This function takes an image or matrix and rotate it by theta (radian, rigid motion)
The image could also be enlarged or shrinked by an optional scaling factor

img: input image (or or a 2D Matrix)
dtheta: the amount of rotation in radian
scale: a scalar number that scales the image (default=1)
'nearest' - nearest neighbor interpolation
'linear' - bilinear interpolation (defalt)
'spline' - spline interpolation
'cubic' - bicubic interpolation
padding: background filling color (0~255, black~white). Default: black

im = imread('cameraman.tif')
