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.
