|---|---|---|
| bounds | the bounding box | |
| clockwise | True if clock-wise | |
| closed | True if closed (read/write) | |
| flags | a List of Integers representing the flags for each control point | |
| numPoints | the number of control points | |
| points | a List of tuples containing the control point information. The format of the tuples is dependent on the shape type. Bezier - (in_tangent, control_point, out_tangent) | |
| range | a Tuple (start, end) with the t-value range for this shape type | |
| type | the Shape Type |
Methods
| Name | Description |
|---|---|
| clone() | returns a copy of the path |
| evalDerivative(t) | evaluate the derivative at t |
| evalPoint(t) | evaluate the point at t |
| interpolate(path, t) | generate and return a new ShapePath by interpolating with path using t |
| selected(index) | True if the control point at index is selected |
| transform(Matrix, selected=False) | transform all (or just the selected) points by the Matrix |
Constants
Control Point Flags
| Name | Description |
|---|---|
| Flag_Selected | The control point is selected |
| Flag_Tagged | The control point is tagged |
