\section{Detailed Description}{The most basic way to create a pixbuf is to wrap an existing pixel
buffer with a \code{\link{GdkPixbuf}} structure.  You can use the
\code{\link{gdkPixbufNewFromData}} function to do this You need to specify
the destroy notification function that will be called when the
data buffer needs to be freed; this will happen when a \code{\link{GdkPixbuf}}
is finalized by the reference counting functions If you have a
chunk of static data compiled into your application, you can pass
in \code{NULL} as the destroy notification function so that the data
will not be freed.
  
The \code{\link{gdkPixbufNew}} function can be used as a convenience to
create a pixbuf with an empty buffer.  This is equivalent to
allocating a data buffer using \code{malloc()} and 
then wrapping it with \code{\link{gdkPixbufNewFromData}}. The \code{\link{gdkPixbufNew}} 
function will compute an optimal rowstride so that rendering can be 
performed with an efficient algorithm.
  
As a special case, you can use the \code{\link{gdkPixbufNewFromXpmData}}
function to create a pixbuf from inline XPM image data.
  
You can also copy an existing pixbuf with the \code{\link{gdkPixbufCopy}}
function.  This is not the same as just doing a \code{gObjectRef()}
on the old pixbuf; the copy function will actually duplicate the
pixel data in memory and create a new \code{\link{GdkPixbuf}} structure for it.}
