 The following code appeared in MacTutor a while back. I think it came
from David Dunham, but I'm not positive. I also recall that there were
some caveats attached, but I don't remember them. Hope it helps anyway.

/*
	PlotSICN.c
	Draw the sicnNumth small icon of sicn in sicnRect of window.

	Note that a dereferenced handle is used (*sicn), but there's no need
	to lock it, since CopyBits() won't alter the heap configuration
	unless a picture or region is being recorded.
*/

PlotSICN (sicn, sicnRect, sicnNum, window)
Handle	sicn;
Rect	*sicnRect;
short	sicnNum;
WindowPtr	window;
{
	BitMap	sicnBits;

	/* set up the bitmap */
	sicnBits.rowBytes = 2;
	SetRect(&sicnBits.bounds, 0, 0, 16, 16);
	sicnBits.baseAddr = *sicn + (sicnNum * 32);
	/* blit the sicn */
	CopyBits(&sicnBits, &window->portBits,
		&sicnBits.bounds, sicnRect, srcCopy, NIL);
}
