SYNOPSISxmag [-mag magfactor] [-source geom] [-toolkitoption...]
OPTIONS
This option specifies the size and/or location of the source region on
the screen. By default, a 64x64 square is provided for the user to
select an area of the screen. This option indicates the magnification
to be used. 5 is the default.
DESCRIPTION
The xmag program allows you to magnify portions of an X screen. The
magnification occurs on the screen specified by the $DISPLAY environ‐
mental variable or by the -display command line option regardless of
location of the mouse pointer in a multi-screen display. 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.
WIDGETSxmag 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
application. Indentation indicates hierarchical structure. The widget
class name is given first, followed by the widget instance name.
