NAME
       ImageByteOrder, BitmapBitOrder, BitmapPad, BitmapUnit,
       DisplayHeight, DisplayHeightMM, DisplayWidth, Display
       WidthMM, XListPixmapFormats, XPixmapFormatValues - image
       format functions and macros

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
		 supported by the display.

       screen_number
		 Specifies the appropriate screen number on the
		 host server.

DESCRIPTION
       The XListPixmapFormats function returns an array of
       XPixmapFormatValues 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 dis
       played 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 scan
       line unit in bits.

       The DisplayHeight macro returns the height of the speci
       fied 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 speci
       fied 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;
