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 |
ShapePath Methods
| Name | Description | Added |
|---|---|---|
| insertPoint(t) | inserts a new control point at t | 6.0 |
| deletePoint(index) | deletes the point at index | 6.0 |
| evalNormal(t) | returns the normal at t | 6.0 |
| evalPoint(t) | returns the point information at t | 6.0 |
| Shape Type | No Feather | Per-point Feather |
|---|---|---|
| Closed Bezier | (in_tangent, point, out_tangent) | (in_tangent, point, out_tangent, feather_point, feather_in_tangent, feather_out_tangent) |
| Open Bezier | (in_tangent, point, out_tangent) | (in_tangent, point, out_tangent, stroke_width, feather_width) |
| Closed Bspline | (point, repeat, weight) | (point, repeat, weight, feather_point, feather_weight) |
| Open Bspline | (point, repeat, weight) | (point, repeat, weight, width, feather_width) |
| Closed Xspline | (point, weight) | (point, weight, feather_point, feather_weight) |
| Open Xspline | (point, weight) | (point, weight, width, feather_width) |
