I went through a similar process and ended up displaying a DIBitmap by
delaying the creation of the image until the paint method handed me a Graphics
object g. I then created an image with
if (myImage == null) myImage = g.drawSurface.createImage(myDIBitmap);
and displayed it with
g.drawImage(myImage, x, y);
then storing it away for the next time paint was called.
No idea if it's a recommended procedure, but it's presently working.
