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 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.
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.
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 instance name.
