Methods

CopyTo(Span<PointF>, bool, Vector2)

Writes the segment's linearized points to destination, baked at the supplied device-space scale.

public void CopyTo(Span<PointF> destination, bool skipFirstPoint, Vector2 scale)

Parameters

destination Span<PointF>

The destination point span.

skipFirstPoint bool

Whether to skip the first emitted point.

scale Vector2

The X/Y scale at which curves are flattened. Pass One for local-space output.

GetControlPoints()

Gets the control points of this curve.

public ReadOnlyMemory<PointF> GetControlPoints()

Returns

ReadOnlyMemory<PointF>

The control points of this curve.

LinearVertexCount(Vector2)

Returns the number of linear vertices emitted by this segment when flattened under the supplied device-space scale.

public int LinearVertexCount(Vector2 scale)

Parameters

scale Vector2

The X/Y scale at which curves are flattened. Pass One for local-space counts.

Returns

int

The number of linear vertices this segment emits.

Transform(Matrix4x4)

Transforms this line segment using the specified matrix.

public CubicBezierLineSegment Transform(Matrix4x4 matrix)

Parameters

matrix Matrix4x4

The matrix.

Returns

CubicBezierLineSegment

A line segment with the matrix applied to it.
