HP HP-UX User Manual

 
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.
