25<P>Geometry provides a convenient means to specify a geometry
26argument. The object may be initialized from a C string or C++ string
27containing a geometry specification. It may also be initialized by
28more efficient parameterized constructors.

32<P>X11 geometry specifications are in the form
33<TT>&quot;&lt;width&gt;x&lt;height&gt;{+-}&lt;xoffset&gt;{+-}&lt;yoffset&gt;&quot;</TT>
34(where <I>width</I>, <I>height</I>, <I>xoffset</I>, and <I>yoffset</I>
35are numbers) for specifying the size and placement location for an
36object.
37</P>
38<P STYLE="margin-bottom: 0in">The <I>width</I> and <I>height</I>
39parts of the geometry specification are measured in pixels. The
40<I>xoffset</I> and <I>yoffset</I> parts are also measured in pixels
41and are used to specify the distance of the placement coordinate from
42the left and top and edges of the image, respectively. Both types of
43offsets are measured from the indicated edge of the object to the
44corresponding edge of the image. The X offset may be specified in the
45following ways:

164To Geometry Specifications</H3>
165<P>Any geometry string specification supplied to the Geometry
166constructor is considered to be a Postscript page size nickname if
167the first character is not numeric. The Geometry constructor converts
168these page size specifications into the equivalent numeric geometry
169string specification (preserving any offset component) prior to
170conversion to the internal object format. Postscript page size
171specifications are short-hand for the pixel geometry required to fill
172a page of that size. Since the 11x17 inch page size used in the US
173starts with a digit, it is not supported as a Postscript page size
174nickname. Instead, substitute the geometry specification &quot;<TT>792x1224&gt;&quot;</TT>
175when 11x17 output is desired.
