[code]points[/code] - [PackedVector3Array], containing outline points. [code]x[/code] and [code]y[/code] are point coordinates. [code]z[/code] is the type of the point, using the [enum ContourPointTag] values.
[code]contours[/code] - [PackedInt32Array], containing indices the end points of each contour.
[code]orientation[/code] - [bool], contour orientation. If [code]true[/code], clockwise contours must be filled.
- Two successive [constant CONTOUR_CURVE_TAG_ON] points indicate a line segment.
- One [constant CONTOUR_CURVE_TAG_OFF_CONIC] point between two [constant CONTOUR_CURVE_TAG_ON] points indicates a single conic (quadratic) Bézier arc.
- Two [constant CONTOUR_CURVE_TAG_OFF_CUBIC] points between two [constant CONTOUR_CURVE_TAG_ON] points indicate a single cubic Bézier arc.
- Two successive [constant CONTOUR_CURVE_TAG_OFF_CONIC] points indicate two successive conic (quadratic) Bézier arcs with a virtual [constant CONTOUR_CURVE_TAG_ON] point at their middle.
- Each contour is closed. The last point of a contour uses the first point of a contour as its next point, and vice versa. The first point can be [constant CONTOUR_CURVE_TAG_OFF_CONIC] point.
