XMAG(1)

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.
