[Gtk-sharp-list] Using images with transparency

I need to superimpose an image with a transparent background on top of
another image. The idea is to have a 2D map within a game that is made
up of tiles upon which images of the player character's tiles can be
superimposed so that the character image doesn't obliterates the map but
is put on top, much like a sprite works (but without the animation).
I've tried using a pixmap to place a pixbuf image in the pixmap and then
a test image with a transparent background in the pixmap afterwards, but
the test image simply overwrites the original. An except from my
program is included at the bottom.
Can anyone please help me with this?
// This draws a map comprised of j * i grass1 tiles from a pixbuf
for (int i = 0; i < map.length; i++)
for (int j = 0; j < map.breadth; j++)
pixMap.DrawPixbuf (d.Style.BlackGC, grass1, 0, 0, j * 50, i * 50,
50, 50, Gdk.RgbDither.None, 0, 0);
// This is meant to superimpose the test player character tile with
transparent background in the upper left hand corner
pixMap.DrawPixbuf (d.Style.BlackGC, test, 0, 0, 0, 0, 50, 50,
Gdk.RgbDither.None, 0, 0);
