ImageByteOrder(3X11)
X11R6
NAME
  ImageByteOrder, BitmapBitOrder, BitmapPad, BitmapUnit, DisplayHeight,
  DisplayHeightMM, DisplayWidth, DisplayWidthMM, XListPixmapFormats,
  XPixmapFormatValues - image format functions and macros

SYNOPSIS
  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 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 specified 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;
