     Renders a rectangular portion of a pixbuf to a drawable.  The
     destination drawable must have a colormap. All windows have a
     colormap, however, pixmaps only have colormap by default if they
     were created with a non-'NULL' window  argument. Otherwise a
     colormap must be set on them with  'gdkDrawableSetColormap'.

     gdkDrawPixbuf(object, gc = NULL, pixbuf, src.x, src.y, dest.x, dest.y, width = -1, height = -1, dither = "GDK_RGB_DITHER_NORMAL", x.dither = 0, y.dither = 0)

_A_r_g_u_m_e_n_t_s:

'object': ['GdkDrawable']  Destination drawable.

    'gc': ['GdkGC']  a 'GdkGC', used for clipping, or 'NULL'

'pixbuf': ['GdkPixbuf']  a 'GdkPixbuf'

 'src.x': [integer]  Source X coordinate within pixbuf.

 'src.y': [integer]  Source Y coordinates within pixbuf.

'dest.x': [integer]  Destination X coordinate within drawable.

'dest.y': [integer]  Destination Y coordinate within drawable.

 'width': [integer]  Width of region to render, in pixels, or -1 to use
          pixbuf width.

'height': [integer]  Height of region to render, in pixels, or -1 to
          use pixbuf height.

'dither': ['GdkRgbDither']  Dithering mode for 'GdkRGB'.

'x.dither': [integer]  X offset for dither.

'y.dither': [integer]  Y offset for dither.

_D_e_t_a_i_l_s:

     On older X servers, rendering pixbufs with an alpha channel
     involves round  trips to the X server, and may be somewhat slow.

     The clip mask of 'gc' is ignored, but clip rectangles and clip
     regions work fine.

     If GDK is built with the Sun mediaLib library, the gdk_draw_pixbuf
     function is accelerated using mediaLib, which provides hardware
     acceleration on Intel, AMD, and Sparc chipsets.  If desired,
     mediaLib support can be turned off by setting the
     GDK_DISABLE_MEDIALIB environment variable.  

     Since  2.2
