From the Xlib document...

	To create a pixmap and then store bitmap-format data into
	it, use XCreatePixmapFromBitmapData.
	
	Pixmap XCreatePixmapFromBitmapData(display, d, data, width, height, fg, bg, depth)
	     Display *display;
	     Drawable d;
	     char *data;
	     unsigned int width, height;
	     unsigned long fg, bg;
	     unsigned int depth;
	
	display   Specifies the connection to the X server.
	
	d         Specifies the drawable that indicates the screen.
	
	data      Specifies the data in bitmap format.
	
	width
	height    Specify the width and height.
	
	fg
	bg        Specify the foreground and background pixel values
	          to use.
	
	depth     Specifies the depth of the pixmap.
	
	The XCreatePixmapFromBitmapData function creates a pixmap of
	the given depth and then does a bitmap-format XPutImage of
	the data into it.  The depth must be supported by the screen
	of the specified drawable, or a BadMatch error results.
	
	XCreatePixmapFromBitmapData can generate BadAlloc and Bad-
	Match errors.
