Geometry specifications One of the advantages of using window systems instead of hardwired terminals is that applications don't have to be restricted to a particular size or location on the screen. Although the layout of windows on a display is controlled by the window manager that the user is running (described below), most X programs accept a command line argument of the form: -geometry widthxheight+xoff+yoff (where width, height, xoff, and yoff are numbers) for specifying a preferred size and location for this application's main window. The width and height parts of the geometry specification are usually measured in either pixels or characters, depending on the application. The xoff and yoff parts are measured in pixels and are used to specify the distance of the window from the left (or right) and top (or bottom) edges of the screen, respectively. Both types of offsets are measured from the indicated edge of the screen to the corresponding edge of the window. The X offset may be specified in the following ways: +xoff The left edge of the window is to be placed xoff pixels in from the left edge of the screen (i.e., the X coordinate of the window's origin will be xoff). Xoff may be negative, in which case the window's left edge will be off the screen. -xoff The right edge of the window is to be placed xoff pixels in from the right edge of the screen. xoff may be negative, in which case the window's right edge will be off the screen. The Y offset has similar meanings: +yoff The top edge of the window is to be yoff pixels below the top edge of the screen (i.e. the Y coordinate of the window's origin will be yoff). Yoff may be negative, in which case the window's top edge will be off the screen. -yoff The bottom edge of the window is to be yoff pixels above the bottom edge of the screen. yoff may be negative, in which case the window's bottom edge will be off the screen. Offsets must be given as pairs; in other words, in order to specify either xoff or yoff both must be present. Windows can be placed in the four corners of the screen using the following specifications: • +0+0 (the upper left-hand corner) Graphics Administration Guide For Red Hat Linux 6.2

Geometry specifications
One of the advantages of using window systems instead of hardwired terminals is that
applications don't have to be restricted to a particular size or location on the screen.
Although the layout of windows on a display is controlled by the window manager that
the user is running (described below), most X programs accept a command line argument
of the form:
-geometry
width
x
height
+
xoff
+
yoff
(where
width
,
height
,
xoff
, and
yoff
are numbers) for specifying a preferred size and
location for this application's main window.
The
width
and
height
parts of the geometry specification are usually measured in either
pixels or characters, depending on the application. The
xoff
and
yoff
parts are measured in
pixels and are used to specify the distance of the window from the left (or right) and top
(or bottom) edges of the screen, respectively. Both types of offsets are measured from the
indicated edge of the screen to the corresponding edge of the window. The X offset may
be specified in the following ways:
+xoff
The left edge of the window is to be placed xoff pixels in from the left edge of the
screen (i.e., the X coordinate of the window's origin will be xoff). Xoff may be
negative, in which case the window's left edge will be off the screen.
-xoff
The right edge of the window is to be placed
xoff
pixels in from the right edge of the
screen.
xoff
may be negative, in which case the window's right edge
will be off the screen.
The Y offset has similar meanings:
+
yoff
The top edge of the window is to be
yoff
pixels below the top edge of the screen
(i.e. the Y coordinate of the window's origin will be
yoff
).
Yoff
may be negative, in
which case the window's top edge will be off the screen.
-
yoff
The bottom edge of the window is to be
yoff
pixels above the bottom edge of the
screen.
yoff
may be negative, in which case the window's bottom edge will be off
the screen.
Offsets must be given as pairs; in other words, in order to specify either
xoff
or
yoff
both
must be present. Windows can be placed in the four corners of the screen using the
following specifications:
