XMAG(1) X Version 11 XMAG(1)
Release 6.3
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
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
