Returns a new image that is the result of scaling this image, but without changing the canvas size.
This can be thought of as similar to zooming in on a camera. When you zoom on a camera, the size of the viewpane does not increase, and some parts of the image are no longer visible.
zoom operation accepts a scale factor to apply to the dimensions, and optionally a scale method. If
the scale method is not specified, then BICUBIC is used.
Using this image as our input:
// zoom with default scale method image.zoom(1.3)
// zoom with a specified scale method. image.scaleToHeight(200, Scalemethod.FastScale)
