xmag - magnify parts of the screen


   xmag [ -mag magfactor ] [ -source geom ] [ -toolkitoption ... ]


   The  xmag program allows you to magnify portions of an X screen.  If no
   explicit region is specified, a square with the pointer  in  the  upper
   left  corner is displayed indicating the area to be enlarged.  The area
   can be dragged out to the desired size by pressing Button  2.   Once  a
   region  has  been  selected,  a  window is popped up showing a blown up
   version of the region in which  each  pixel  in  the  source  image  is
   represented  by  a small square of the same color.  Pressing Button1 in
   the enlargement window shows the position and RGB value  of  the  pixel
   under the pointer until the button is released.  Typing ``Q'' or ``^C''
   in the enlargement window exits the program.   The  application  has  5
   buttons  across  its  top.  Close deletes this particular magnification
   instance.  Replace brings up the rubber band selector again  to  select
   another  region  for  this  magnification  instance.  New brings up the
   rubber band selector to create a new  magnification  instance.   Select
   puts  the magnification image into the primary selection.  Paste copies
   the primary selection buffer into xmag.  Note  that  you  can  cut  and
   paste  between  xmag and the bitmap program.  Resizing xmag resizes the
   magnification area.  xmag preserves the colormap,  visual,  and  window
   depth of the source.


   xmag uses the X Toolkit and the Athena Widget Set.  The magnified image
   is displayed in the Scale widget.  For more information, see the Athena
   Widget  Set  documentation.   Below is the widget structure of the xmag
   application.   Indentation  indicates  hierarchical   structure.    The
   widget class name is given first, followed by the widget instance name.

   -source geom   This  option  specifies  the size and/or location of the
                  source region on the screen.  By default, a 64x64 square
                  is  provided  for  the  user  to  select  an area of the

   -mag integer   This option indicates the magnification to be  used.   5
                  is the default.
