ZOOM  ZOOM Image Zoom Function


Usage
 
 This function changes the zoom factor associated with the currently active
 image.  It is a legacy support function only, and thus is not quite equivalent
 to the zoom function from previous versions of FreeMat.  However, it should
 achieve roughly the same effect. The generic syntax for its use is
 
   zoom(x)
 
 where x is the zoom factor to be used.  The exact behavior of the zoom
 factor is as follows:
   -  x>0 The image is zoomed by a factor x in both directions.
   -  x=0 The image on display is zoomed to fit the size of the image window, but  the aspect ratio of the image is not changed.  (see the Examples section formore details).  This is the default zoom level for images displayed with theimage command.
   -  x<0 The image on display is zoomed to fit the size of the image window, with  the zoom factor in the row and column directions chosen to fill the entire window.  The aspect ratio of the image is not preserved.  The exact value of x is  irrelevant.
