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 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 ver-
       sion of the region in which each pixel in the source  image  is  repre-
       sented  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  but-
       tons  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 rub-
       ber band selector to create a new magnification instance.  Cut puts the
       magnification  image into the primary selection.  Paste copies the pri-
       mary selection buffer into xmag.  Note  that  you  can  cut  and  paste
       between  xmag and the bitmap program.  Resizing xmag resizes the magni-
       fication 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.   Below is the widget structure of the xmag
       application.  Indentation indicates hierarchical  structure.  The  wid-
       get class name is given first, followed by the widget instance name.

OPTIONS

       -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
                      screen.

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