    <summary>In memory image handling and representation.</summary>
    <remarks>
      <para>
	The <see cref="T:Gdk.Pixbuf" /> class is used to represent an image in
	memory.  The in-memory representation uses either a three
	byte RGB representation or a four byte RGBA representation.  
      </para>
      <para>
	Pixbufs can be created from a number of sources: image files
	in an assorted set of file formats (png, tiff, jpg, gif, xpm,
	pcx, ico, xpm, xbm);  Drawables (which can be windows on the X
	server, or off-screen images in the X server) or in-memory
	images.
      </para>
      <para>
	A pixbuf can be rendered, scaled or composited into another
	pixbuf, into a window on the X server, or on a drawable in the
	X server.  Various rendering methods are provided for this
	purpose.
      </para>
      <para>
	Pixbufs can also be saved to a number of different file
	formats.

        <remarks>
          <para>
	    Transfers image data from a <see cref="T:Gdk.Image" /> and
	    converts it to an RGB(A) representation inside a <see cref="T:Gdk.Pixbuf" />. In other words, copies image data
	    from the Image (which might be potentially shared using
	    shared memory between the client and the server) to a
	    client-side RGB(A) buffer (the Pixbuf). This allows you to
	    efficiently read individual pixels on the client side.
	  </para>
          <para>
	    If the <paramref name="image" /> has no colormap (<see cref="P:Gdk.Image.Colormap" /> returns <see langword="null" />), then a suitable colormap must be
	    specified. Typically a <see cref="T:Gdk.Window" /> or a
	    pixmap created by passing a <see cref="T:Gdk.Window" /> to
	    the <see cref="T:Gdk.Pixmap" /> constructor will already
	    have a colormap associated with it.  If the <paramref name="image" /> has a colormap, the <paramref name="cmap" /> argument will be ignored. If the <paramref name="image" /> is a bitmap (1 bit per pixel pixmap),
	    then a colormap is not required; pixels with a value of 1
	    are assumed to be white, and pixels with a value of 0 are
	    assumed to be black.  For taking screenshots, the <see cref="P:Gdk.Colormap.System" /> property returns the
	    correct colormap to use.
	  </para>
          <para>
	    If the specified destination pixbuf <paramref name="dest" /> is <see langword="null" />, then this
	    function will create an RGB Pixbuf with 8 bits per channel
	    and no alpha, with the same size specified by the width
	    and height arguments. In this case, the <paramref name="dest_x" /> and <paramref name="dest_y" /> arguments
	    must be specified as 0. If the specified destination
	    pixbuf is not <see langword="null" /> and it contains alpha
	    information, then the filled pixels will be set to full
	    opacity (alpha = 255).
	  </para>
          <para>
	    If the specified <paramref name="image" /> is a pixmap,
	    then the requested source rectangle must be completely
	    contained within the pixmap, otherwise the function will
	    return <see langword="null" />. For pixmaps only (not for
	    windows) passing -1 for <paramref name="width" /> or
	    <paramref name="height" /> is allowed, to mean the full
	    width or height of the pixmap.
	  </para>
          <para>
	    If the specified <paramref name="image" /> is a window,
	    and the window is off the screen, then there is no image
	    data in the obscured/offscreen regions to be placed in the
	    pixbuf.  The contents of portions of the <see cref="T:Gdk.Pixbuf" /> corresponding to the offscreen
	    region are undefined.
	  </para>
          <para>
	    If the window you are obtaining data from is partially
	    obscured by other windows, then the contents of the Pixbuf
	    areas corresponding to the obscured regions are undefined.
	  </para>
          <para>
	    If the target image is not mapped (typically because
	    it's iconified/minimized or not on the current workspace),
	    then <see langword="null" /> will be returned.
	  </para>
          <para>
	    If memory can't be allocated for the return value, <see langword="null" /> will be returned instead.
	  </para>
          <para>
	    (In short, there are several ways this function can fail,
	    and if it fails it returns <see langword="null" />; so
	    check the return value.)

