参数:

• magnitude (int | float | None) – The magnitude used for shear. If None, generate from magnitude_range, see BaseAugTransform. Defaults to None.

• pad_val (int, Sequence[int]) – Pixel pad_val value for constant fill. If a sequence of length 3, it is used to pad_val R, G, B channels respectively. Defaults to 128.

• prob (float) – The probability for performing shear therefore should be in range [0, 1]. Defaults to 0.5.

• direction (str) – The shearing direction. Options are ‘horizontal’ and ‘vertical’. Defaults to ‘horizontal’.

• random_negative_prob (float) – The probability that turns the magnitude negative, which should be in range [0,1]. Defaults to 0.5.

• interpolation (str) – Interpolation method. Options are ‘nearest’, ‘bilinear’, ‘bicubic’, ‘area’, ‘lanczos’. Defaults to ‘bicubic’.

• **kwargs – Other keyword arguments of BaseAugTransform.
