NAME

       xmag - magnify parts of the screen


SYNOPSIS

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


DESCRIPTION

       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 indicat
       ing  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 posi
       tion  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	 magnifi
       cation  instance.   New brings up the rubber band selector
       to create a new magnification instance.	Cut puts the mag
       nification 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.  Resiz
       ing xmag resizes the magnification area.	  xmag	preserves
       the colormap, visual, and window depth of the source.


WIDGETS

       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.
