Usage
# S3 method for im
rotate(X, angle=pi/2, …, centre=NULL)
Arguments
X

A pixel image (object of class "im").

angle

Angle of rotation, in radians.

Ignored.

centre

Centre of rotation. Either a vector of length 2, or a character string (partially matched to "centroid", "midpoint" or "bottomleft"). The default is the coordinate origin c(0,0).

Details

The image is rotated by the angle specified. Angles are measured in radians, anticlockwise. The default is to rotate the image 90 degrees anticlockwise.

Value

Another object of class "im" representing the rotated pixel image.
