XMAG(1) General Commands Manual 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 re-
gion 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 magni-
fication 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 pro-
gram. 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 xmag ap-
plication. Indentation indicates hierarchical structure. The widget
class name is given first, followed by the widget instance name.
