Image(or matrix) rotation and scaling function
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)
interpMethod:
'nearest' - nearest neighbor interpolation
'linear' - bilinear interpolation (defalt)
'spline' - spline interpolation
'cubic' - bicubic interpolation
padding: background filling color (0~255, black~white). Default: black
Example:
im = imread('cameraman.tif')
imshow(imTransform(im,pi/6))
