Description

Get the number of vertex codes within a Py5Shape object. The vertex codes can be used to inspect a shape’s geometry to determine what kind of vertices it has. Each can be one of BREAK, VERTEX, BEZIER_VERTEX, QUADRATIC_VERTEX or CURVE_VERTEX.

The vertex codes will not necessarily align with the vertices because number of vertex codes may be larger than the number of vertices. This will be the case for shapes that use contours, and therefore contain BREAK codes.

Underlying Java method: PShape.getVertexCodeCount

Syntax

get_vertex_code_count() -> int
