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

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





       DisplayHeight(display, screen_number)

       DisplayHeightMM(display, screen_number)

       DisplayWidth(display, screen_number)

       DisplayWidthMM(display, screen_number)

       Specifies the connection to the X server.  Returns the number of pixmap
       formats that are supported by the display.  Specifies  the  appropriate
       screen number on the host server.

       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, XListPixmapFor‐
       mats returns NULL. To free the allocated storage for the XPixmapFormat‐
       Values 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

       The  DisplayHeight  macro returns the height of the specified screen in

       The DisplayHeightMM macro returns the height of the specified screen in

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

       The  DisplayWidthMM  macro returns the width of the specified screen in

       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;

       AllPlanes(3X11),	     BlackPixelOfScreen(3X11),	    IsCursorKey(3X11),

       Xlib -- C Language X Interface
