XMAG(1) X11 R4.11MU05 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

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