Method scale: object scale(float factor)
object scale(0.5)
object scale(float xfactor, float yfactor)
Description: scales the image with a factor, 0.5 is an optimized case.
Parameter factor: factor to use for both x and y
Parameter xfactor
Parameter yfactor: separate factors for x and y
Returns: the new image object

Method scale: object scale(int newxsize, int newysize)
object scale(0, int newysize)
object scale(int newxsize, 0)
Description: scales the image to a specified new size, if one of newxsize or newysize is 0, the image aspect ratio is preserved.
Parameter newxsize
Parameter newysize: new image size in pixels
Returns: the new image object
