@spec boundingRect(t()) ::
  {number(), number(), number(), number()} | {:error, String.t()}

boundingRect

Positional Arguments

• self: Evision.RotatedRect.t()

Return

• retval: Rect

Python prototype (for reference only):

boundingRect() -> retval

@spec points(t()) :: [{number(), number()}] | {:error, String.t()}

points

Positional Arguments

• self: Evision.RotatedRect.t()

Return

• pts: [Point2f].

  The points array for storing rectangle vertices. The order is bottomLeft, topLeft, topRight, bottomRight.

returns 4 vertices of the rotated rectangle Note: Bottom, Top, Left and Right sides refer to the original rectangle (angle is 0), so after 180 degree rotation bottomLeft point will be located at the top right corner of the rectangle.

Python prototype (for reference only):

points() -> pts

@spec rotatedRect() :: t() | {:error, String.t()}

RotatedRect

Return

• self: {centre={x, y}, size={s1, s2}, angle}

Python prototype (for reference only):

RotatedRect() -> <RotatedRect object>

@spec rotatedRect({number(), number()}, {number(), number()}, {number(), number()}) ::
  t() | {:error, String.t()}

@spec rotatedRect({number(), number()}, {number(), number()}, number()) ::
  t() | {:error, String.t()}

Variant 1:

RotatedRect

Positional Arguments

• point1: Point2f
• point2: Point2f
• point3: Point2f

Return

• self: {centre={x, y}, size={s1, s2}, angle}

Any 3 end points of the RotatedRect. They must be given in order (either clockwise or anticlockwise).

Python prototype (for reference only):

RotatedRect(point1, point2, point3) -> <RotatedRect object>

Variant 2:

RotatedRect

Positional Arguments

• center: Point2f.

  The rectangle mass center.

• size: Size2f.

  Width and height of the rectangle.

• angle: float.

  The rotation angle in a clockwise direction. When the angle is 0, 90, 180, 270 etc., the rectangle becomes an up-right rectangle.

Return

• self: {centre={x, y}, size={s1, s2}, angle}
