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 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. 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 magni-
fication 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 wid-
get class name is given first, followed by the widget instance name.
