xmag - magnify parts of the screen
xmag [-mag magfactor] [-source geom] [-toolkitoption...]
This option specifies the size and/or location of the
source region on the screen. By default, a 64x64 square
is provided for the user to select an area of the screen.
This option indicates the magnification to be used. 5 is
the default.
The xmag program allows you to magnify portions of an X
screen. The magnification occurs on the screen specified
by the $DISPLAY environmental variable or by the -display
command line option regardless of location of the mouse
pointer in a multi-screen display. 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 instance
name.
