Good day all

Could somebody give a hint ? How do rotate canvas node (triangle or Rectangular, for example )?

Most of node classes are derived from TPolygonalNode class. This objects holds the vertices of the shape. Theoretically you can rotate the vertex points array of a TPolygonalNode object.

You can use RotatePoints global procedure to rotate an array of points around and arbitrary origin.
