  9.      _l_i_b_i_m_p provides a C Language application programming interface (API) for
  10.      reading and writing Silicon Graphics Image Format files and for
  11.      performing a number of format independent image processing operations.
  12.      These format independent operations include color space conversion and
  13.      filtered image zooming.
  14.  
  15.      _l_i_b_i_m_p provides all functionality of the _l_i_b_i_m_a_g_e library. In addition,
  16.      _l_i_b_i_m_p provides function prototypes, a documented interface, reliable
  17.      error reporting and a number of other enhancements.

  20.      A program that calls _l_i_b_i_m_p functions must include the _i_m_p._h header file
  21.      located in the ////uuuussssrrrr////iiiinnnncccclllluuuuddddeeee directory. In addition, the program must link
  22.      with the _l_i_b_i_m_p._a library located in ////uuuussssrrrr////lllliiiibbbb. The link line would look
  23.      like:

  28.      The _l_i_b_i_m_p library consists of two main sets of functions. The first set
  29.      of functions performs operations on SGI Image Format files. The second
  30.      set of functions performs operations on image data in a format
  31.      independent manner.

  107.      The _l_i_b_i_m_p library is based heavily on the _l_i_b_i_m_a_g_e and _l_i_b_g_u_t_i_l
  108.      libraries. These libraries have been available as gifts for a number of
  109.      years on SGI workstations. The principal author of these libraries is
  110.      Paul Haeberli. The zooming code is adapted from the _l_i_b_g_u_t_i_l izoom code
  111.      written by Paul Haeberli and Paul Heckbert.
