rotate

torchvision.transforms.functional.rotate(img: Tensor, angle: float, interpolation: InterpolationMode = InterpolationMode.NEAREST, expand: bool = False, center: Optional[List[int]] = None, fill: Optional[List[float]] = None) → Tensor

Rotate the image by angle. If the image is torch Tensor, it is expected to have […, H, W] shape, where … means an arbitrary number of leading dimensions.

Parameters:

• img (PIL Image or Tensor) – image to be rotated.

• angle (number) – rotation angle value in degrees, counter-clockwise.

• interpolation (InterpolationMode) – Desired interpolation enum defined by torchvision.transforms.InterpolationMode. Default is InterpolationMode.NEAREST. If input is Tensor, only InterpolationMode.NEAREST, InterpolationMode.BILINEAR are supported. For backward compatibility integer values (e.g. PIL.Image[.Resampling].NEAREST) are still accepted, but deprecated since 0.13 and will be removed in 0.15. Please use InterpolationMode enum.

• expand (bool, optional) – Optional expansion flag. If true, expands the output image to make it large enough to hold the entire rotated image. If false or omitted, make the output image the same size as the input image. Note that the expand flag assumes rotation around the center and no translation.

• center (sequence, optional) – Optional center of rotation. Origin is the upper left corner. Default is the center of the image.

• fill (sequence or number, optional) –

  Pixel fill value for the area outside the transformed image. If given a number, the value is used for all bands respectively.

  Note

  In torchscript mode single int/float value is not supported, please use a sequence of length 1: [value, ].

Returns:

Rotated image.

Return type:

PIL Image or Tensor
