anim.plane.polygon

class anim.plane.polygon(points, x=0, y=0, position=None, color='grey', stroke=None, thickness=0.005, linestyle='-', group=None, center_of_rotation=[0, 0], orientation=0, zvalue=0, draggable=False, clickable=False)

A polygon item is defined by its:

• reference point

• polygon points (locations relative to the point of reference)

• styling

Parameters ══════════

• name

  str The polygon’s name

• group

  anim.plane.group default: None The polygon’s group. If None, the position of the reference point is in absolute coordinates. Otherwise, the positions are relative to the group’s reference point.

─── positions ───────────────────────────────

• x

  float default: 0 x-position of the reference point.

• y

  float default: 0 y-position of the reference point.

• position

  (float, float), [float, float], complex default: [0,0] Position of the reference point. The user can define either x, y or the position. In case of conflict, the position attribute wins.

• points

  [(float, float)], [[float, float]], [complex] Positions of the polygon points, with respect to the reference point

─── transformations ─────────────────────────

• orientation

  float default: 0, unit: radians Orientation of the polygon, with respect to the positive part of the x-axis.

• center_of_rotation

  (float, float), [float, float], complex default: None Center point for the rotation, relative to the reference point.

• draggable

  bool default: False Boolean specifying if the item can be dragged. If True, the dragging callback is defined in the ‘itemChange’ method of the event class, which is transfered to the canva’s ‘event’ method (recommended).

─── stack ───────────────────────────────────

• zvalue

  float default: 0 Z-value (stack order) of the polygon.

─── style ────────────────────────────────

• color

  None, str, QColor default: ‘grey’ Fill color. None stands for transparency.

• stroke

  None, str, QColor default: None Stroke color. None stands for transparency.

• thickness

  float default: 0.005 Stroke thickness, in scene units. When it is equal to 0, the stroke has the minimal thickness of 1 pixel.

• linestyle

  ‘solid’/’-’, ‘dash’/’–’, ‘dot’/’..’/’:’, ‘dashdot’/’-.’ default: ‘-’ Stroke style.
