Rotate an image using the 'nearest' or 'bilinear' method
Rotate an image by angle using the 'nearest' or 'bilinear' method
rotateImage(image, angle, method = "nearest", mode = "same", threads = 1)
image |
matrix, data frame or 3-dimensional array |
angle |
specifies the number of degrees |
method |
a string specifying the interpolation method when rotating an image ( 'nearest', 'bilinear' ) |
mode |
one of 'full', 'same' (same indicates that the ouput image will have the same dimensions with initial image) |
threads |
the number of cores to run in parallel |
This function rotates an image by a user-specified angle
depending on the input, either a matrix or an array
path = system.file("tmp_images", "2.jpg", package = "OpenImageR")
image = readImage(path)
r = rotateImage(image, 75, threads = 1)Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
