If you're especially lazy and want something else to do all the work, try
using an imagelist
(I'm assuming your four little bitmaps are the sime size and shape)
The in your OnDrawCell event you can use
ImageList.Draw( Canvas, Rect.Left, Rect.Top, ImageIndex )
Be sure to set your imagelist masked property to true.
Image index is of course the thing you use to pick which of the images is
drawn.
