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 | Added |
---|---|---|
clone() | returns a copy of the path | |
evalDerivative(t) | evaluate the derivative 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 | |
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 |
