ImageTools[Rotate] - rotate an image in increments of 90 degrees
Calling Sequence
Rotate( img, angle, opts )
Parameters
img
-
Image; input image
angle
degrees of rotation, an integral multiple of 90
opts
(optional) equation(s) of the form option = value; specify options for the Rotate command
Description
The Rotate command returns an image that has been rotated by angle degrees. Only rotations in steps of 90 degrees are supported.
The img parameter is of type Image.
The angle parameter specifies the angle of rotation in a clockwise direction. It may be an integral multiple of 90 or one of the names left or right. An angle of 90 degrees is equivalent to right.
The start row and column indices are preserved. If the input image starting row and column indices are m and n, respectively, then the output image starting row and column indices are m and n, respectively.
Options
output = Image
Specifies a data structure into which the output is written. This can be used to avoid allocating memory. The size and number of layers must match that of the input. The dimensions of the output image are adjusted so that the row and column indices match the input. The default is NULL.
