Perspective transformation of an image

transform_perspective(
  img,
  startpoints,
  endpoints,
  interpolation = 2,
  fill = NULL
)

Arguments

img

A magick-image, array or torch_tensor.

startpoints

(list of list of ints): List containing four lists of two integers corresponding to four corners [top-left, top-right, bottom-right, bottom-left] of the original image.

endpoints

(list of list of ints): List containing four lists of two integers corresponding to four corners [top-left, top-right, bottom-right, bottom-left] of the transformed image.

interpolation

(int, optional) Desired interpolation. An integer 0 = nearest, 2 = bilinear, and 3 = bicubic or a name from magick::filter_types().

fill

(int or str or tuple): Pixel fill value for constant fill. Default is 0. If a tuple of length 3, it is used to fill R, G, B channels respectively. This value is only used when the padding_mode is constant. Only int value is supported for Tensors.
