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 repre-
sented 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 but-
tons 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. 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 program. Resizing xmag resizes the magnification area. xmag preserves the colormap, visual, and window
depth of the source.
WIDGETS