	    Renders a rectangular portion of the Pixbuf into the

	    visual and colormap.  Note that this function will ignore
	    the opacity information for images with an alpha channel;
	    the GC must already have the clipping mask set if you want
	    transparent regions to show through.
	  </para>
          <para>
	    For an explanation of dither offsets, see the GdkRGB
	    documentation.  In brief, the dither offset is important
	    when re-rendering partial regions of an image to a
	    rendered version of the full image, or for when the
	    offsets to a base position change, as in scrolling. The
	    dither matrix has to be shifted for consistent visual
	    results. If you do not have any of these cases, the dither
	    offsets can be both zero.

	    The value of the Pixbuf (the same one that was passed) or

        <remarks>
          <para>
	    Transfers image data from a <see cref="T:Gdk.Drawable" />
	    and converts it to an RGB(A) representation inside a <see cref="T:Gdk.Pixbuf" />. In other words, copies image data
	    from a server-side drawable to a client-side RGB(A)
	    buffer. This allows you to efficiently read individual
	    pixels on the client side.
	  </para>
          <para>
	    If the <paramref name="drawable" /> has no colormap (<see cref="P:Gdk.Drawable.Colormap" /> returns <see langword="null" />), then a suitable colormap must be
	    specified. Typically a <see cref="T:Gdk.Window" /> or a
	    pixmap created by passing a <see cref="T:Gdk.Window" /> to
	    the <see cref="T:Gdk.Pixmap" /> constructor will already
	    have a colormap associated with it.  If the <paramref name="drawable" /> has a colormap, the <paramref name="cmap" /> argument will be ignored. If the <paramref name="drawable" /> is a bitmap (1 bit per pixel pixmap),
	    then a colormap is not required; pixels with a value of 1
	    are assumed to be white, and pixels with a value of 0 are
	    assumed to be black.  For taking screenshots, the <see cref="P:Gdk.Colormap.System" /> property returns the
	    correct colormap to use.
	  </para>
          <para>
	    If the specified destination pixbuf <paramref name="dest" /> is <see langword="null" />, then this
	    function will create an RGB Pixbuf with 8 bits per channel
	    and no alpha, with the same size specified by the width
	    and height arguments. In this case, the <paramref name="dest_x" /> and <paramref name="dest_y" /> arguments
	    must be specified as 0. If the specified destination
	    pixbuf is not <see langword="null" /> and it contains alpha
	    information, then the filled pixels will be set to full
	    opacity (alpha = 255).
	  </para>
          <para>
	    If the specified <paramref name="drawable" /> is a pixmap,
	    then the requested source rectangle must be completely
	    contained within the pixmap, otherwise the function will
	    return <see langword="null" />. For pixmaps only (not for
	    windows) passing -1 for <paramref name="width" /> or
	    <paramref name="height" /> is allowed, to mean the full
	    width or height of the pixmap.
	  </para>
          <para>
	    If the specified <paramref name="drawable" /> is a window,
	    and the window is off the screen, then there is no image
	    data in the obscured/offscreen regions to be placed in the
	    pixbuf.  The contents of portions of the <see cref="T:Gdk.Pixbuf" /> corresponding to the offscreen
	    region are undefined.
	  </para>
          <para>
	    If the window you are obtaining data from is partially
	    obscured by other windows, then the contents of the Pixbuf
	    areas corresponding to the obscured regions are undefined.
	  </para>
          <para>
	    If the target drawable is not mapped (typically because
	    it's iconified/minimized or not on the current workspace),
	    then <see langword="null" /> will be returned.
	  </para>
          <para>
	    If memory can't be allocated for the return value, <see langword="null" /> will be returned instead.
	  </para>
          <para>
	    (In short, there are several ways this function can fail,
	    and if it fails it returns <see langword="null" />; so
	    check the return value.)
	  </para>
          <para>
	    This function calls <see cref="M:Gdk.Drawable.GetImage(int,int,int,int)" />
	    internally and converts the resulting image to a <see cref="T:Gdk.Pixbuf" />, so the documentation for <see cref="M:Gdk.Drawable.GetImage(int,int,int,int)" /> is also
	    relevant.
