XMAG(1)                 FreeBSD General Commands Manual                XMAG(1)

       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.  Cut 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
