XMAG(1) X Version 11(Release 5) 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.
WIDGETS

is displayed in the Scale widget. For more information, see the Athena
