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

SYNTAX
     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.

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

     The DisplayWidthMM macro returns the width of the specified screen in
     millimeters.
