xmag - magnify parts of the screen
[ -mag magfactor ] [ -source geom ] [ -toolkitoption ... ]
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
