XMAG(1)             UNIX Programmer's Manual              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 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.

WIDGETS

     xmag uses the X Toolkit and the Athena Widget Set. The mag-
     nified 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.
