     SYNTAX
	  XPixmapFormatValues *XListPixmapFormats(display,
	  count_return)
		Display	*display;
		int *count_return;

	  ImageByteOrder(display)

	  BitmapBitOrder(display)

	  BitmapPad(display)

	  BitmapUnit(display)

	  DisplayHeight(display, screen_number)

	  DisplayHeightMM(display, screen_number)

	  DisplayWidth(display,	screen_number)

	  DisplayWidthMM(display, screen_number)

     ARGUMENTS
	  display   Specifies the connection to	the X server.

	  count_return
		    Returns the	number of pixmap formats that are sup-
		    ported by the display.

	  screen_number
		    Specifies the appropriate screen number on the
		    host server.

     DESCRIPTION
	  The XListPixmapFormats function returns an array of XPixmap-
	  FormatValues structures that describe	the types of Z format
	  images supported by the specified display.  If insufficient
	  memory is available, XListPixmapFormats returns NULL.	 To
	  free the allocated storage for the XPixmapFormatValues
	  structures, use XFree.

	  The ImageByteOrder macro specifies the required byte order
	  for images for each scanline unit in XY format (bitmap) or
	  for each pixel value in Z format.

	  The BitmapBitOrder macro returns LSBFirst or MSBFirst	to
	  indicate whether the leftmost	bit in the bitmap as displayed
	  on the screen	is the least or	most significant bit in	the
	  unit.

	  The BitmapPad	macro returns the number of bits that each
	  scanline must	be padded.

	  The BitmapUnit macro returns the size	of a bitmap's scanline
	  unit in bits.

	  The DisplayHeight macro returns the height of	the specified
	  screen in pixels.

	  The DisplayHeightMM macro returns the	height of the speci-
	  fied screen in millimeters.

	  The DisplayWidth macro returns the width of the screen in
	  pixels.

	  The DisplayWidthMM macro returns the width of	the specified
	  screen in millimeters.

     STRUCTURES
	  The XPixmapFormatValues structure provides an	interface to
	  the pixmap format information	that is	returned at the	time
	  of a connection setup.  It contains:
	  typedef struct {
	       int depth;
	       int bits_per_pixel;
	       int scanline_pad;
	  } XPixmapFormatValues;
