XMAG(1) X Version 11 (Release 6.6) 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.

magnified image is displayed in the Scale widget. For more
