Experts:

I'm trying to write some text onto a bitmap:

	uchar	image[HT][WID];
	Pixmap	bm;

	bm = XCreateBitmapFromData(TheDisplay, XtWindow(PageBox),
					image, WID*8, HT);
	XDrawString(TheDisplay, bm, DefaltGC, 10, 10, "SomeText", 8);

But I get the following runtime error:

X Protocol error:  BadMatch, invalid parameter attributes
  Major opcode of failed request:  74 (X_PolyText8)
  Minor opcode of failed request:  0
  Resource id in failed request:  0x40001a
  Serial number of failed request:  55
  Current serial number in output stream:  56

What's going on?  (This is on X11R3).

BTW, I tried using XCreatePixmapFromBitmapData, and that worked
when depth was set to 4, but failed when depth was set to 1.
I wouldn't normally argue with success, but the speed difference
between displaying an XCreateBitmap... vs. XCreatePixmap...(depth=4)
is considerable, and I only need Black and White.
