    NAME
         ImageByteOrder, BitmapBitOrder, BitmapPad, BitmapUnit,
         DisplayHeight, DisplayHeightMM, DisplayWidth,
         DisplayWidthMM, 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 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;
