Methods

def c_mirrored(self: ~_Self, *, center: Tuple[float, float] = (0, 0)) -> ~_Self

Inherited from: TransformMixin.c_mirrored

Center mirrored.

def h_mirrored(self: ~_Self, *, x: float = 0) -> ~_Self

Inherited from: TransformMixin.h_mirrored

Horizontal mirrored.

def offsetted(self, offset: float) -> IShape

Args offset

float, offset towards left if positive, towards right if negative

Returns: A new shape. If points of the shape is clockwise, positive offset makes result shape bigger, negative offset makes result shape smaller. If points of the shape is counter-clockwise, positive offset makes result shape smaller, negative offset makes result shape bigger.

def rotated(self: ~_Self, *, degrees: Optional[float] = None, radians: Optional[float] = None,
            origin: Optional[Tuple[float, float]] = None, inplace: Optional[bool] = None) -> ~_Self

Inherited from: TransformMixin.rotated

Return a new cell reference rotated, either degrees or radians must be provided. If both provided, radians is used …

def scaled(self: ~_Self, sx: float, sy: Optional[float] = None, *,
            center: Tuple[float, float] = (0, 0)) -> ~_Self

Inherited from: TransformMixin.scaled

scaled at center.

def transform_combined(self, transform: Affine2D)

Inherited from: TransformMixin.transform_combined

Returns an Affine2D that is the result of the matrix product with the given transformation. It means that the original image can be transformed by a …

def translated(self: ~_Self, tx: float, ty: float) -> ~_Self

Inherited from: TransformMixin.translated

Translated.

def v_mirrored(self: ~_Self, *, y: float = 0) -> ~_Self

Inherited from: TransformMixin.v_mirrored

Vertical mirrored.
