NAME
     ImageByteOrder, BitmapBitOrder, BitmapPad, BitmapUnit,
     DisplayHeight, DisplayHeightMM, DisplayWidth, DisplayWidthMM
     - image format macros

SYNOPSIS
     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.

     screen_number
               Specifies the appropriate screen number on the
               host server.

DESCRIPTION
     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.
