XMAG(1)                                                                                              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 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 rub-ber rubber
       ber 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.

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  struc-ture structure
       ture  of the xmag application.  Indentation indicates hierarchical  structure.  The widget class name
       is given first, followed by the widget instance name.
